[0037] Although various embodiments of the present invention have been shown and described herein, it will be apparent to those skilled in the art that these embodiments are provided as examples only. Various modifications, variations and substitutions may be envisioned by those skilled in the art without departing from the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be adopted.

[0038] Unless otherwise defined, all technical terms used herein have the same meaning as those commonly understood by those of ordinary skill in the art to which the present invention belongs. As used in this specification and the appended claims, the singular forms "a", "an", and "the" include plural forms unless the context clearly dictates otherwise. Any reference to "or" herein is intended to encompass "and / or" unless otherwise indicated.

[0039] When the term "at least", "greater than", or "greater than or equal to" precedes the first value in a series of two or more values, the term "at least", "greater than", or "greater than or equal to" applies to each value in the series. For example, greater than or equal to 1, 2, or 3 is equivalent to greater than or equal to 1, greater than or equal to 2, or greater than or equal to 3.

For example, less than or equal to 3, 2, or 1 is equivalent to less than or equal to 3, less than or equal to 2, or less than or equal to 1.

[0041] When values ​​are described as ranges, it should be understood that such disclosure includes disclosure of all possible sub-ranges within such ranges as well as specific values ​​falling within such ranges, whether or not a specific value or a specific sub-range is expressly stated.

[0042] As used herein, like characters refer to like elements.

[0043] As used herein, the terms "artificial intelligence," "artificial intelligence process," "artificial intelligence operation," and "artificial intelligence algorithm" generally refer to any system or computing process that takes one or more actions to enhance or maximize the chances of successfully achieving a goal. The term "artificial intelligence" may include "generative modeling," "machine learning" (ML), and / or "reinforcement learning" (RL).

[0044] As used herein, the terms "machine learning," "machine learning process," "machine learning operation," and "machine learning algorithm" generally refer to any system or analytical and / or statistical process performed by a computer that gradually improves a task. Machine learning may include a machine learning algorithm. A machine learning algorithm may be a trained algorithm. Machine learning (ML) may include one or more supervised, semi-supervised, or unsupervised machine learning techniques. For example, an ML algorithm may be a trained algorithm trained by supervised learning (e.g., various parameters are determined as weights or scaling factors). ML may include one or more of regression analysis, regularization, classification, dimensionality reduction, ensemble learning, meta-learning, association rule learning, cluster analysis, anomaly detection, deep learning, or ultra-deep learning. ML can include, but is not limited to: k-means, k-means clustering, k-nearest neighbors, learning vector quantization, linear regression, nonlinear regression, least squares regression, partial least squares regression, logistic regression, stepwise regression, multivariate adaptive regression splines, ridge regression, principal component regression, least absolute shrinkage and selection operations, least angle regression, canonical correlation analysis, factor analysis, independent component analysis, linear discriminant analysis, multidimensional scaling, non-negative matrix factorization, principal component analysis, principal coordinate analysis, projection pursuit, Sammon mapping, t-distributed random neighbor embedding, adaptive boosting (AdaBoosting), boosting, ladder boosting, guided aggregation, ensemble averaging, decision tree, conditional decision tree, boosted decision tree, gradient boosted decision tree, random forest, stacked generalization, Bayesian network, Bayesian belief network, Naive Bayes, Gaussian Naive Bayes, Multinomial Naive Bayes, Hidden Markov Model, Hierarchical Hidden Markov Model, Support Vector Machine, Encoder, Decoder, Autoencoder, Stacked Autoencoder, Perceptron, Multilayer Perceptron, Artificial Neural Network, Feedforward Neural Network, Convolutional Neural Network, Recurrent Neural Network, Long Short-Term Memory, Deep Belief Network, Deep Boltzmann Machine, Deep Convolutional Neural Network, Deep Recurrent Neural Network, or Generative Adversarial Network.

[0045] As used herein, the terms "reinforcement learning," "reinforcement learning process," "reinforcement learning operation," and "reinforcement learning algorithm" are intended to refer to any system or computational process that takes one or more actions to enhance or maximize some notion of the cumulative reward of its interaction with an environment. An agent performing a reinforcement learning (RL) process may receive positive or negative reinforcement, called "immediate rewards," from taking one or more actions in an environment and thereby placing itself and the environment in various new states.

[0046] The goal of the agent may be to enhance or maximize some concept of cumulative reward. For example, the goal of the agent may be to enhance or maximize a "discounted reward function" or an "average reward function". A "Q function" can represent the maximum cumulative reward that can be obtained from a state and the actions taken in that state. "Value functions" and "generalized advantage estimators" can represent the maximum cumulative reward that can be obtained from a state given an optimal or best action selection. RL can utilize any one or more of these cumulative reward concepts. As used herein, any such function can be referred to as a "cumulative reward function". Therefore, calculating the best or optimal cumulative reward function can be equivalent to finding the best or optimal policy for the agent.

[0047] The agent and its interaction with the environment can be formulated as one or more Markov decision processes (MDPs). The RL process may not assume knowledge of the exact mathematical model of the MDP. The MDP may be completely unknown, partially known, or completely known to the agent. With respect to prior knowledge of the MDP, the RL process may be in the range between the two degrees of "model-based" or "model-free". Thus, the RL process may be targeted at large MDPs, where exact methods may not be feasible or available due to the unknown or stochastic nature of the MDP.

[0048] The RL process can be implemented using one or more computer processors described herein. A digital processing unit can train, store, and then deploy a "strategy" using an agent to enhance or maximize a cumulative reward. A strategy can be sought (e.g., searched) over as long a period of time as possible or desired. Such optimization problems can be solved by storing an approximation of the optimal strategy, by storing an approximation of the cumulative reward function, or by both. In some cases, the RL process can store one or more tables of approximated values ​​for such functions. In other cases, the RL process can use one or more "function approximators."

[0049] Examples of function approximators may include neural networks (such as deep neural networks) and probabilistic graphical models (e.g., Boltzmann machines, Helmholtz machines, and Hopfield networks). A function approximator may create a parameterization of an approximation of a cumulative reward function. Optimization of a function approximator in terms of its parameterization may include perturbing parameters by perturbing the function approximator to more closely satisfy Bellman's optimality criterion (such as in temporal difference methods) or in a direction that enhances or maximizes the cumulative reward and thereby enhances or optimizes the policy (such as in policy gradient methods).

[0050] During training, the agent can take actions in the environment to gain more information about the environment and about good or optimal strategy choices for survival or better utility. The agent's actions can be randomly generated (e.g., especially in the early stages of training) or can be dictated by another machine learning paradigm (such as supervised learning, imitation learning, or any other machine learning process described herein). The agent's actions can be refined by selecting actions that are closer to the agent's perception of what an enhanced or optimal strategy is. With respect to the choice between exploration and exploitation, various training strategies can range between two degrees of off-policy and on-policy approaches.

[0051] As used herein, the terms "non-classical computing," "non-classical processes," "non-classical operations," and "non-classical computers" generally refer to any method or system for performing a computational process outside the paradigm of classical computing. Non-classical computing, non-classical processes, non-classical operations, or non-classical computers may include quantum computing, quantum processes, quantum operations, or quantum computers.

[0052] As used herein, the terms "quantum computing", "quantum process", "quantum operation" and "quantum computer" generally refer to any method or system for performing calculations using quantum mechanical operations (such as unitary transformations or completely positive trace preservation (CPTP) mappings on quantum channels) on a Hilbert space represented by a quantum device. As such, quantum computing and classical (or digital) computing may be similar in that both computations may include a sequence of instructions executed 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 a subset 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 process or computation can then consist of a series of such instructions that can represent different quantum evolutions on a quantum device in various applications. For example, a process of computing or simulating quantum chemistry can be represented by using qubits (such as two-level quantum systems) and universal quantum gate sets (such as Hadamard, non-controlled (CNOT) and π / 8 rotations) through the so-called Jordan-Wigner transformation or Bravyi-Kitaev transformation to represent the quantum states and annihilation and creation operators of electron spin orbits.

[0053] Other examples of quantum processes or computations may include processes for optimization, such as the quantum approximation optimization algorithm (QAOA) or quantum minimum finding. QAOA may include gates that perform rotations of single qubits and entanglement of multiple qubits. In quantum adiabatic computation, instructions may carry a random or non-random evolution path from an initial quantum system to a final quantum system.

[0054] Quantum inspired processes may include simulated annealing, parallel tempering, master equation solvers, Monte Carlo processes, etc. Quantum classical or hybrid algorithms or processes may include processes such as the variational quantum eigensolver (VQE) and the variational and adiabatic navigated quantum eigensolver (VanQver).

[0055] 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.

[0065] The system 200 may include one or more electromagnetic delivery units 220. The electromagnetic delivery unit may include any electromagnetic delivery unit described herein, such as those described herein with respect to Figure 4 The electromagnetic delivery unit described herein can be configured to apply electromagnetic energy to one or more atoms in the plurality of atoms. Applying electromagnetic energy can induce the atoms to adopt one or more superposition states of a first atomic state and a second atomic state different from the first atomic state.

[0066] The first atomic state may include a first single qubit state. The second atomic state may include a second single qubit state. The first atomic state or the second atomic state may be elevated in energy relative to a base atomic state of the atom. The energy of the first atomic state or the second atomic state may be equal to the base atomic state of the atom.

[0067] The first atomic state may include a first hyperfine electronic state and the second atomic state may include a second hyperfine electronic state different from the first hyperfine electronic state. For example, the first and second atomic states may include first and second hyperfine states on a multistate manifold such as a triplet manifold. The first and second atomic states may include 3 P1 or 3 The first and second hyperfine states on the P2 manifold. The first and second atomic states may include any of the atoms described herein. 3 P1 or 3 The first and second hyperfine states on the P2 manifold, such as strontium-87 3 P1 manifold or Strontium-87 3 P2 manifold.

[0068] Fig. 9 The inclusion of strontium-87 3 Example of a qubit in the P2 state. Fig. 9 The left panel shows the Sr-87 3 The rich energy level structure of the P2 state. Fig. 9 The right panel shows the Sr-87 3 Potential qubit transitions within the P2 state are insensitive (to first order) to changes in the magnetic field around 70 Gauss.

[0069] In some cases, the first and second atomic states are first and second hyperfine states of a first electronic state. Photoexcitation may be applied between the first electronic state and the second electronic state. Photoexcitation may excite the first hyperfine state and / or the second hyperfine state to the second electronic state. The single qubit transition may include a two-photon transition between two hyperfine states within the first electronic state using the second electronic state as an intermediate state. To drive the single qubit transition, a pair of frequencies may be applied to drive the two-photon transition, each frequency being detuned from the single-photon transition to the intermediate state. In some cases, the first and second hyperfine states are hyperfine states of a ground electronic state. The ground electronic state may not decay to a lower electronic state by spontaneous or stimulated emission. Hyperfine states may include nuclear spin states. In some cases, hyperfine states include strontium-87 1 The nuclear spin state of the S0 manifold, and the quantum bit transition will strontium-87 1 One or both of the two nuclear spin states of S0 are driven to 3 P2 or 3 In some cases, single-qubit transitions are made via 3 P2 or 3 P1 manifold or from its detuned state in Sr-87 1Two-photon Raman transitions between nuclear spin states of S0. In some cases, the nuclear spin state can be a Stark-shifted nuclear spin state. The Stark shift can be driven optically. The optical Stark shift can be driven by any, all, or combination of single-qubit transitions, double-qubit transitions, shelving transitions, imaging transitions, and the like.

[0070] The first atomic state may include a first nuclear spin state and the second atomic state may include a second nuclear spin state different from the first nuclear spin state. The first and second atomic states may include the first and second nuclear spin states of a quadrupole nucleus, respectively. The first and second atomic states may include the first and second nuclear spin states of a spin-1, spin-3 / 2, spin-2, spin-5 / 2, spin-3, spin-7 / 2, spin-4, or spin-9 / 2 nucleus, respectively. The first and second atomic states may include the first and second nuclear spin states of any atom described herein, such as the first and second spin states of strontium-87, respectively.

[0071] For first and second nuclear spin states associated with nuclei that include a spin greater than 1 / 2 (such as spin-1, spin-3 / 2, spin-2, spin-5 / 2, spin-3, spin-7 / 2, spin-4, or spin-9 / 2 nuclei), transitions between the first and second nuclear spin states may be accompanied by transitions between other spin states on the nuclear spin manifold. For example, for a spin-9 / 2 nucleus in the presence of a uniform magnetic field, all nuclear spin energy levels may be separated by equal energy. Thus, a transition designed to move an atom from, for example, m N =9 / 2 spin state transferred to m N =7 / 2 spin transitions (such as Raman transitions) can also drive: m N =7 / 2 to m N =5 / 2, m N =5 / 2 to m N =3 / 2, m N =3 / 2 to m N =1 / 2, m N =1 / 2 to m N =-1 / 2, m N =-1 / 2 to m N =-3 / 2, m N =-3 / 2 to m N =-5 / 2, m N =-5 / 2 to m N = -7 / 2, and m N =-7 / 2 to m N = -9 / 2, where m N is the nuclear spin state. Similarly, it is designed to move atoms from, for example, m N =9 / 2 spin state transferred to m N =5 / 2 spin transitions (such as Raman transitions) can also drive: mN =7 / 2 to m N =3 / 2, m N =5 / 2 to m N =1 / 2, m N =3 / 2 to m N =-1 / 2, m N =1 / 2 to m N =-3 / 2, m N =-1 / 2 to m N =-5 / 2, m N =-3 / 2 to m N = -7 / 2, and m N =-5 / 2 to m N = -9 / 2. Therefore, this transition may not selectively induce a transition between specific spin states on the nuclear spin manifold. Alternatively, it may be desirable to achieve a selective transition between specific first and second spin states on the nuclear spin manifold. This can be achieved by providing light from a light source that provides an AC Stark shift and pushes adjacent nuclear spin states away from resonance with the transition between the desired transition between the first and second nuclear spin states. For example, if it is desired to transition from a state having m N = -9 / 2 and m N = -7 / 2, the first and second nuclear spin states transition, then the light can provide m N = -5 / 2 spin state AC Stark shift, thus greatly reducing m N = -7 / 2 and m N = -5 / 2 state. Similarly, if we want to N = -9 / 2 and m N = -5 / 2, the first and second nuclear spin states transition, then the light can provide m N = -1 / 2 spin state AC Stark shift, thus greatly reducing m N = -5 / 2 and m N = -1 / 2 states. This can effectively create a two-level subsystem within the nuclear spin manifold that is decoupled from the rest of the nuclear spin manifold, greatly simplifying the dynamics of the qubit system. It can be advantageous to use nuclear spin states near the edge of the nuclear spin manifold (e.g., for spin -9 / 2 nuclei, m N = -9 / 2 and m N =-7 / 2, m N =7 / 2 and m N =9 / 2, m N = -9 / 2 and m N = -5 / 2, or m N =5 / 2 and m N=9 / 2), so only one AC Stark shift is required. Alternatively, one can use nuclear spin states that are farther from the edge of the nuclear spin manifold (e.g., m N = -5 / 2 and m N =-3 / 2 or m N = -5 / 2 and m N = -1 / 2) and two AC Stark shifts can be achieved (e.g., at m N = -7 / 2 and m N = -1 / 2 or m N = -9 / 2 and m N =3 / 2).

[0072] Stark shifting of the nuclear spin manifold can deviate adjacent nuclear spin states from resonance with the desired transition between the first and second nuclear spin states and the second electronic state or a state detuned therefrom. Stark shifting can reduce leakage from the first and second nuclear spin states to other states in the nuclear spin manifold. For beam powers less than 10 mW, Stark shifting can reach 100 kHz. Higher state frequency selectivity can reduce scattering caused by imperfect polarization control. 3 The separation of different angular momentum states in the P1 manifold can be many gigahertz different from the single-qubit and two-qubit gate light. Additional states leaking into the nuclear spin manifold can cause decoherence. The Rabi frequency of a two-qubit transition (e.g., how fast a transition can be driven) can be faster than the decoherence rate. Scattering from intermediate states in a two-qubit transition can be a source of decoherence. Detuning from intermediate states can improve the fidelity of two-qubit transitions.

[0073] Qubits based on nuclear spin states in the electronic ground state can allow the use of long-lived metastable excited electronic states (such as those in strontium-87) 3 The P0 state) is used for qubit storage. Atoms can be selectively transferred to this state to reduce crosstalk or improve gate or detection fidelity. Using the SLM or AOD described herein, such storage or shelving processes can be atom selective. Shelving transitions can include 1 S0 state to Sr-87 3 P0 or 3 Transitions between P2 states.

[0074] Clock transitions (also referred to herein as "shelving transitions" or "storage transitions") can be qubit state selective. The higher state of the clock transition can have a very long natural lifetime, for example greater than 1 second. The linewidth of the clock transition can be much narrower than the qubit energy spacing. This can allow direct spectral resolution. The population can be transferred from one of the qubit states to the clock state. This can allow individual single qubit states to be read out - first transferring the population from one qubit state to the clock state, imaging the qubit, and then transferring the population from the clock state back to the ground state and imaging again. In some cases, a magic wavelength transition is used to drive the clock transition.

[0075] The clock light used for shelving can be atom-selective or non-atom-selective. In some cases, the clock transition is globally applied (e.g., not atom-selective). A globally applied clock transition can include guiding light without passing through a microscope objective or structuring the light. In some cases, the clock transition is atom-selective. Atom-selective clock transitions may allow us to improve gate fidelity by minimizing crosstalk. For example, in order to reduce crosstalk in atoms, atoms can be shelved in clock states where they are not affected by light. This can reduce crosstalk between adjacent qubits undergoing transitions. In order to achieve atom-selective clock transitions, light can pass through one or more microscope objectives and / or can be structured on one or more of a spatial light modulator, a digital micromirror device, a cross-acoustic-optic deflector, and the like.

The objective lens may have a NA within the range defined by any two of the above values.

[0077] One or more readout optical units 230 can perform measurements, such as projection measurements, by applying light that resonates with the imaging transition. The imaging transition may cause fluorescence. The imaging transition may include the 1 S0 state to Sr-87 1 The induction between P1 states. 1 The P1 state may fluoresce. The lower states of the qubit transition may include 1 Two nuclear spin states in the S0 manifold. One or more of the states may be in resonance with the imaging transition. The measurement may include two excitations. In the first excitation, one of the two lower states may be excited to a resting state (e.g., 3 P0 state). In the second excitation, the imaging transition can be excited. The first transition can reduce crosstalk between neighboring atoms during calculations. The fluorescence generated from the imaging transition can be collected on one or more readout optical units 230.

[0085] The system 200 may include one or more entanglement units 280. The entanglement unit may be configured to quantum mechanically entangle at least a first atom of the plurality of atoms with at least a second atom of the plurality of atoms. The first or second atom may be in a superposition state at the moment of quantum mechanical entanglement. Alternatively or in combination, the first or second atom may not be in a superposition state at the moment of quantum mechanical entanglement.

The Rydberg excitation unit may be configured to allow the Rydberg atom or modified Rydberg atom to relax to a lower energy atomic state, thereby forming one or more dual qubit units. The Rydberg excitation unit may be configured to induce the Rydberg atom or modified Rydberg atom to relax to a lower energy atomic state.

The Rydberg excitation cell can be configured to induce any number of quantum mechanical entanglements between any number of atoms in the plurality of atoms.

[0087] The Rydberg excitation unit may include one or more light sources (such as any light source described herein) configured to emit light having one or more ultraviolet (UV) wavelengths. The UV wavelength may be selected to correspond to the wavelength at which the Rydberg atoms or modified Rydberg atoms are formed.

The light may include one or more wavelengths of at most about 400nm, 390nm, 380nm, 370nm, 360nm, 350nm, 340nm, 330nm, 320nm, 310nm, 300nm, 290nm, 280nm, 270nm, 260nm, 250nm, 240nm, 230nm, 220nm, 210nm, 200 nanometers or less. The light may include one or more wavelengths within a range defined by any two of the aforementioned values. For example, the light may include one or more wavelengths within a range from 300nm to 400nm.

[0088] The Rydberg excitation unit may be configured to induce a two-photon transition to generate entanglement. The Rydberg excitation unit may be configured to induce a two-photon transition to generate entanglement between two atoms. The Rydberg excitation unit may be configured to selectively induce a two-photon transition to selectively generate entanglement between two atoms. For example, the Rydberg excitation unit may be configured to guide electromagnetic energy (such as light energy) to a specific optical trapping site to selectively induce a two-photon transition to selectively generate entanglement between two atoms. The two atoms may be trapped in nearby optical trapping sites. For example, two atoms may be trapped in adjacent optical trapping sites. The two-photon transition may be induced using first and second lights from first and second light sources, respectively. The first and second light sources may each include any light source described herein (such as any laser described herein). The first light source may be the same or similar to the light source used to perform the single qubit operation described herein. Alternatively, different light sources may be used to perform single qubit operations and induce two-photon transitions to generate entanglement. The first light source may emit light of one or more wavelengths included in the visible region of the spectrum (e.g., in the range from 400 nm to 800 nm or from 650 nm to 700 nm). The second light source may emit light of one or more wavelengths included in the ultraviolet region of the spectrum (e.g., in the range from 200 nm to 400 nm or from 300 nm to 350 nm). The first and second light sources may emit light having substantially equal and opposite spatially correlated frequency shifts.

[0089] Rydberg atoms or modified Rydberg atoms may include Rydberg states, which may have sufficiently strong interatomic interactions with nearby atoms (such as nearby atoms captured in nearby optical trapping sites) to enable dual qubit operations. Rydberg states may include principal quantum numbers of at least about 50, 60, 70, 80, 90, 100 or more. Rydberg states may include principal quantum numbers of at most about 100, 90, 80, 70, 60, 50 or less. Rydberg states may include principal quantum numbers within a range defined by any two of the aforementioned values. Rydberg states may interact with nearby atoms through van der Waals interactions. Van der Waals interactions may shift the atomic energy levels of atoms.

[0090] Selectively exciting atoms to Rydberg levels can enable two-qubit operations. Two-photon transitions can be used to transfer atoms from a ground state such as 1 S0 ground state) to a Rydberg state (such as n 3 S1 state, where n is the principal quantum number described in this article). State selectivity can be achieved by a combination of laser polarization and spectral selectivity. As described in this article, a two-photon transition can be achieved using a first and a second laser source. The first laser source can emit pi-polarized light, which does not change the projection of the atomic angular momentum along the magnetic field. The second laser can emit circularly polarized light, which can change the projection of the atomic angular momentum along the magnetic field by one unit. Using this polarization, the first and second qubit energy levels can be excited to Rydberg levels. However, the Rydberg levels can be more sensitive to magnetic fields than the ground state, so large splittings can be easily obtained (for example, on the order of 100 MHz). This spectral selectivity can allow state-selective excitation to Rydberg levels.

[0091] Due to the van der Waals interactions described herein, two-qubit operations can rely on energetic shifts in energy levels. Such shifts may prevent the excitation of one atom from being conditional on the state of the other atom, or change the coherent dynamics of the excitations of the two-atom system to perform two-qubit operations. In some cases, "modified states" can be generated under continuous actuation to perform two-qubit operations without fully exciting to Rydberg levels (e.g., as described in https: / / arxiv.org / abs / 1605.05207, which is incorporated herein by reference in its entirety for all purposes).

The optical trapping site may include one or more optical lattice sites in one or more optical lattices. The optical trapping site may include one or more optical lattice sites in one or more one-dimensional (1D) optical lattices, two-dimensional (2D) optical lattices, or three-dimensional (3D) optical lattices.

[0100] An optical lattice can be generated by interfering counter-propagating light (such as counter-propagating lasers) to generate a periodic continuous standing wave pattern with intensity minima and maxima along a specific direction. A one-dimensional optical lattice can be generated by interfering a pair of counter-propagating light beams. A two-dimensional optical lattice can be generated by interfering two pairs of counter-propagating light beams. A 3D optical lattice can be generated by interfering three pairs of counter-propagating light beams. The light beams can be generated by different light sources or by the same light source. Thus, the optical lattice can be generated by at least about 1, 2, 3, 4, 5, 6 or more light sources or at most about 6, 5, 4, 3, 2 or 1 light source.

The laser may emit light having a bandwidth within the range defined by any two of the aforementioned values.

[0112] The light source can be configured to emit light tuned to one or more magic wavelengths corresponding to a plurality of atoms. The magic wavelengths corresponding to the atoms can include light of any wavelength that causes equal or nearly equal polarization rates of the first and second atomic states. The magic wavelength for the transition between the first and second atomic states can be determined by calculating the wavelength-dependent polarization rates of the first and second atomic states and finding the crossover point. Regardless of the intensity of the light emitted by the light source, light tuned to such a magic wavelength can cause equal or nearly equal differential optical shifts in the first and second atomic states. This can effectively decouple the first and second atomic states from the motion of the atoms. The magic wavelength can utilize one or more scalar or tensor optical shifts. The scalar or tensor optical shifts can depend on the magnon energy levels within the first and second atomic states.

[0113] For example, metastable states of Group III atoms and alkaline earth or alkaline earth-like atoms may possess relatively large tensor offsets, whose angles relative to the applied magnetic field can be adjusted to result in a situation where the scalar and tensor offsets balance and give a zero or near-zero differential optical offset between the first and second atomic states. The angle θ can be adjusted by selecting the polarization of the emitted light. For example, when the emitted light is linearly polarized, the total degree of polarization α can be written as the scalar component α scalar and the tensor component α tensor The sum of:

[0114] α=α scalar +(3cos 2 θ-1)α tensor

[0115] By appropriately choosing θ, the polarization rates of the first and second atomic states can be chosen to be equal or nearly equal, corresponding to a zero or near-zero differential optical shift, and the motions of the atoms can be decoupled.

[0116] The light source may be configured to direct light to one or more optical modulators (OMs) configured to generate a plurality of optical trapping sites. For example, the optical trapping unit may include an OM 214 configured to generate a plurality of optical trapping sites. Figure 3A The optical capture unit may be depicted as including one OM, but the optical capture unit may include any number of OMs, such as at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more OMs, or at most about 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 OM. The OM may include one or more digital micromirror devices (DMDs). The OM may include one or more liquid crystal devices, such as one or more liquid crystal on silicon (LCoS) devices. The OM may include one or more spatial light modulators (SLMs). The OM may include one or more acousto-optic deflectors (AODs) or acousto-optic modulators (AOMs). The OM may include one or more electro-optic deflectors (EODs) or electro-optic modulators (EOMs).

[0117] The OM can be optically coupled to one or more optical elements to generate a regular array of optical trapping sites. For example, the OM can be optically coupled to an optical element 219, such as Figure 3A The optical element may include a lens or a microscope objective configured to redirect light from the OM to form a regular rectangular grid of optical trapping sites.

[0118] For example, Figure 3A As shown in , the OM can include an SLM, DMD or LCoS device. The SLM, DMD or LCoS device can be imaged onto the back focal plane of the microscope objective. This can allow the generation of arbitrary configurations of optical trapping sites in two or three dimensions.

[0119] Alternatively or in combination, the OM may include a first and a second AOD. The active regions of the first and second AODs may be imaged onto the back focal plane of the microscope objective. The output of the first AOD may be optically coupled to the input of the second AOD. In this way, the second AOD may make a copy of the light output of the first AOD. This may allow the generation of optical trapping sites in two or three dimensions.

[0120] Alternatively or in combination, the OM may include static optical elements, such as one or more microlens arrays or holographic optical elements. The static optical elements may be imaged onto the back focal plane of the microscope objective. This may allow the generation of arbitrary configurations of optical trapping sites in two or three dimensions.

[0121] The optical trapping unit may include one or more imaging units configured to obtain one or more images of the spatial configuration of the plurality of atoms trapped within the optical trapping site. For example, the optical trapping unit may include imaging unit 215. Figure 3A The optical capture unit may include any number of imaging units, such as at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more imaging units or at most about 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1 imaging units. The imaging unit may include one or more lenses or objective lenses. The imaging unit may include one or more PMTs, photodiodes, avalanche photodiodes, phototransistors, reverse biased LEDs, CCDs or CMOS cameras. The imaging unit may include one or more fluorescence detectors. The images may include one or more fluorescence images, single-atom fluorescence images, absorption images, single-atom absorption images, phase contrast images or single-atom phase contrast images.

[0122] The optical trapping unit may include one or more spatial configuration artificial intelligence (AI) units configured to perform one or more AI operations to determine the spatial configuration of the plurality of atoms trapped within the optical trapping site based on the image obtained by the imaging unit. For example, the optical trapping unit may include the spatial configuration AI unit 216. Figure 3A 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more spatially configured AI units or at most approximately 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 spatially configured AI unit. The AI ​​operations may include any machine learning (ML) or reinforcement learning (RL) operations described herein.

[0123] The optical trapping unit may include one or more atom rearrangement units configured to impart a changed spatial arrangement of the plurality of atoms trapped by the optical trapping site based on one or more images obtained by the imaging unit. For example, the optical trapping unit may include the atom rearrangement unit 217. Figure 3A The optical trapping unit is depicted as including a single atomic rearrangement unit, but the optical trapping unit may include any number of atomic rearrangement units, such as at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more atomic rearrangement units or at most about 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 atomic rearrangement unit.

[0124] The optical trapping unit may include one or more spatial arrangement artificial intelligence (AI) units configured to perform one or more AI operations to determine a changed spatial arrangement of the plurality of atoms trapped within the optical trapping site based on the image obtained by the imaging unit. For example, the optical trapping unit may include the spatial arrangement AI unit 218. Figure 3A The optical capture unit may include any number of spatially arranged AI units, such as at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more spatially arranged AI units or at most about 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 spatially arranged AI unit. The AI ​​operations may include any machine learning (ML) or reinforcement learning (RL) operations described herein.

[0125] In some cases, the spatial configuration AI unit and the spatial arrangement AI unit can be integrated into an integrated AI unit. The optical capture unit can include any number of integrated AI units, such as at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more integrated AI units, or at most about 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1 integrated AI unit.

[0126] The atom rearrangement unit can be configured to change the spatial arrangement so as to obtain an increase in the filling factor of the plurality of optical trapping sites. The filling factor can be defined as the ratio of the number of optical trapping sites occupied by one or more atoms to the total number of optical trapping sites available in the optical trapping unit or in the region of the optical trapping unit. For example, the initial loading of atoms within the optical trapping sites can cause a filling factor of less than 100%, 90%, 80%, 70%, 60%, 50% or less, so that the atoms occupy less than 100%, 90%, 70%, 60%, 50% or less of the available optical trapping sites, respectively. It may be desirable to rearrange the atoms to achieve a filling factor of at least about 50%, 60%, 70%, 80%, 90% or 100%. By analyzing the imaging information obtained by the imaging unit, the atomic rearrangement unit can obtain a filling factor of at least about 50%, 60%, 70%, 80%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.1%, 99.2%, 99.3%, 99.4%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.91%, 99.92%, 99.93%, 99.94%, 99.95%, 99.96%, 99.97%, 99.98%, 99.99% or more. The atomic rearrangement unit can obtain a filling factor of at most about 99.99%, 99.98%, 99.97%, 99.96%, 99.95%, 99.94%, 99.93%, 99.92%, 99.91%, 99.9%, 99.8%, 99.7%, 99.6%, 99.5%, 99.4%, 99.3%, 99.2%, 99.1%, 99%, 98%, 97%, 96%, 95%, 94%, 93%, 92%, 91%, 90%, 80%, 70%, 60%, 50% or less. The atomic rearrangement unit can obtain a filling factor within the range defined by any two of the aforementioned values.

[0127] For example, Figure 3C An example of an optical trapping cell partially filled with atoms is shown. Figure 3C As depicted in , the initial loading of atoms within the optical trapping sites can result in a filling factor of 44.4% (4 atoms filling 9 available optical trapping sites). Figure 3C Much higher filling factors can be achieved by moving atoms (not shown) to unoccupied optical trapping sites or by moving atoms from the atom reservoirs described herein, such as Figure 3D as shown in .

[0128] Figure 3D An example of an optical trapping cell completely filled with atoms is shown. Figure 3DAs depicted in FIG. 5 , the fifth atom 212e, the sixth atom 212f, the seventh atom 212g, the eighth atom 212h, and the ninth atom 212i can be moved to fill unoccupied optical trapping sites. The fifth, sixth, seventh, eighth, and ninth atoms can be moved from different regions of the optical trapping unit ( Figure 3C The optical trapping sites are arranged in a manner that allows the atoms to be moved (not shown) or by moving atoms from the atom reservoir described herein. Thus, after rearrangement of the atoms within the optical trapping sites, the filling factor can be significantly improved. For example, a filling factor of up to 100% can be obtained (such that 9 atoms fill 9 available optical trapping sites, e.g. Figure 3D ).

[0137] The electromagnetic delivery unit can be configured to apply one or more single qubit operations by inducing one or more Raman transitions between a first qubit state and a second qubit state as described herein. The Raman transitions can be from the first qubit state described herein to the second qubit state described herein. 3 P0 or 3 The P1 line can be detuned. For example, the Raman transition can be detuned by at least about 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, 200 MHz, 300 MHz, 400 MHz, 500 MHz, 600 MHz, 700 MHz, 800 MHz, 900 MHz, 1 GHz, or more. The Raman transitions may be detuned by up to about 1 GHz, 900 MHz, 800 MHz, 700 MHz, 600 MHz, 500 MHz, 400 MHz, 300 MHz, 200 MHz, 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, or less. The Raman transition may be detuned by a value within a range defined by any two of the aforementioned values.

[0138] One or more spatial light modulators (SLM) or acousto-optic deflectors (AOD) can be used to induce Raman transitions on individually selected atoms to impart a deflection angle and / or frequency shift to the light beam based on an applied radio frequency (RF) signal. The SLM or AOD can be combined with an optical adjustment system that images the SLM or AOD active area onto the rear focal plane of a microscope objective. The microscope objective can perform a spatial Fourier transform on the light field at the position of the SLM or AOD. In this way, an angle (which can be proportional to the RF frequency) can be converted into a position. For example, applying a radio frequency comb to an AOD can generate a linear array of light spots on the focal plane of the objective, each light spot having a limited range determined by the characteristics of the optical adjustment system (such as the point spread function of the optical adjustment system).

[0139] To perform a Raman transition on a single atom with a single SLM or AOD, a pair of frequencies can be applied simultaneously to the SLM or AOD. The two frequencies of the pair can have a frequency difference that matches or nearly matches the splitting energy between the first and second qubit states. For example, the frequency difference can differ from the splitting energy by at most approximately 1 MHz, 900kHz, 800kHz, 700kHz, 600kHz, 500kHz, 400kHz, 300kHz, 200kHz, 100kHz, 90kHz, 80kHz, 70kHz, 60kHz, 50kHz, 40kHz, 30kHz, 20kHz, 10kHz, 9kHz, 8kHz, 7kHz, 6kHz, 5kHz, 4kHz, 3kHz, 2kHz, 1kHz, 900Hz, 800Hz, 700Hz, 600Hz, 500Hz, 400Hz, 300Hz, 200Hz, 100Hz, 90Hz, 80Hz, 70Hz, 60Hz, 50Hz, 40Hz, 30Hz, 20Hz, 10Hz, 9Hz, 8Hz, 7Hz, 6Hz, 5Hz, 4Hz, 3Hz, 2Hz, 1Hz or less. The frequency difference may differ from the splitting energy by at least about 1 Hz, 2 Hz, 3 Hz, 4 Hz, 5 Hz, 6 Hz, 7 Hz, 8 Hz, 9 Hz, 10 Hz, 20 Hz, 30 Hz, 40 Hz, 50 Hz, 60 Hz, 70 Hz, 80 Hz, 90 Hz, 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 or more. The frequency difference may differ from the splitting energy by about 0 Hz. The frequency difference may differ from the splitting energy by a value within a range defined by any two of the foregoing values. The optical system may be configured such that the position interval corresponding to the frequency difference is not resolved and such that both frequencies of light interact with a single atom.

[0140] Integrated optical trapping unit and electromagnetic delivery unit

[0141] The optical trapping unit and the electromagnetic delivery unit described herein can be integrated into a single optical system. A microscope objective can be used to deliver the electromagnetic radiation generated by the electromagnetic delivery unit described herein and to deliver light for trapped atoms generated by the optical trapping unit described herein. Alternatively or in combination, different objective lenses can be used to deliver the electromagnetic radiation generated by the electromagnetic delivery unit and to deliver light from trapped atoms generated by the optical trapping unit.

[0142] A single SLM or AOD can allow qubit operations (such as any single qubit or double qubit operations described herein) to be implemented on a linear array of atoms. Alternatively or in combination, two separate SLMs or AODs can be configured to process light with orthogonal polarizations respectively. Light with orthogonal polarizations can be overlapped before the microscope objective. In such a scheme, each photon used in the two-photon transition described herein can be delivered to the objective lens by a separate SLM or AOD, which can allow improved polarization control. By introducing the light from the first SLM or AOD via an optical repeater into a second SLM or AOD oriented substantially orthogonal to the first SLM or AOD, qubit operations can be performed on the two-dimensional arrangement of atoms. Alternatively or in combination, by using a one-dimensional array of SLMs or AODs, qubit operations can be performed on the two-dimensional arrangement of atoms.

[0143] The stability of the qubit gate fidelity can be improved by maintaining an overlap of light from the various light sources described herein, such as light sources associated with the optical capture unit or electromagnetic delivery unit described herein. This overlap can be maintained by an optical subsystem that measures the direction of light emitted by the various light sources, allowing closed-loop control of the light emission direction. The optical subsystem can include a pickup mirror located in front of the microscope objective. The pickup mirror can be configured to direct a small amount of light to a lens that can focus a collimated light beam and convert angular deviations into positional deviations. A position-sensitive optical detector such as a lateral effect position sensor or a quadrant photodiode can convert the positional deviation into an electronic signal, and information about the deviation can be fed into a compensating optical device such as an active mirror.

[0144] The stability of the qubit gate operation can be improved by controlling the intensity of light from the various light sources described herein, such as light sources associated with the optical trapping unit or electromagnetic delivery unit described herein. This intensity control can be maintained by an optical subsystem that measures the intensity of light emitted by the various light sources, allowing closed-loop control of the intensity. Each light source can be coupled to an intensity actuator, such as an intensity servo control. The actuator can include an acousto-optic modulator (AOM) or an electro-optic modulator (EOM). The intensity can be measured using an optical detector, such as a photodiode or any other optical detector described herein. Information about the intensity can be integrated into a feedback loop to stabilize the intensity.

[0146] Figure 5 An example of a state preparation unit 250 is shown. The state preparation unit can be configured to prepare a state of a plurality of atoms, as described herein. The state preparation unit can be coupled to an optical trapping unit and can direct atoms that have been prepared by the state preparation unit to the optical trapping unit. The state preparation unit can be configured to cool a plurality of atoms. The state preparation unit can be configured to cool a plurality of atoms before trapping the plurality of atoms at a plurality of optical trapping sites.

[0147] The state preparation unit may include one or more Zeeman reducers. For example, the state preparation unit may include the Zeeman reducer 251. Figure 5 The state preparation unit is depicted as including a single Zeeman slowdown, but the state preparation unit can include any number of Zeeman slowdowns, such as at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more Zeeman slowdowns or at most about 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 Zeeman slowdown.

[0195] Example

[0196] In the following example, ten nuclear spin energy levels of strontium-87 (I=9 / 2) are modeled to demonstrate a 2-level system (i.e., a qubit). In order to achieve spectral isolation of qubit transitions, a Stark shift scheme is employed, which shifts unwanted transitions away from the qubit frequency. The isolation scheme can improve effective isolation with respect to achievable Rabi frequencies, can reduce the impact on the actual qubit state via shifts or residual scattering, can not require perfect polarization control, can be accessed with reasonable amounts of optical power, and so on. 1 S0 to 3 The properties of the P1 resonance can be characterized.

[0197] exist Fig. 10A In this paper, a toy model is used to demonstrate the shift of three related nuclear spin states: m F = 9 / 2 and 7 / 2 energy levels, which makes the qubit subspace and leakage energy levels 5 / 2. Here, the behavior of a single circularly polarized global AC Stark beam addressing an atomic array in a 700 Gauss magnetic field is simulated. In addition, a 100:1 polarization purity is assumed as well as the expected circular polarization. 1 S0 to 3 Each time the P1 resonance is detuned, each nuclear spin energy level experiences a shift. To further clarify, the qubit frequency (m F =9 / 2 and m F =7 / 2 modified energy) and leakage transition frequency (m F =7 / 2 and m F =5 / 2 The difference between the modified states) are plotted.

[0198] Fig. 10B It is shown that the Stark shift significantly shifts the leakage transition while having minimal effect on the qubit frequency. This is probably due to 3 The P1 resonance is achieved due to the narrow linewidth of the energy level splitting in high magnetic fields. Although the frequency is plotted as a signed quantity, subtleties associated with the quantization axes and light delivery make the absolute value of this frequency relevant, and hence the signature of the Stark shift pushing the leakage state very close to the qubit frequency. At each detuning, the maximum available Rabi frequency achievable given frequency crowding can be defined. Using this two-photon Rabi frequency, the pi pulse time can be inferred and the number of scattering events that occur due to off-resonant interactions of the AC Stark beam can be viewed ( Fig. 10A ).

[0199] No distinction is made here between Raman and Rayleigh scattering, and therefore a worst-case scenario for AC Stark-induced scattering errors is assumed for each gate. To perform single-qubit gates, the same 3 The two beams are detuned by P1 resonance to coherently control the light to drive the two-photon transition. Due to the 7kHz linewidth of the transition, 3 The residual scattering of the P1 manifold state may be inherently low. Including the effects of the AC Stark offset beam, 3 The expansion of the P1 hyperfine magnetic sublevel can be exploited to separate the energy scale between an AC Stark beam detuned from the F = 11 / 2 manifold and multiphoton 1Q light detuned from the F = 7 / 2 manifold. A simple toy model involving two ground states and a few excited states is sufficient to gain insight into the scaling of power, spot size, and achievable Rabi rates. However, due to the numerous energy levels involved ( 1S0(F=9 / 2), 3 P1 (F = 7 / 2, 9 / 2, 11 / 2)) (including all their magnon energy levels), so it may be necessary to perform full-scale simulations including all relevant energy levels. To verify full operation, a numerical model was built that uses all 40 energy levels and multiple light fields to represent the desired and undesired polarizations. Using simple square wave pulses, it can be seen that transitions to other nuclear spin states can be suppressed with an AC Stark beam ( Fig.11A and Fig. 11B ).

[0200] Fig. 12A and Fig. 12B The captured light arrays generated by the SLM in a square array and an arbitrary array are shown. The holograms are generated by reflecting 813 nm light from a spatial light modulator (SLM) ( 1 S0→ 3 The active area of ​​the SLM is a 1920x1152 square array of pixels with sides of about 9 microns. Each pixel contains a volume of liquid crystal that imparts a phase shift to the incident light. This phase shift can be controlled by a voltage applied to the pixel, and in this way, an arbitrary, pixelated phase mask can be generated and applied to any unstructured light incident on the surface of the SLM. The SLM is positioned in such a way that a large collimated beam is incident and phase shifted; the light reflected from the SLM is then directed through the microscope objective. This configuration connects the plane of the SLM to the plane below the lens (where the atomic cloud is formed) via Fourier conjugation. The complex-valued in-plane electric field at the SLM is the Fourier transform of a similar field in the volume of the glass cell, in the plane below the microscope objective. The atoms experience a trapping potential proportional to the strength of the electric field, and therefore experience lateral confinement. Longitudinal confinement comes from structured light passing through the focus, whose position is also partially determined by (and therefore controlled by) the SLM.

[0201] Two thousand traps were created, each 500 microkelvin deep, to give a recoil energy more than 1,000 times greater than that imparted by a scattered photon, for imaging or other purposes. This means that the device should be well within the range where atoms can be measured hundreds of times without being lost due to heating, even without additional cooling. Cooled to their motional ground state, the positions of atoms are known to within 20 nanometers, which allows for significant separation in scale between the positions of atoms and the size of the laser beams used to drive single- and two-qubit gates, or the length scale of the Rydberg interaction. The laser beams driving the gate operations will have a spatial extent on the order of micrometers, and will therefore have intensities on the order of 10 -5 energy levels change; therefore, a fidelity of 0.9999 is expected to be easily achievable. In this way, the gate fidelity is less sensitive to the position of the atoms.
