Technical Field
[0003] The disclosed embodiments generally relate to non-classical (eg, quantum) computing systems and methods that utilize dopant molecules contained in a host material as qubits. Background Art
[0004] Non-classical computers (e.g., quantum computers) typically use quantum mechanical phenomena, such as superposition, entanglement, and interference, to perform computational operations on data. Compared to classical computers that use binary digits (bits) that always have a defined state (0 or 1), non-classical computers use quantum bits (qubits for short) that can exist in a superposition of basic states (i.e., a certain linear combination of the basic state |0> and the basic state |1>, where the basic states |0> and |1> are orthogonal). Individual qubits of non-classical computers can be entangled with other qubits (i.e., the quantum states of two or more qubits can be correlated so that operations on one qubit affect the state of the entangled qubit). Quantum operations can be performed to guide the state of the qubit to converge probabilistically to a specific final state, which represents a solution to a problem. For certain classes of problems, non-classical computers can converge to the solution faster than any known algorithm can achieve on a classical computer. In some cases, this "quantum advantage" can allow non-classical computers to solve problems that would be intractable using any known classical computer. These problems range from factoring large relatively prime numbers (used, for example, to crack modern cryptographic hash functions), searching for specific items in large amounts of data, and simulating the chemical behavior of drugs, materials, or other molecules.

[0025] Reference will now be made in detail to the exemplary embodiments discussed with respect to the accompanying drawings. Unless otherwise defined, technical and / or scientific terms have the meanings commonly understood by those of ordinary skill in the art. The disclosed embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosed embodiments. It should be understood that other embodiments may be utilized and may be changed without departing from the scope of the disclosed embodiments. Therefore, materials, methods, and examples are merely illustrative and are not intended to necessarily limit.
[0026] As used herein, the term "or" shall convey both a disjunctive and a conjunctive meaning, as long as such meaning is possible. For example, the phrase "A or B" shall be interpreted as including element A alone, element B alone, and a combination of elements A and B, as long as such meaning is possible. As another example, the phrase "A, B, or C" shall be interpreted as including element A alone, element B alone, element C alone, a combination of elements A and B but not element C, a combination of elements A and C but not element B, a combination of elements B and C but not element A, and a combination of elements A, B, and C, as long as such meaning is possible.
[0027] In the drawings (ie, "FIGs." or "Figs."), like numbers refer to like elements.
[0028] Non-classical computers (e.g., quantum computers) typically use quantum mechanical phenomena, such as superposition, entanglement, and interference, to perform computational operations on data. Compared to classical computers that use binary digits (bits) that always have a defined state (0 or 1), non-classical computers use quantum bits (abbreviated as qubits) that can exist in a superposition of basic states (i.e., a certain linear combination of the basic state |0> and the basic state |1>). Individual qubits of non-classical computers can be entangled with other qubits (i.e., the quantum states of two or more qubits can be correlated so that operations on one qubit affect the state of the entangled qubit). Quantum operations can be performed to guide the state of the qubits to converge probabilistically to a solution to a problem. For certain classes of problems, non-classical computers can converge to the solution faster than any known algorithm can achieve on a classical computer. In some cases, this "quantum advantage" can allow non-classical computers to solve problems that would be intractable using any known classical computer. These problems include factoring large relatively prime numbers (e.g., for cracking modern cryptographic hash functions), searching for specific items in large amounts of data, and simulating the chemical behavior of drugs, materials, or other molecules.
[0029] Many chemical and physical systems have been proposed for use as qubits in non-classical computers. For example, a large number of resources have been directed to superconducting qubits that utilize Josephson junctions (i.e., superconductor-insulator-superconductor transitions). Such superconducting qubits use different quantum tunneling modes through the Josephson junction as basic states. These superconducting qubits can be manufactured using well-known semiconductor manufacturing techniques, allowing relatively simple circuit designs. However, superconducting qubits have many disadvantages. For example, superconducting qubits typically must be cooled to a few tenths of a degree above absolute zero, thus requiring a complex cryogenic system. The use of such complex low temperatures also makes it difficult to entangle more than a few qubits, and limits the ultimate computing power of non-classical computers based on superconducting qubits.
[0030] Many other systems have been used as qubits, including arrays of trapped ions, arrays of trapped neutral atoms, and chemical defects in solid-state lattices. One system proposed for quantum computing is the so-called nitrogen-vacancy (NV) center in diamond. The electron spin associated with the NV center can be optically initialized, and its spin state can be read out by fluorescence detection. In addition, the electron spin can be manipulated by microwave (MW) or radio frequency (RF) irradiation, and can exhibit relatively long relaxation and coherence times. However, existing NV quantum computers can only support a limited number of qubits before deleterious effects associated with increasing the number of qubits cause relaxation and coherence times to decrease, thereby negating the very properties that make NV quantum computers attractive in the first place. This is due to the high density of carbon-13 ( 13 C) The natural abundance of spin is 1.1%. 13 The number of C spins increases, increasing the 13 The isotopic concentration of C spins leads to the deterioration of NV center properties. In addition, 13 The random distribution of C spins will lead to couplings on a very wide range of scales, some of which 13 The C spin is very strongly coupled to the NV center (e.g., for adjacent 13 C spin case). This can make NV centers difficult to manipulate and control. In addition, since each NV center 13 The random distribution of C spins has different correlations 13 C spin bath, therefore, NV qubits work almost exclusively with a single NV spin, resulting in a low signal-to-noise ratio (SNR) and the need to perform nonclassical computations multiple times to achieve a measurable signal. In addition, it can be difficult to prepare diamond that can be controllably doped with NV centers, as it can be difficult to prepare highly crystalline diamond with controlled NV doping rates.
[0031] Therefore, there is a need for qubits based on chemical or physical systems that avoid the problems associated with known qubits. Ideally, such chemical or physical systems should be relatively simple to manufacture, support hundreds or thousands of qubits on a single device, allow each qubit to be manipulated independently of every other qubit, and have a coherent lifetime that is much longer than the time required to perform a quantum operation on each qubit. Systems consistent with the disclosed embodiments may meet some or all of these criteria and, therefore, provide technical improvements in performing nonclassical computing.
[0032] As used herein, the terms "non-classical computing," "non-classical programs," "non-classical operations," and "non-classical computers" generally refer to any system or method for performing computational procedures outside the classical computing paradigm. Non-classical computing, non-classical programs, non-classical operations, or non-classical computers may include quantum computing, quantum programs, quantum operations, or quantum computers.
[0033] As used herein, the terms "quantum computing," "quantum program," "quantum operation," and "quantum computer" generally refer to any method or system for performing computations on a Hilbert space represented by a quantum device using quantum mechanical operations (e.g., unitary transformations or completely positive definite trace preserving (CPTP) mappings on a quantum channel). Thus, quantum and classical (or digital) computing can be similar in that both computations can include a sequence of instructions that are performed on input information and then provide an output. Various paradigms of quantum computing can decompose quantum operations into sequences of elementary quantum operations that simultaneously affect subsets of qubits of a quantum device. Quantum operations can be selected based on, for example, their location or the ease of their physical implementation. A quantum program or computation can then consist of a sequence of such instructions that, in various applications, can represent different quantum evolutions on a quantum device. For example, programs that compute or simulate quantum chemistry can represent quantum states and annihilation and creation operators of electron spin orbits by using qubits (e.g., two-level quantum systems) and a universal set of quantum gates (e.g., Hadamard, controlled non-(CNOT), and π / 8 rotation) through the so-called Jordan-Wigner transformation or Bravyi-Kitaev transformation.
[0034] Additional examples of quantum programs or computations may include programs for optimization, such as quantum approximate optimization algorithms (QAOA) or quantum minimum discovery. QAOA may include gates that perform rotations of a single qubit and entangle multiple qubits. In quantum adiabatic computing, instructions may carry a random or non-random path for the evolution of an initial quantum system to a final quantum system. Quantum derivative programs may include simulated annealing, parallel tempering, master equation solvers, Monte Carlo programs, quantum algorithms for approximating maximum independent sets, and the like. Quantum classical or hybrid algorithms or programs may include programs such as variational quantum eigensolvers (VQE) and variational and adiabatic navigation quantum eigensolvers (VanQver).
[0035] In general, examples of quantum programs or computations can include any program or computation described in “Quantum Computation and Quantum Information” by MA Nielsen and IL Chuang, Cambridge University Press (2013), which is incorporated herein by reference in its entirety for all purposes.
[0036] A quantum computer may include one or more adiabatic quantum computers, quantum gate arrays, one-way quantum computers, topological quantum computers, quantum Turing machines, quantum annealers, Ising solvers, or gate models of quantum computing.
[0037] Doped host materials as qubits for performing nonclassical computations
[0038] Provided herein are systems and methods for performing non-classical computing. The systems and methods generally utilize dopant molecules contained in organic host materials. Dopant molecules generally act as qubits and are associated with an electronic energy level structure comprising a triple electron manifold. The triple electron manifold may include a ground state triple (GST) electron manifold. The triple electron manifold generally includes three triplets, which can be linearly combined to form a qubit basic state (e.g., with respect to a laboratory reference system, a rotating reference system, or another suitable time-independent or time-dependent reference system). The basic state generally has a long life at a temperature obtainable using a cryogenic system based on liquid helium. Dopant molecules can be arranged in the host material to allow a relatively strong coupling between the nearest neighboring dopant molecules, thereby allowing information to surge on the qubit network through entanglement. The quantum states of various dopant molecules can be manipulated individually using optical, MW, or RF techniques, thereby allowing each qubit to be individually controlled to perform non-classical computing.

In some embodiments, the precursor is completely deuterated. That is, in some embodiments, the precursor originally contains deuterium atoms at each site of the expected hydrogen atom. In some embodiments, the precursor is at least partially labeled with carbon-13. That is, in some embodiments, the precursor originally contains one or more carbon-13 atoms at the expected carbon-13 atom.

[0063] Thus, in some embodiments, the system 100 includes at least one cutting molecule 150. In the example shown, the system 100 includes a plurality of cutting molecules 150.

In some embodiments, the at least one cutting molecule 150 is used to increase the stability of the at least one dopant molecule 120. For example, in some embodiments, the at least one cutting molecule 150 increases the stability of the at least one dopant molecule 120 by kinetically trapping the at least one dopant molecule 120 near the originally reactive dopant molecule 120. In some embodiments, the at least one cutting molecule 150 increases the stability of the at least one dopant molecule 120 by reducing the chemical interaction between the at least one dopant molecule 120 and the host material 110.
[0064] Figure 1B A side view of a system 100 is shown according to various embodiments. In the example shown, the system 100 includes at least one host material 110 and a plurality of dopant molecules 120.
[0065] In the example shown, the body material 110 includes a thickness 160. In some embodiments, the body material 110 includes a thin film. That is, in some embodiments, the thickness 160 is at least about 0.3 nm, 0.4 nm, 0.5 nm, 0.6 nm, 0.7 nm, 0.8 nm, 0.9 nm, 1 nm, 2 nm, 3 nm, 4 nm, 5 nm, 6 nm, 7 nm, 8 nm, 9 nm, 10 nm, 20 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, 200 nm, 300 nm, 400 nm, 500 nm, 600 nm, 700 nm, 800 nm, 900 nm, 1,000 nm, or more, At most about 1,000nm, 900nm, 800nm, 700nm, 600nm, 500nm, 400nm, 300nm, 200nm, 100nm, 90nm, 80nm, 70nm, 60nm, 50nm, 40nm, 30nm, 20nm, 10nm, 9nm, 8nm, 7nm, 6nm, 5nm, 4nm, 3nm, 2nm, 1nm, 0.9nm, 0.8nm, 0.7nm, 0.6nm, 0.5nm, 0.4nm, 0.3nm or less, or in a range defined by any two of the foregoing values. For example, in some embodiments, thickness 160 is between about 0.3 nm and about 1 nm, about 0.3 nm and about 10 nm, about 0.3 nm and about 100 nm, about 0.3 nm and about 1,000 nm, about 1 nm and about 10 nm, about 1 nm and about 10 nm, about 1 nm and about 100 nm, about 1 nm and about 1,000 nm, about 10 nm and about 100 nm, about 10 nm and about 1,000 nm, or about 100 nm and about 1,000 nm. In some embodiments, using a thin film host material 110 allows for the formation of a pseudo-two-dimensional (pseudo-2D) layer of dopant molecules 120, as described herein.
[0066] In some embodiments, the thin film is formed on a substrate ( Figure 1B) on top of the substrate. In some embodiments, the substrate includes a main material 110. In some embodiments, the substrate includes a micro-machining process material, such as silicon, glass, or sapphire. In some embodiments, the thin film is formed using one or more micro-machining techniques, such as wet cleaning, Piranha cleaning, RCA cleaning, surface passivation, spin coating, dip coating, chemical vapor deposition (CVD), atmospheric pressure CVD, low pressure CVD, ultra-high vacuum CVD, aerosol-assisted CVD, direct liquid jet CVD, hot wall CVD, cold wall CVD, microwave plasma-assisted CVD, plasma enhanced CVD (PECVD), remote PECVD, low energy PECVD, atomic layer CVD, combustion CVD, rapid thermal CVD, photoinduced CVD, laser CVD, vapor phase epitaxy, physical vapor deposition, sputtering deposition, evaporative deposition, pulsed laser deposition, pulsed electron deposition, atomic layer deposition, molecular beam epitaxy, etching, wet etching, dry etching, reactive ion etching (RIE), deep RIE, atomic layer etching, or self-assembly (to form a self-assembled monolayer).
[0067] In some embodiments, the thickness 160 of the body material 110 is at least about 1 nm, 2 nm, 3 nm, 4 nm, 5 nm, 6 nm, 7 nm, 8 nm, 9 nm, 10 nm, 20 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, 200 nm, 300 nm, 400 nm, 500 nm, 600 nm, 700 nm, 800 nm, 900 nm, 100 nm, 200 nm, 300 nm, 400 nm, 500 nm, 600 nm, 700 nm, 800 nm, 900 nm, 1 micrometer (μm), 2 μm, or more. m, 3μm, 4μm, 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 20μm, 30μm, 40μm, 50μm, 60μm, 70μm, 80μm, 90μm, 100μm, 200μm m, 300μm, 400μm, 500μm, 600μm, 700μm, 800μm, 900μm, 1 millimeter (mm), 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10 mm or larger, up to about 10mm, 9mm, 8mm, 7mm, 6mm, 5mm, 4mm, 3mm, 2mm, 1mm, 900μm, 800μm, 700μm, 600μm, 500μm, 400μm , 300μm, 200μm, 100μm, 90μm, 80μm, 70μm, 60μm, 50μm, 40μm, 30μm, 20μm, 10μm, 9μm, 8μm, 7μm, 6μm, 5μm, 4μ In some embodiments, the body material 110 is not formed on the substrate.
[0068] In the example shown, a plurality of dopant molecules 120 are arranged in a pseudo-2D layer. In some embodiments, the pseudo-2D layer includes a sheet of space to which the plurality of dopant molecules 120 are confined. In some embodiments, a carrier may be drawn between each pair of dopant molecules 120 in the pseudo-2D layer. In some embodiments, the carrier is angled with respect to a plane defined by the host material 110. In some embodiments, the angle is at least about 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, or 90 degrees, at most about 90, 85, 80, 75, 70, 65, 60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, or 0 degrees, or within a range defined by any two of the foregoing values. In some embodiments, the pseudo-2D layer comprises a self-assembled monolayer (SAM). In some embodiments, arranging the plurality of dopant molecules 120 in a pseudo-2D layer reduces the extent to which each of the plurality of dopant molecules 120 must interact with its nearest neighbors located substantially above or below it, thereby simplifying the quantum dynamics of the plurality of dopant molecules 120 .
[0069] Although Figure 1B A pseudo-2D layer of a thin sheet of space to which the various dopant molecules 120 are confined is depicted, but the disclosed embodiments are not limited thereto. In some embodiments, the various dopant molecules 120 may be disposed within a thicker layer. In such a thicker layer, each of the various dopant molecules 120 may interact with a nearest neighbor located substantially above or below it.
[0070] Electron triplet states used as fundamental states of qubits
[0071] Figure 2 An example of an electronic energy level diagram 200 of a GST molecule is shown. In some embodiments, a GST molecule is used as a qubit (e.g., as described herein with respect to Figure 1A and 1B qubits described). In the example shown, the GST molecule is associated with a GST electron manifold 210, a first singlet electronic state 220, a second singlet electronic state 230, and an excited state triplet (EST) electron manifold 240. In some embodiments, the GST electron manifold 210 includes a first triplet state 211, a second triplet state 212, and a third triplet state 213. In some embodiments, the first triplet state 211, the second triplet state 212, and the third triplet state 213 represent the lowest energy electronic states of the GST molecule. In some embodiments, the first triplet state 211 is represented by |T 1> indicates that the second triplet state 212 is represented by |T 2 >, and the third triplet state 213 is represented by |T 3 > represents. In some embodiments, the EST electron manifold 240 includes a first triplet state 241, a second triplet state 242, and a third triplet state 243. In some embodiments, the first singlet electronic state 220, the second singlet electronic state 230, and the EST electron manifold 240 each represent a higher energy electronic state than the GST molecule. Figure 2 As depicted in , in some embodiments, the energy of the second singlet electronic state 230 is lower than the EST electron manifold 240. However, in other embodiments, the energy of the second singlet electronic state 230 is higher than the EST electron manifold 240.
[0072] In some embodiments, under thermal equilibrium, the GST electronic state 210 is highly populated (i.e., the electronic wave function of the GST molecule is heavily biased to the GST electronic state 210, with relatively equal contributions to the first triplet state 211, the second triplet state 212, and the third triplet state 213), while the first singlet electronic state 220, the second singlet electronic state 230, the first triplet state 241, the second triplet state 242, and the third triplet state 243 are not highly populated.
[0073] In some embodiments, the GST molecules are configured to absorb electromagnetic energy to drive the population from the first triplet state 211, the second triplet state 212, or the third triplet state 213 to the first singlet state 220, the second singlet state 230, the first triplet state 241, the second triplet state 242, or the third triplet state 243. In some embodiments, the GST molecules are configured to relax back to the first triplet state 211, the second triplet state 212, or the third triplet state 213 via radiative decay; or relax back to the first singlet state 220 or the second singlet state 230 via intersystem crossing (ISC). In some embodiments, continuous absorption of electromagnetic energy selectively drives the population into any combination of the first triplet state 211, the second triplet state 212, and the third triplet state 213, thereby generating a non-equilibrium electronic state distribution. In this way, any combination of the first triplet state 211, the second triplet state 212, and the third triplet state 213 can be "hyperpolarized" as described herein.
[0074] In some embodiments, the first triplet state |T 1 >, the second triplet state |T 2 > and the third triplet state |T 3 > can be used as a qubit basis state for non-classical computing. Thus, a qubit may include: a first qubit basis state, wherein the first qubit basis state is a first triplet state |T 1 >, the second triplet state |T 2 > and the third triplet state |T 3> (e.g., with respect to a laboratory reference frame, a rotating reference frame, or another suitable time-independent or time-dependent reference frame) (e.g., a first qubit basis state |0>=α 1 |T 1 >+α 2 |T 2 >+α 3 |T 3 >); and a second qubit base state, wherein the second qubit base state is the first triplet state |T 1 >, the second triplet state |T 2 > and the third triplet state |T 3 > (e.g., the second qubit basis state |1>=β 1 |T 1 >+β 2 |T 2 >+β 3 |T 3 >). Usually, α 1 , α 2 , α 3 , β 1 , β 2 and β 3 They can each satisfy the normalization condition |α 1 | 2 +|α 2 | 2 +|α 3 | 2 =1 and |β 1 | 2 +|β 2 | 2 +|β 3 | 2 = 1. In addition, α should usually be chosen 1 , α 2 , α 3 , β 1 , β 2 and β 3 Such that the first qubit basis state and the second qubit basis state are different from each other (eg, orthogonal).

[0076] In some embodiments, the lifetime is defined as the half-life of the electronic state of the qubit returning from a hyperpolarized electronic state distribution to a thermal equilibrium electronic state distribution. In some embodiments, the lifetime is measured at the intended operating temperature of the qubit, e.g., at least about 1 K, 2 K, 3 K, 4 K, 5 K, 6 K, 7 K, 8 K, 9 K, 10 K, 15 K, 20 K, 25 K, 30 K, 35 K, 40 K, 45 K, 50 K or more, at most about 50 K, 45 K, 40 K, 35 K, 30 K, 25 K, 20 K, 15 K, 10 K, 9 K, 8 K, 7 K, 6 K, 5 K, 4 K, 3 K, 2 K, 1 K or less, or at a temperature between any two of the foregoing values (e.g., between about 4 K and about 20 K). In some embodiments, lifetime is measured at a temperature of at least about 1 K, 2 K, 3 K, 4 K, 5 K, 6 K, 7 K, 8 K, 9 K, 10 K, 15 K, 20 K, 25 K, 30 K, 35 K, 40 K, 45 K, 50 K or more, at most about 50 K, 45 K, 40 K, 35 K, 30 K, 25 K, 20 K, 15 K, 10 K, 9 K, 8 K, 7 K, 6 K, 5 K, 4 K, 3 K, 2 K, 1 K or less.

[0077] Optical hyperpolarization and initialization of qubit states
[0078] In some embodiments, hyperpolarization allows non-classical computations to be performed with high signal-to-noise ratios (SNRs). In some embodiments, hyperpolarization allows qubits to be initialized in a first qubit basis state or a second qubit basis state (or any linear combination thereof), thereby initializing non-classical computations. In some embodiments, hyperpolarization allows coherent manipulation of the quantum states of qubits to perform non-classical computations.
[0079] In some embodiments, hyperpolarization allows one or more qubits to be placed in a particular quantum state (e.g., a first qubit basis state, a second qubit basis state, or any linear combination thereof). In some embodiments, the qubits are initialized after such hyperpolarization.
[0080] In the case of a GST molecule, in some embodiments, hyperpolarization describes a condition where the electronic state population in one state (e.g., the first singlet electronic state of the GST molecule) is relatively close to that in another state (e.g., the first triplet electronic state of the GST molecule). 1 >, the second triplet state |T 2 > and the third triplet state |T 3 >any combination) exceeds the absolute value of the corresponding differences in thermal equilibrium.
[0081] In some embodiments, the population difference between two electronic states is the difference between the populations of the two electronic states divided by the total population of the two electronic states. The population difference can be expressed as a fractional population difference or a percentage population difference. In some embodiments, the population difference (expressed as a percentage) is at least about 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or more, at most about 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1% or less, or within a range defined by any two of the foregoing values.
[0082] As described herein, in some embodiments, the qubit is configured to absorb electromagnetic energy to drive the population into a first triplet state |T 1 >, the second triplet state |T 2 > and the third triplet state |T 3 >, thereby generating hyperpolarization. In some embodiments, the electromagnetic energy has a central wavelength selected to drive the population to the first triplet state |T 1 >, the second triplet state |T 2 > and the third triplet state |T 3> any combination of. In some embodiments, the central wavelength is within the infrared (IR), visible, or ultraviolet (UV) portion of the electromagnetic spectrum. In some embodiments, the central wavelength is at least about 200 nm, 210 nm, 220 nm, 230 nm, 240 nm, 250 nm, 260 nm, 270 nm, 280 nm, 290 nm, 300 nm, 310 nm, 320 nm, 330 nm, 340 nm, 350 nm, 360 nm, 370 nm, 380 nm, 390 nm, 400 nm, 410 nm, 420 nm, 430 nm, 440 nm, 450 nm, 460 nm, 470 nm, 480 nm, 490 nm, 500 nm, 510 nm, 520 nm, 530 nm, 540 nm, 550 nm, 560 nm, 570 nm, 580 nm, 590 nm, 600 nm, 610 nm, 620 nm, 630 nm, 640 nm, 650 nm, 660 nm, 670 nm, 680 nm, 690 nm, 700 nm, 710 nm, 720 nm, 730 nm, 740 nm, 750 nm, 760 nm, 770 nm, 780 nm, 790 nm, 800 nm, 1000 nm, 1010 nm, 1020 nm, 1030 nm, 1040 nm, 1050 nm, 1060 nm, 1070 nm, 1080 nm, 1090 nm, 1100 nm, 1110 nm, 1120 nm, 1130 nm, 1140 nm, 1150 nm, 1160 nm, 1170 nm, 1180 nm, 1190 nm, 2000 nm, 2010 nm, 2020 nm, 2030 nm, 2040 nm, 2050 nm, 2060 nm, 2070 nm, 2080 nm, 2090 nm, 2100 nm, 2110 nm, 2120 nm, 2130 nm, 2140 nm, 2150 nm, 2160 nm, 2170 nm, 2180 nm,000nm, 990nm, 980nm, 970nm, 960nm, 950nm, 940nm, 930nm, 920nm, 910nm, 900 nm, 890nm, 880nm, 870nm, 860nm, 850nm, 840nm, 830nm, 820nm, 810nm, 800nm, 7 90nm, 780nm, 770nm, 760nm, 750nm, 740nm, 730nm, 720nm, 710nm, 700nm, 690n m, 680nm, 670nm, 660nm, 650nm, 640nm, 630nm, 620nm, 610nm, 600nm, 590nm, 58 0nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm, 100nm,
[0083] Optical initialization of individual qubits
[0084] return Figure 1A and 1B In some embodiments, different dopant molecules 120 experience different physicochemical environments due to their different positions or orientations in the host material 110. In some embodiments, different physicochemical environments cause different dopant molecules 120 to have slightly different electronic energy level structures. For example, Figure 2 As discussed in the foregoing, the energy difference between any two of the first triplet state 211, the second triplet state 212, the third triplet state 213, the first singlet electronic state 220, the second singlet state 230, the first triplet state 241, the second triplet state 242 and the third triplet state 243 can depend on the physicochemical environment of the associated dopant molecules, thereby changing the wavelength or frequency of the electromagnetic energy required to drive the transition between the two states.
[0085] return Figure 1A and 1BAs discussed above, in some embodiments, the different electronic energy level structures of the dopant molecules 120 may allow for individual addressing of each dopant molecule 120. For example, if the bandwidth of the optical energy used to initialize each dopant molecule is sufficiently narrow (e.g., the bandwidth is small compared to the difference between the wavelength required to initialize a given dopant molecule 120 and the wavelength required to initialize other dopant molecules 120), each dopant molecule 120 may be individually optically addressed.
[0086] For example, the first dopant molecule 120 and the second dopant molecule 120 may have different electronic energy level structures. Therefore, in some embodiments, the first dopant molecule 120 may be configured to absorb a first electromagnetic energy having a first central wavelength, and the second dopant molecule 120 may be configured to absorb a second electromagnetic energy having a second central wavelength. In some embodiments, the first central wavelength or the second central wavelength includes any central wavelength described herein. In some embodiments, the first central wavelength and the second central wavelength are different from each other.
[0087] In some embodiments, the first center wavelength is associated with a first wavelength range having a first bandwidth. In some embodiments, the first bandwidth is measured as a first full width at half maximum (FWHM). In some embodiments, the second center wavelength is associated with a second wavelength range having a second bandwidth. In some embodiments, the second bandwidth is measured as a second FWHM bandwidth. In some embodiments, the first bandwidth or the second bandwidth is at least about 1 MHz, 2 MHz, 3 MHz, 4 MHz, 5 MHz, 6 MHz, 7 MHz, 8 MHz, 9 MHz, 10 MHz, 15 MHz, 20 MHz, 25 MHz, 30 MHz, 35 MHz, 40 MHz, 45 MHz, 50 MHz, 55 MHz, 60 MHz, 65 MHz, 70 MHz, 75 MHz, 80 MHz, 85 MHz, 90 MHz, 95 MHz, 100 MHz or more and at most about 100 MHz, 95 MHz, 90 MHz, 85 MHz, 80 MHz, 75 MHz, 70 MHz, 65 MHz, 60 MHz, 55 MHz, 50 MHz, 45 MHz, 40 MHz, 35 MHz, 30 MHz, 25 MHz, 20 MHz, 15 MHz, 10 MHz, 9 MHz, 8 MHz, 7 MHz, 6 MHz, 5 MHz, 4 MHz, 3 MHz, 2 MHz, 1 MHz or less, or within a range defined by any two of the foregoing values.
[0088] In some embodiments, the first wavelength range and the second wavelength range are different. In some embodiments, the first wavelength range and the second wavelength range (e.g., within the first FWHM and the second FWHM) do not overlap. In some embodiments, the first FWHM and the second FWHM are similar to or wider than the bandwidth of the light source directed to the first dopant molecule 120 and the second dopant molecule 120. In some embodiments, the non-overlapping nature of the first wavelength range and the second wavelength range allows the first dopant molecule 120 to absorb light energy while the second dopant molecule 120 does not absorb light energy. In some embodiments, the non-overlapping nature of the first wavelength range and the second wavelength range allows the second dopant molecule 120 to absorb light energy while the first dopant molecule 120 does not absorb light energy. This procedure may be referred to as "separate optical initialization" of the first dopant molecule and the second dopant molecule 120. In some embodiments, the separate optical initialization of the first dopant molecule and the second dopant molecule 120 causes the first dopant molecule and the second dopant molecule 120 to emit different amounts of light energy. In some embodiments, measuring the light energy collapses the quantum state of at least one dopant molecule into an electronic energy eigenstate of at least one dopant molecule, thereby initializing the dopant molecule to a desired initial quantum state.
[0089] Although discussed from the perspective of two dopant molecules 120, the principles of separate optical initialization described herein can be extended to any number of dopant molecules 120. For example, separate optical initialization can be applied to at least about 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000, or more dopant molecules 120, Up to about 10,000, 9,000, 6,000, 5,000, 4,000, 3,000, 2,000, 1,000, 900, 800, 700, 600, 500, 400, 300, 200, 100, 90, 80, 70, 60, 50, 40, 30, 20, 10, 9, 8, 7, 6, 5, 4, 3 or 2 dopant molecules 120, or a number of dopant molecules 120 within a range defined by any two of the foregoing values.
[0090] Such individual optical initialization may be particularly useful for qubits based on dopant molecules 120. As described herein, such dopant molecules 120 may be separated from each other by a relatively small distance compared to a typical beam waist. For example, in some embodiments, the dopant molecules 120 are separated from each other by a distance of less than 10 nm (or any other separation distance described herein) in order to ensure proper coupling between nearest neighboring dopant molecules 120. In some embodiments, a typical beam waist may be approximately 500 nm, such that the optical energy will hit approximately 5,000 qubits. Thus, even when the optical energy is directed to hundreds or thousands of qubits, individual optical initialization may allow manipulation of individual qubits.
[0091] In some embodiments, individual optical initialization of qubits may allow for individual initialization of qubits in a first qubit basis state or a second qubit basis state (or any linear combination thereof), thereby initializing non-classical computation.
[0092] RF or MW manipulation of individual qubits
[0093] In some embodiments, the first qubit state and the second qubit state described herein are separated by an energy difference in the RF or MW portion of the electromagnetic spectrum. Thus, in some embodiments, manipulation of the quantum state of each qubit can be performed using RF or MW energy. Furthermore, in some embodiments, the different physicochemical environments of the different dopant molecules 120 produce a wavelength or frequency shift that is insufficient to allow optical initialization of each qubit individually. In such embodiments, multiple qubits can first be optically initialized simultaneously using, for example, a broadband light source, as described herein. In some embodiments, the quantum state of each qubit is then manipulated individually using RF or MW energy.
[0094] In some embodiments, the first dopant molecule 120 can be configured to absorb first electromagnetic energy having a first center frequency, and the second dopant molecule 120 can be configured to absorb second electromagnetic energy having a second center frequency. In some embodiments, the first center frequency or the second center frequency is at least about 1 MHz, 2 MHz, 3 MHz, 4 MHz, 5 MHz, 6 MHz, 7 MHz, 8 MHz, 9 MHz, 10 MHz, 20 MHz, 30 MHz, 40 MHz, 50 MHz, 60 MHz, 70 MHz, 80 MHz, 90 MHz, 100 MHz, 200 MHz, 300 MHz, 400 MHz, 500 MHz, 600 MHz, 700 MHz, 800 MHz, 900 MHz, 1 gigahertz (GHz), 2 GHz, 3 GHz, 4 GHz, 5 GHz, 6 GHz, 7 GHz, 8 GHz, 9 GHz, 10 GHz, 20 GHz, 30 GHz, 40 GHz, 50 GHz, 60 GHz, 70 GHz, 80 GHz, 90 GHz, 100 GHz In some embodiments, the first center frequency or the second center frequency is in the RF or MW portion of the electromagnetic spectrum.
[0095] In some embodiments, the first center frequency and the second center frequency are different from each other. In some embodiments, the first center frequency is associated with a first frequency range having a first bandwidth. In some embodiments, the first bandwidth is measured as a first FWHM bandwidth. In some embodiments, the second center frequency is associated with a second frequency range having a second bandwidth. In some embodiments, the second bandwidth is measured as a second FWHM bandwidth. In some embodiments, the first bandwidth or the second bandwidth depends on the power of the RF or MW energy supplied to the first dopant molecule or the second dopant molecule 120. In some embodiments, the first bandwidth or the second bandwidth includes a natural bandwidth of the first dopant molecule or the second dopant molecule 120. For example, in some embodiments, the first bandwidth or the second bandwidth is at least about 100 Hz, 200 Hz, 300 Hz, 400 Hz, 500 Hz, 600 Hz, 700 Hz, 800 Hz, 900 Hz, 1 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, 6 kHz, 7 kHz, 8 kHz, 9 kHz, 10 kHz, 20 kHz, 30 kHz, 40 kHz, 50 kHz, 60 kHz, 70 kHz, 80 kHz, 90 kHz, 100 kHz, 200 kHz, 300 kHz, 400 kHz, 500 kHz, 600 kHz, 700 kHz, 800 kHz, 900 kHz, 1 MHz, 2 MHz, 3 MHz, 4 MHz, 5 MHz, 6 MHz, 7 MHz, 8 MHz, 9 MHz, 10 MHz, 20 MHz, 30 MHz, 40 MHz, 50 MHz, 60 MHz, 70 MHz, 80 MHz, 90 MHz, 100 MHz, or more. , up to about 100 MHz, 90 MHz, 80 MHz, 70 MHz, 60 MHz, 50 MHz, 40 MHz, 30 MHz, 20 MHz, 10 MHz, 9 MHz, 8 MHz, 7 MHz, 6 MHz, 5 MHz, 4 MHz, 3 MHz, 2 MHz, 1 MHz, 900 kHz, 800 kHz, 700 kHz, 600 kHz, 500 kHz, 400 kHz, 300 kHz, 200 kHz, 100 kHz, 90 kHz, 80 kHz, 70 kHz, 60 kHz, 50 kHz, 40 kHz, 30 kHz, 20 kHz, 10 kHz, 9 kHz, 8 kHz, 7 kHz, 6 kHz, 5 kHz, 4 kHz, 3 kHz, 2 kHz, 1 kHz, 900 Hz, 800 Hz, 700 Hz, 600 Hz, 500 Hz, 400 Hz, 300 Hz, 200 Hz, 100 Hz or less, or in a range defined by any two of the foregoing values.
[0096] In some embodiments, the first frequency range and the second frequency range are different. In some embodiments, the first frequency range and the second frequency range (e.g., within the first FWHM and the second FWHM) do not overlap. In some embodiments, the first FWHM and the second FWHM are similar to or narrower than the bandwidth of the RF or MW energy directed to the first dopant molecule 120 and the second dopant molecule 120. In some embodiments, the non-overlapping nature of the first frequency range and the second frequency range allows the first dopant molecule 120 to absorb RF or MW energy while the second dopant molecule 120 does not absorb RF or MW energy. In some embodiments, the non-overlapping nature of the first frequency range and the second frequency range allows the second dopant molecule 120 to absorb RF or MW energy while the first dopant molecule 120 does not absorb RF or MW energy. This procedure can be referred to as "separate RF or MW manipulation" of the first dopant molecule and the second dopant molecule 120.
[0097] Although discussed from the perspective of two dopant molecules 120, the principles of separate RF or MW manipulation described herein can be extended to any number of dopant molecules 120. For example, separate RF or MW manipulation can be applied to at least about 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000, or more dopant molecules 120, up to about 10 ,000, 9,000, 8,000, 7,000, 6,000, 5,000, 4,000, 3,000, 2,000, 1,000, 900, 800, 700, 600, 500, 400, 300, 200, 100, 90, 80, 70, 60, 50, 40, 30, 20, 10, 9, 8, 7, 6, 5, 4, 3 or 2 dopant molecules 120, or a number of dopant molecules 120 within a range defined by any two of the foregoing values.
[0098] Such separate RF or MW manipulation may be particularly useful for qubits based on dopant molecules 120. As described herein, such dopant molecules 120 may be separated from each other by a relatively small distance compared to a typical beam waist. For example, in some embodiments, the dopant molecules 120 are separated from each other by a distance less than 10 nm (or any other separation distance described herein) in order to ensure proper coupling between nearest neighboring dopant molecules 120. In some embodiments, a typical beam waist may hit hundreds or thousands of qubits, as described herein.
[0099] Thus, following optical initialization of the qubits (either individually or simultaneously), individual RF or MW manipulations can allow individual coherent manipulation of the quantum state of each qubit. In some embodiments, the coherent manipulations include the implementation of at least one non-classical operation. In some embodiments, the non-classical operations include any of the non-classical operations described herein.
[0100] Storing nonclassical information in nuclear spin degrees of freedom
[0101] In some embodiments, nonclassical information (e.g., information obtained during or after implementation of any nonclassical operation described herein) can be transferred from the electronic state of at least one dopant molecule 120 to the nuclear spin state of at least one dopant molecule 120 or at least one nearby molecule (referred to as a "nearby host molecule") contained within the host material 110. In some embodiments, the information can be transferred by implementing an exchange gate between the electronic state and the nuclear spin state of at least one dopant molecule 120. In some embodiments, the exchange gate can be implemented by applying RF or MW energy to the at least one dopant molecule 120 and the nuclear spin state, as described herein.
[0102] In some embodiments, transferring nonclassical information to nuclear spin states provides an increase in readout fidelity, initialization fidelity, or lifetime, thereby improving the overall fidelity of nonclassical computing.
[0103] Optical readout of individual qubits
[0104] In some embodiments, the different electronic energy level structures of the dopant molecules 120 can allow for the individual optical readout of the quantum state of each dopant molecule 120 after non-classical operations. For example, the quantum state of each dopant molecule 120 can be individually optically readout based on the wavelength of light emitted by the dopant molecule 120, which can vary based on the physicochemical environment of each dopant molecule 120.
[0105] In some embodiments, each dopant molecule 120 is configured to absorb light and emit light. In some embodiments, the optical properties of the light emitted by each dopant molecule 120 are related to the quantum state of the associated dopant molecule 120. For example, in some embodiments, the dopant molecule 120 in the first qubit state absorbs and emits light having a first property, while the dopant molecule 120 in the second qubit state absorbs and emits light having a second property. In some embodiments, the dopant molecule in a linear superposition between the first qubit state and the second qubit state absorbs and emits light having a linear superposition of the first property and the second property. In some embodiments, the first property is different from the second property. Therefore, in some embodiments, measuring the light emitted by the dopant molecule 120 allows the quantum state of the dopant molecule 120 to be determined at the time of measurement. In some embodiments, the first property or the second property includes the intensity of the light emitted by the dopant molecule 120. In some embodiments, the first property or the second property includes the polarization state of the light emitted by the dopant molecule 120. In some embodiments, the first property or the second property includes the wavelength of the light emitted by the dopant molecule 120. In some embodiments, the first property or the second property includes the frequency of the light emitted by the dopant molecule 120.

[0231] Examples
[0232] Example 1: General synthesis and characterization procedures
[0233] Commercially available materials were used without purification unless otherwise noted. Moisture and oxygen sensitive reactions were performed using syringe / septum techniques in flame-dried glassware and under an inert atmosphere of purified argon. 254 Thin layer chromatography (TLC) was performed on aluminum plates. The plates were visualized using ultraviolet (UV) light at wavelengths of 254 nm and 365 nm. 1 H at 400.13MHz and for 13 C at 100.61MHz or for 1 H at 600.15MHz and for 13 C NMR spectra were recorded on a Bruker Avance Neo 400 MHz or Bruker Avance Neo 600 MHz spectrometer operating at 150.94 MHz. NMR chemical shifts (δ) are reported in parts per million (ppm). 1 H and 13 C spectra, the solvent signal was used for internal calibration ( 1 H NMR: δ(CHCl 3 )=7.26; 13 C NMR: δ(CDCl 3 )=77.16). Recorded in proton decoupling mode 13 C NMR spectra. Coupling constants (J) are given in Hz and apparent resonance multiplicities are reported as s (singlet), d (doublet), t (triplet), q (quartet), quint (quintet), or m (multiplet). HC Duo column was used as solid phase. The Selekt rapid purification system was used for rapid chromatography. Electron paramagnetic resonance (EPR) spectra were recorded on an X-band EPR spectrometer (Bruker ELEXSYSE580), with software xEPR used for data acquisition. Measurements were made using a dielectric ring resonance (Bruker model 4118X-MD5, typical microwave frequency of about 9.7 GHz), which was installed in a helium flow cryostat (Oxford CF935) with an optical access. When operated in continuous wave (cw) mode, a typical quality factor of about 10,000 was achieved, and the typical modulation amplitude and frequency were 1 Gauss (G) and 100 kHz, respectively. In the pulsed model, a Bruker SpinJet arbitrary waveform generator (Applied Systems Engineering Model 117) with a 1 kW traveling wave tube (TWT) amplifier was used. Prior to measurement, the sample was inserted into an EPR tube (Wilmade Quartz CFQ) with an outer diameter (OD) of 4 millimeters (mm) and aligned on a homemade Teflon sample stage. The sample can be rotated using a single-axis goniometer stage (Bruker E218G1).
[0234] Example 2: General synthetic route for forming carbene dopant molecules
[0235] The general synthetic route for forming carbene dopant molecules in organic host materials is shown below.
[0236]
[0237] Carbenes are designed to have a triplet ground state in which two unpaired electrons are confined to nearby molecular orbitals. As a result, electronic coupling is maximized and the zero-field partitioning parameters D and E of the electron spins are large. In addition, the spin-lattice relaxation times benefit from the weak spin-orbit coupling that is typically present in pure organic materials. Carbenes can be contained in a cyclic structure (1) and include two (2) or one (3) aryl or heteroaryl π 1-3 , which may be substituted with one or more nitrile, carbonyl, carboxylic acid, ester, alkyl, aryl, heteroaryl, amine, nitro, phosphine, alcohol, ether, thioether, or halogen groups. Such groups may be selected (e.g., using computational molecular modeling, high throughput synthesis and screening, etc.) to fine tune electronic properties, such as ZFS, zero phonon lines, spectral stability, and / or thermodynamic / kinetic stability.
[0238] Since carbenes are generally not stable enough to prepare dilute molecular crystals directly, a stable carbenes precursor is instead embedded in a molecular matrix (compounds 4-6) and then activated (i.e., converted from the carbenes precursor form to the activated carbenes form). The carbenes precursor generally includes a diaryldiazo group (R 2 C=N- - =N), which can be photoactivated with light (λ = 200 to 500 nm) to generate dinitrogen N 2 An example of such activation is shown below.
[0239]
[0240] The host materials (compounds 6-9) in which carbenes are embedded are generally designed so that they are structurally similar to carbenes precursors 1-3, respectively, and can form rare molecule crystals by replacing the host material (i.e., matrix) molecules by the carbenes precursors. This isostructural relationship allows the preparation of high-quality rare molecule crystals by reducing the amount of strain imparted by the dopant molecules (i.e., carbenes). Both carbenes and host materials can be partially or completely deuterated to reduce magnetic noise in rare molecule crystals, and thus enhance the spin-spin coherence time T 2 Using bottom-up synthetic chemistry, molecules can also be selectively 13 C (e.g., at the carbene carbon) labeling, adding a nuclear spin manifold that can be used for quantum state preparation. The close packing of molecules in the supramolecular arrangement helps by placing the inert N2 Molecular trapping in close proximity to the reactive carbene center stabilizes the carbene and thereby isolates it from any nearby reaction partners.
[0241] Example 3: Synthesis of compounds required for inserting di(naphthalene-2-yl)carbene into di(naphthalene-2-yl)methanone
[0242] The synthetic route for forming the di(naphthalene-2-yl)carbene dopant molecule in the di(naphthalene-2-yl)methanone host material is shown below.

[0326] g) Formation of di(naphthalene-2-yl)methanone- 13 Cd 14 (diazomethylene) dinaphthalene - 13 Cd 14 Diluted molecular crystals
[0327] Di(naphthyl)methanone- 13 Cd14 (0.80 g) was dissolved in hot ethyl acetate (HPLC grade, 90 mL, 0.030 M) and the solution was allowed to cool to room temperature. To this solution was added 2,2'-(diazomethylene) dinaphthyl- 13 Cd 14 (4.5 mg, 5400 ppm). An aliquot (5 milliliters, mL) of the resulting parent solution was added to a 10 mL vial using a syringe equipped with a 0.45 μm pore size syringe filter, and the vial was placed in a screw-top jar filled with ethanol (HPLC grade). Storage in the dark for 7 days at room temperature formed rare molecular crystals (parallelepiped, approximately 3×3×4 mm). The crystals were separated in the dark, washed with ethanol (HPLC grade) and dried in a vacuum. The rare molecular crystals can be stored in a freezer (T=-22° C.) in the dark for several months without detectable degradation.
[0328] In order to di(naphthalene-2-yl)methanone- 13 Cd 14 Di(naphthalene-2-yl)carbene- 13 Cd 14 Dopant molecules, only need to di (naphthalene-2-yl) ketone- 13 Cd 14 (diazomethylene) dinaphthalene 13 Cd 14 The dilute molecular crystals are exposed to light of the correct wavelength, as described herein.
[0329] Example 8: X-ray crystal structure of (diazomethylene) dinaphthalene embedded in di(naphthalene-2-yl)methanone
[0330] Diluted single crystals of 2,2'-(diazomethylene)binaphthalene embedded in di(naphthalene-2-yl)methanone were grown by slow vapor diffusion of ethanol into a solution of 2,2'-(diazomethylene)binaphthalene (340 ppm) and dilute solutions of ethyl acetate of di(naphthalene-2-yl)methanone (0.035 M) at room temperature over seven days in the dark. Appropriate crystals were selected and the Cu-K α radiation The Atlas diffractometer was mounted on a SuperNova, Dual, Cu. During data collection, the crystal was kept at 150.00 (14) Kelvin. The structure was solved using Olex2, the XT structure solver using the intrinsic phase method, and refined using the XL refinement package using the least squares method. All non-H atoms were refined with anisotropic thermal parameters. The H atoms in all structures were refined in the rigid group model at calculated positions. Table 1 shows the resulting crystal data. Due to the nature of the diffraction measurements, only periodically assembled molecules (i.e., the bulk material) appear in the crystal structure, and no carbene precursors are observed.

[0335] Example 9: General synthetic route for forming nitrene dopant molecules
[0336] The general synthetic route for forming nitrene dopant molecules in organic host materials is shown below.
[0337]
[0338] Nitren materials are prepared following principles similar to those outlined above for the preparation of carbenes. That is, a photoactive nitrene precursor is embedded in an inert matrix (i.e., a host material) by substitutional doping, and after photolysis using an appropriate light source, the activated nitrene 10 is obtained. Nitenes can be attached directly to aryl groups or via sulfonyl (SO 2 -) linker connection. Substituents at the nitrene aryl unit can be used to fine-tune thermodynamic / kinetic stability and electronic properties. Here, again, one or more substituents R can be attached, such as one or more nitrile, carbonyl, carboxylic acid, ester, alkyl, aryl, heteroaryl, imine, amine, nitro, phosphine, alcohol, ether, thiol, thioether, or halogen groups. As in the case of carbenes, such groups can be selected (e.g., using computational molecular modeling, high-throughput synthesis and screening, etc.) to fine-tune electronic properties, such as ZFS, zero phonon lines, spectral stability, and / or thermodynamic / kinetic stability.
[0339] The precursors of nitrene (10) are aryl azides (–N 3 , 11), aryl isocyanate (-NCO, 12), or iminoiodoalkane (13). Each of these groups can be photolyzed with UV / visible light (λ = 200 to 500 nm) to afford nitrene and dinitrogen, respectively. 2 , carbon monoxide CO or an aryl iodide molecule.
[0340]
[0341] An exemplary approach for embedding an aryl azide precursor (15) into a structurally related matrix (16) is shown below.
[0342]
[0343] Example 10: Formation of rare molecular crystals of 4-azidobenzoic acid in 4-iodobenzoic acid
[0344] 4-Iodobenzoic acid (1.00 g) was dissolved in methanol (HPLC grade, 50 mL, 0.080 M) and the solution was cooled to room temperature. In the dark, 4-azidobenzoic acid (0.2 M in tert-butyl methyl ether, ≥95.0%, 130 μL, 6600 ppm) was added to this solution. An aliquot (8 milliliters, mL) of the resulting parent solution was added to a 10 mL vial using a syringe equipped with a 0.20 μm pore size syringe filter and the vial was stored in the dark for 4 days at room temperature. Dilute molecular crystals (thin rectangular plates, about 5×10×0.01 mm) were isolated in the dark, washed with a small amount of cold methanol (HPLC grade) and dried in a vacuum.
[0345] To generate 4-azidobenzoic acid dopant molecules in a 4-iodobenzoic acid host material, it is only necessary to expose a crystal of a dilute 4-azidobenzoic acid molecule in 4-iodobenzoic acid to light of the correct wavelength, as described herein.
[0346] Example 11: Optical crystal alignment for characterizing dopant molecules in host materials
[0347] The chemical system formed by embedding dopant molecules (or their precursors) into a host material may also be referred to herein as a "rare molecule crystal". Rare molecule crystals exhibit intrinsic birefringence, i.e., optical anisotropy. This property can be used to identify a set of axes of the material (i.e., an orthogonal axis system of optical refractive index ellipse axes n1, n2, and n3) for later comparison in an experimental setup. A microscope in transmission mode with two crossed linear polarizers (denoted as polarizer and analyzer) can be used to identify such axes.
[0348] Here, examples are given of typical configurations when the crystal is rotated in the field of view. Whenever the crossed polarizer axes are parallel to the vectors n1 and n2 (or more generally, to their projections in a plane perpendicular to the viewing direction), the crystal appears dark, whereas in the case of the crystal positioned in all other orientations, some light will pass through the analyzer and the crystal displays varying degrees of visible brightness. The maximum brightness of the birefringent material is observed when the polarizer and analyzer axes are at an angle of 45° relative to n1 and n2. This method can also be used to inspect the crystal for the presence of microscopic defects, such as strain-induced elongation effects (e.g., edge or screw dislocations).
[0349] Example 12: Preparation, photoactivation and annealing of carbene in host materials
[0350] After the crystal index ellipsoid has been macroscopically determined by the above-mentioned optical alignment method, a crystal of appropriate size is prepared from the original crystal by micromechanical methods (e.g., blade cutting, diamond wire saw, etc.), and if necessary, the surface is cut or polished with a suitable organic solvent (e.g., hexane, pentane, ethanol, methanol). The prepared crystal is transferred to a suitable sample holder (e.g., electron paramagnetic resonance (EPR) tube, glass sample holder, etc.) and placed in an apparatus of interest (e.g., EPR, optical instrument) together with an integrated cryostat. The sample is cooled to a temperature at which the generated carbene or nitrene is stable (depending on the carbene or nitrene itself and the matrix). Using an integrated optical access such as an optical fiber or window, the sample is irradiated with light (e.g., UV LED with a wavelength range between 300 and 400nm) in a macroscopic manner for a certain amount of time (depending on the light source output power, from a few seconds to a few hours) to activate the entire sample. This process involves converting the carbene or nitrene precursor molecule embedded in a suitable matrix into its corresponding carbene and a dinitrogen molecule (for nitrene, carbon monoxide and aryl iodide are also possible). Alternatively, a focused laser beam that can be adjusted in the lateral dimensions (x and y axis) can be used to activate regions of carbene or nitrene with a size > 200 nm.
[0351] Fig. 6A Shown is an exemplary continuous wave (cw) EPR signal associated with the stepwise photoactivation of di(naphth-2-yl)carbene (500 ppm) in di(naphth-2-yl)methanone using a green laser (λ=532 nm) at a temperature of 25 K. The appearance of the ground state triplet carbene can be seen. Figure 6B shows the change of applied light energy Fig. 6AThe double integral of the cw EPR signal of , and depicts the activation process for obtaining activated carbenes in dilute molecular crystals. Such a graph can be used as a calibration curve for activating dopant molecules (e.g., carbenes dopant molecules) in dilute molecular crystals. By using such a calibration curve (i.e., the amount of carbenes activated per irradiation), a well-defined carbenes density can be generated within the doped molecular crystal. The qubit pattern can be written into the sample (e.g., gradients, connecting regions, lattices) using photolithographic methods.
[0352] For very low temperatures (<140K in some cases, below 260K for other samples), carbene and dinitrogen molecules are dynamically trapped within the matrix, preventing them from adopting the molecular geometry typical of carbene. An annealing procedure involves controllably raising the temperature of the sample to a sample-dependent temperature (here 140K, for other samples >50K) for a sufficient amount of time (several minutes to several hours), which triggers a reorientation of the activated carbene and its immediate molecular environment within the dilute molecular crystal. The process can be monitored by cw EPR.
[0353] Fig. 7A Shown is an exemplary cw EPR signal associated with the conversion of di(naphthalen-2-yl)carbene (340 ppm) in freshly photoactivated di(naphthalen-2-yl)methanone to the annealed form at a temperature of 140 K. The annealing process is observed as the disappearance of the cw EPR signal at 6925 G and the appearance of a new signal at 7065 G. Figure 7B The annealing time is shown Fig. 7A The double integration of the cw EPR signal is usually accompanied by line sharpening and can therefore be used to further control the inhomogeneous broadening within the sample, which is required for efficient single-molecule manipulation by optical control. Figure 7B The appearance and disappearance of the annealing signal and the non-annealing signal at a specific time are shown, respectively.

[0355] The sample di(naphthalene-2-yl)methanone-d was measured at 466.6 mT. 14 Di(naphth-2-yl)carbene-d 14 (5400ppm) spin-lattice (T 1 ) relaxation time, where the magnetic field is roughly parallel to the zero-field splitting tensor B 0 ||D X A principal axis. 1The measurements were made using an inversion recovery sequence with Hahn echo based detection (π-T-π / 2-τ-π-τ-echo). The measurements were made using rectangular 10 ns π / 2 pulses and 20 ns π pulses with 16-step phase cycling. The data were fitted using a stretched exponential function to extract T 1 The average and maximum values of T 1 Deviations from the monoexponential behavior of the curve can be associated with inhomogeneities in the microscopic spin environment in the sample, for example, through an inhomogeneous distribution of carbene spins. It can be rewritten as a continuous distribution of a single exponential function, where the distribution can be expressed according to T 1,char and exponent β to evaluate its mean value (T 1,av ) and the most likely value (T 1,max ). Fig. 8A An exemplary decay curve is shown as well as a temperature for extracting T at 3.5 K. 1 Stretched exponential fit curves of the time average and maximum values. Figure 8B Shown in the temperature range of 3.5K to 25K T 1 Exemplary graphs of the temperature dependence of the time average and most probable values.
[0356] The spin-spin (T) was measured using a Hahn-echo pulse sequence (π / 2-τ-π-τ-echo). 2 ) relaxation times and fitted to a stretched exponential decay similar to the procedure described above. The measurements used rectangular 10 nsπ / 2 pulses and 20 nsπ pulses with four-step phase cycling. Fig. 9 The decay curves of protonated and deuterated dilute molecular crystals are shown, and the T of the dilute molecular crystal after full deuteration is highlighted. 2 For example, for the protonated sample (di(naphthalene-2-yl)carbene in di(naphthalene-2-yl)methanone (5400 ppm)), a most likely value T of 4.78 μs was observed. 2,max and an average T of 2.67μs 2,av , while the fully deuterated sample di(naphthalene-2-yl)methanone-d 14 Di(naphth-2-yl)carbene-d 14 (5400ppm) gives the most likely value T of 53.6μs 2,max and an average value T of 16.0μs 2,av We note that the line shapes of these spectra may be distorted due to inhomogeneous broadening and electron spin echo envelope modulation (ESEEM) effects caused by the coupling of electron spins to nearby hydrogen and deuterium nuclei, respectively.
[0357] Example 14: Di(naphthalene-2-yl)methanone-d 14 Di(naphth-2-yl)carbene-d 14 The intermolecular coupling strength
[0358] Double electron-electron resonance (DEER) experiments were performed to probe the intermolecular coupling between randomly distributed carbenes in dilute molecular crystals. While sweeping the magnetic field, echo-detected field sweep spectra were collected using a Hahn-echo pulse sequence with a fixed τ value. In the DEER experiment, due to the 13 Ultrafine coupling (HFC) of C carbenes, using a crystal orientation B 0 ||D Y A large coupling of 214.6 MHz is observed to selectively address the probe and pump pulses. The π-pump pulse optimized by adiabatic inversion chirped pulses flips the coupled complexes and thus the probe spins experience additional decoherence due to static 2-pole coupling with the pump spins during the entire evolution time of the sequence. For example, Fig.10 The curve decays for the experiment with the pump pulse turned off and on are shown, along with the time elapsed for each decay that the initial signal has fallen to 1 / e. The two groups refer to different photoactivation steps (partial activation and full activation), which further highlights the tunability of the intermolecular coupling.

The appearance of the ground state triazine can be seen. Fig. 11B The activation time is shown Fig.11A The double integral of the cw EPR signal of , and depicts the activation process for obtaining activated nitrenes in dilute molecular crystals. Such a graph can be used as a calibration curve for activating dopant molecules (e.g., nitrene dopant molecules) in dilute molecular crystals. By using such a calibration curve (i.e., the amount of nitrenes activated per irradiation), a well-defined nitrene density can be generated within a doped molecular crystal. The qubit pattern can be written into the sample (e.g., gradient, connecting region, lattice) using photolithographic methods.
