Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 63 / 306,261, filed February 3, 2022, the entire contents of which are incorporated by reference herein for all purposes.

[0002] Embodiments of the present disclosure generally relate to quantum computing systems that include an integrated servo system or apparatus for controlling quantum computing operations. [Background technology]

[0003] Quantum computers require numerous subsystems / components, including electronic devices, optical devices, sensors, mechanical devices, and controllers (e.g., for temperature control). Such subsystems / components must be precisely controlled and coordinated to perform quantum computations, such as by performing multiple quantum operations. For example, in various atomic systems, the execution of quantum operations is critical to be able to deliver a laser beam to the system at a specific position, frequency, phase, and / or time to complete various functions, such as implementing logic gates. Subsystems / components often generate noise that is detrimental to the operation of quantum computers. Conventional subsystems / components may also take longer to execute, which may be detrimental to the execution of quantum operations by causing atomic objects used as quantum bits to go from a desired state to an undesired state.

[0004] Quantum computers are expected to have raised demands with respect to tighter tolerances for noise and timing, etc. Current industry practice is to use a large number of separate servo systems / units for closed-loop control of subsystems / components. There are limitations to using separate servos, which are impractical for performance reasons, including generated noise, volume, size, timing, and challenges with integrating with other components for closed-loop control. As described herein, applicants have found problems with current implementations of quantum computing systems, including problems with separate servos. Through hard work, ingenuity, and innovation, applicants have solved many of these identified problems in various implementations and approaches embodied in this disclosure, which are described in detail below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The embodiments of the present disclosure will now be described more fully with reference to the accompanying drawings, in which some, but not all, embodiments of the present disclosure are shown. Indeed, the embodiments of the present disclosure may be embodied in many different forms and should not be considered as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will satisfy applicable legal requirements. The term "or" (also written as " / ") is used herein in both the alternative and conjunctive sense, unless otherwise indicated. The terms "exemplary" and "exemplary" are used as examples without indicating a level of quality. The terms "generally," "substantially," and "approximately" refer to within processing and / or manufacturing tolerances and / or within the measurement capabilities of the user, unless otherwise indicated. Like reference numbers in the drawings refer to like elements throughout.

[0024] Those skilled in the art to which this disclosure pertains, having the benefit of the teachings presented in the foregoing description and the associated drawings, will envision many modifications and other embodiments of the disclosure described herein. Accordingly, it should be understood that the embodiments are not to be limited to the specific embodiments disclosed, and that modifications and other embodiments are intended to be included within the scope of the appended claims. Moreover, while the foregoing description and the associated drawings describe exemplary embodiments in the context of certain illustrative combinations of elements and / or functions, it should be understood that different combinations of elements and / or functions may be provided by alternative embodiments without departing from the scope of the appended claims. In this regard, combinations of elements and / or functions different from those expressly described above are also contemplated, for example, as may be recited in some of the appended claims.

[0025] Overview Quantum computing systems, such as QCCD ion trap quantum computers, manipulate qubits for use in various computing activities. The term "QCCD" refers to a quantum charge coupled device architecture that allows for the storage and placement of qubits via a number of operations. Qubits in a QCCD are moved (e.g., via gating) to specific locations on the chip to perform quantum operations. An exemplary QCCD architecture uses very small objects confined in a very small object confinement device as qubits, such as ions trapped in an ion trap.

[0026] A quantum computer may utilize qubits as inputs to logic gates that are configured to perform logical operations based on the state of the input qubits. For example, the configurations of logic gates may be combined in a myriad of ways in a quantum program, if the quantum program is specifically configured to reach a desired result. The terms "quantum program" and "quantum circuit" refer to any number of gating operations to be performed utilizing one or more qubits in a quantum computer system. A quantum program may include any number of gating operations performed on one or more qubits in a quantum computing environment. Each "gate," "logic gate," "gating operation," "gating operation," or "operation" of a quantum program involves a single qubit or a qubit group of two or more qubits. The quantum operations are controlled by subsystems and components of the quantum computer, including a servo system.

[0027] Quantum computer systems perform quantum computations by executing quantum programs written by a user or operator. These programs are often written in a high-level language that describes how to manipulate qubits. The high-level programs are decomposed into many lower-level operations for various devices (instruments, electronics, optics, and mechanical devices) that manipulate the qubits to perform the desired quantum computation. These operations must be very precise and coordinated with each other. The system that coordinates these operations may be a "controller," which may include or control multiple servo systems.

[0028] Quantum computer systems may be constrained by the use of separate servo systems due to noise and slower response introduced by separate servo systems. In various embodiments herein, the servo systems are integrated into the quantum computer's controller (e.g., an integrated servo system). In various embodiments, the controller includes multiple tightly integrated servo systems that are highly customizable to optimize the execution of quantum operations for quantum computing.

[0029] In various embodiments, the integrated servo system may share one or more components (e.g., filters, amplifiers, mixers, splitters, baluns, local oscillators, etc.) In various embodiments, the integrated servo system may cooperate with one or more separate servo systems.

[0030] Additionally or alternatively, through the improvements described herein, some embodiments of the present disclosure may enable a quantum computer system to solve larger and / or more complex problems due to, among other things, the aforementioned ability to execute quantum programs with less noise and greater responsiveness and control over the quantum operations performed by the quantum computer system.

[0068] FIG. 4 provides a schematic diagram of an exemplary closed-loop control system that may be used according to certain exemplary embodiments. The closed-loop control system may consist of one or more components of other systems or subsystems of the quantum computing system 100. In various embodiments, the integrated servo system 217 may be used to control the laser beam intensity for the ion trap computing system 100 to provide the specific laser beam intensity profile required to effect the execution of a quantum operation. Causing the evolution of the quantum state of the qubit according to a quantum program may require a specific intensity profile with specific pulses having specific shapes at specific times. An ion trap quantum computer may use a laser, such as from the manipulation source 60, to manipulate the qubit and control the motional state of the qubit. There are many challenges for such lasers that a separate servo system cannot satisfy, including reducing noise as well as providing a precise, dynamically controlled intensity profile to manipulate and control the qubit during one or more quantum operations of a quantum program.

[0069] In various embodiments, the controller 30 may coordinate adjustments to the laser intensity profile using sensors including electro-optical devices (e.g., photodetectors) in a closed-loop control system. In various examples, the execution of the quantum program may result in fluctuations in noise (e.g., electrical noise, thermal noise, mechanical noise, etc.) that create fluctuations in the intensity of the laser. The output voltage of the sensor changes as electrical, thermal, and mechanical noise sources affect the system. In various embodiments, noise in the intensity of the laser may cause operational errors during the execution of the quantum program.

[0070] In various embodiments, the computing entity 10 may provide the quantum program to the controller 30. The controller 30 may include a control system housing 410. The control system housing 410 may include one or more FPGA printed circuit boards (PCBs) 420, and each FPGA PCB may include one or more FPGAs 430. Although FIG. 4 shows one control system housing 410, one FPGA 420, and one FPGA 430, it will be understood that various embodiments may include more than one of each.

The servo channel may include one or more channel components for conditioning, filtering, and / or modifying a signal. The servo channel may include one or more inputs and / or outputs for sending control signals between one or more components of the closed-loop control system. The closed-loop control system of FIG. 4 includes the following components: a laser source 440, an acousto-optic modulator (AOM) 450, an optical element 460 (e.g., mirrors, lenses, splitters, etc.), and a sensor 470 (e.g., photodetector). Also illustrated in FIG. 4 are an FPGA output signal (e.g., control signal) 432, a laser output 442, a modulated laser output 444, and a sensor output signal (e.g., control signal) 472. In various embodiments, the control signals (e.g., FPGA output signal 432 and sensor output 472) may be modified by one or more electrical components (e.g., filters, amplifiers, mixers, splitters, baluns, etc.), which may be located on the FPGA 430, on the FPGA PCB 420 (e.g., in a servo channel), or may be separate components located away from the FPGA PCB 420.

[0072] The FPGA output signal 432 may be an analog signal or a digital signal. The FPGA output signal 432 is an input in the AOM 450 to modulate the laser output 442. After the laser output 442 (e.g., a laser beam) is modulated in the AOM 450, the modulated laser output 444 is input to the optical element 460. In various embodiments, the optical element 460 may diffract a small portion of the modulated laser output 444 to the sensor 470 while directing the remainder to the quantum processor 115. The sensor 470 may be a photodetector that generates a sensor output signal 470 of a voltage upon receiving the diffracted amount of the modulated laser output 444. The sensor output signal 470 may be input to the FPGA 430. In various embodiments, this creates a closed loop control system such that the control signal 432 is output by the FPGA 430, the control signal 472 is received by the FPGA 430, and the FPGA 430 is configured to modify the control signal 432 based on the control signal 472.

Each of the independent control systems may be associated with a respective integrated servo system 217 that may be used to control and modify the output of the laser source 440 as described herein. In various embodiments, each independent control system may be associated with a unique FPGA PCB 420 and FPGA 430. Alternatively and / or additionally, two or more of the independent control systems may share the FPGA PCB 420 and / or FPGA 430. For example, the FPGA 430 may include only one integrated servo system 217 or may include more than one integrated servo system 217. In various embodiments, each of the independent control systems may operate independently. Additionally or alternatively, each of the independent control systems (e.g., a first independent control system) may operate in combination and / or simultaneously with one or more other independent control systems (e.g., a second independent control system) of the plurality of independent control systems. In various embodiments, each of the independent control systems (e.g., a first independent control system) may utilize only distinct components from the other independent control systems (e.g., a second independent control system), such that each independent control system is utilized in parallel. Alternatively and / or additionally, one or more of the independent control systems (e.g., a third independent control system) may utilize one or more components of another independent control system (e.g., a fourth independent control system).

[0078] In various embodiments, the FPGA 430 may comprise one or more DDS, one or more analog-to-digital converters (ADC), digital-to-analog converters (DAC), baluns, VGAs, AMs, amplifiers, mixers, splitters, and other components.

Additionally or alternatively, the FPGA 430 may include a compiler that compiles code and / or programs from a user into machine-executable instructions. Additionally and / or alternatively, the FPGA 430 may be configured with an analytical engine and / or a real-time engine.

[0079] In various embodiments, the analysis engine may include circuitry configured to analyze one or more control signals (e.g., 472), such as monitoring one or more sensors, such as sensors of a closed loop control system, and quantifying and classifying noise that may be indicated by fluctuations in the control signals 472. In various embodiments, the analysis engine may perform frequency analysis and / or execute signal analysis algorithms, such as algorithms that may indicate frequency content as specific times related to one or more portions of a quantum program (e.g., portions related to gate pulses and / or quantum operations) and / or algorithms related to analyzing noise during events related to the quantum computing system but not directly related to the integrated servo system 217 (e.g., a temperature rise due to a failure of a system component (e.g., an HVAC unit)). In various examples, the control signal may be analyzed for its frequency content. In various embodiments, the analysis engine may classify noise as passive noise and / or active noise. Passive noise may be noise in a system and / or components when no operations are being performed, which may vary with time, temperature, number of components, etc. Active noise may be noise in a system during the execution of operations. The analysis engine may be associated with or in communication with one or more memories and / or databases to store past analyses over time and generate historical trends related to monitoring and analyzing control signals from one or more sensors. In various embodiments, a determination from the past trends may indicate that one or more components need to be replaced or that an adaptive filter needs to be adjusted or optimized. In various embodiments, the analysis engine may create a data object including measurements related to the integrated servo system 217 for communication, for example, to the controller 30, which may include culling larger files into smaller files with specific data samples.

[0080] The analytical engine may cooperate with the controller 30 to adjust the FPGA output signal 432 for controlling the AOM 450 to perform quantum operations, such as by removing noise from the laser output 442, so that a modulated laser output 444 may be provided to the quantum processor 115 within the tolerances (e.g., amplitude tolerances) required to perform the quantum operations in accordance with the quantum program.

Additionally, the real-time engine may determine and execute adjustments (e.g., adjustments to the timing of execution) to synchronize hardware to cause execution of quantum operations as needed. In various embodiments, the real-time engine may monitor and communicate real-time measures regarding the performance of the integrated servo system 217. In various embodiments, the real-time engine may also make adjustments to control algorithms for one or more other components of the integrated servo system 217. Additionally and / or alternatively, the real-time engine may provide operational insights, including parameters, measurements, and feedback, that may be communicated to the controller 30 and / or computing entity 10. In various embodiments, such operational insights may include diagnostic data, which may indicate performance data for one or more components, fault data for one or more components, etc.

[0082] In various embodiments, the integrated servo system 217 may incorporate signal processing and / or logic from other components of the quantum computing system 100, including but not limited to components external to the closed-loop control system associated with the integrated servo system 217, such as with an analytics engine and / or a real-time engine, any of which may be used to dynamically or programmatically adjust the FPGA output 432 of the integrated servo system 217. In one example, such components may include environmental control equipment (e.g., HVAC) that may be associated with cooling a control enclosure 410 in which the integrated servo system 217 may be located, and operation (or failure of operation) of the HVAC may positively or negatively affect the amount of noise in the integrated servo system 217 and / or associated closed-loop control system components.

[0086] In various embodiments, the modulated laser output 444 may be controlled by the integrated servo system 217, such as with the FPGA output 432. The modulated laser output 444 may be controlled such that it has a particular laser intensity profile to perform a particular quantum operation when provided to the quantum processor 115, such as that shown in FIG. 5. In various embodiments, performing a particular quantum operation, such as during gating, requires exposing the ions to a pulse of laser light with a precisely defined profile that may include a particular shape, amplitude, and / or time length. The integrated servo system 217 may incorporate feedback (e.g., sensor output 472 from the sensor 470) to create a closed loop control system to adjust and / or steer the pulse and compensate for noise and / or nonlinear responses of components. The closed control loop may also be calibrated to remove noise and / or correct for nonlinear responses of components, such as the response of the AOM 450. In various embodiments, this may be necessary for gating operations that require laser pulses of widely different intensity levels for short periods of time, such as those in FIG. 5.

[0087] FIG. 5 includes rectangular pulse sets 510A, 510B and a shaped pulse set 520. The rectangular pulse sets 510A, 510B may include one or more rectangular pulses (FIG. 5 shows each 510A and 510B with four rectangular pulses). In various embodiments, the rectangular pulse sets 510A, 510B may be examples of wrapper pulse sets when such rectangular pulse sets 510A, 510B are on either side of another pulse set (e.g., shaped pulse set 520). The shaped pulses may include one or more shaped pulses (FIG. 5 shows two shaped pulses). The shaped pulses may be limited to a maximum amplitude, which may flatten the peak of the shaped pulse for a period of time, which may be the maximum amplitude. By controlling the intensity profile of the laser light (e.g., pulses) provided to the quantum processor 115, the fidelity of gates (e.g., one-qubit gates, two-qubit gates, etc.) may be improved and / or even enabled, where operations required by the quantum program require faster response times of particular quantum operations and / or particular ordering of quantum operations.

[0101] Example Process Having described an exemplary system and device architecture in accordance with the present disclosure, an exemplary process in accordance with the present disclosure is described below. It should be understood that the process illustrated in each of the following figures may be embodied in any number of ways.

[0102] FIG. 7 provides a first example process for a closed loop control system, according to at least some example embodiments of the present disclosure.

[0103] In operation 710, the integrated servo system 217 receives the program. In various embodiments, the program may be received from the computing entity 10, the controller 30, the servo GUI 620, the command line interface 632, and / or the operator interface 634. In various embodiments, the program may be received at the FPGA 430. The program may be a quantum program or a portion of a quantum program specific to the integrated servo system 217.

[0104] In operation 720, the integrated servo system 217 generates settings. In various embodiments, the FPGA 430 of the integrated servo system 217 may convert the portion of the received program into specific settings for the components associated with the integrated servo system 217. Such settings may include, but are not limited to, gain, phase, filter settings, transfer functions, etc., that may be used by the integrated servo system 217 during execution of one or more operations. In various embodiments, such as where the quantum program 217 may include multiple operations for the integrated servo system 217, multiple settings may be generated, which may include when the settings should be applied at a particular time to execute the multiple operations of the program. In various embodiments, data indicative of the settings may be stored in a database, such as the servo configuration database 650, which may store the data along with an indicator designating the program or portion of the program received in 710.

[0105] In operation 730, the integrated servo system 217 loads the configuration. In various embodiments, loading the configuration may include loading and / or adjusting a configuration that was generated for execution of operations at a particular time period corresponding to some or all of the program. In various embodiments, the configuration may be loaded into FPGA memory for use during execution of operations by the program.

[0106] At operation 740, the integrated servo system 217 receives feedback. In various embodiments, the feedback is received, such as at the FPGA 430, as operations occur and a controller of the closed-loop control system generates feedback. The feedback may be generated by one or more sensors associated with the closed-loop control system. Additionally or alternatively, feedback may be generated by components of the quantum computer system 100 not associated with the integrated servo system 217, which may be used as input for use in analyzing feedback associated with the integrated servo system 217.

[0107] In operation 750, the integrated servo system 217 analyzes the feedback. In various embodiments, the feedback from sensors associated with the integrated servo system 217 may be used to determine whether adjustments to settings are necessary. In various embodiments, the adjustments to settings may be to remove noise from one or more components associated with the integrated servo control system 217.

[0108] In operation 760, integrated servo system 217 generates an adjustment. In various embodiments, if the analysis of the feedback determines that an adjustment may need to be made, the adjustment may be generated by integrated servo system 217 and / or an operator. In various embodiments, integrated servo system 217 may be configured to dynamically generate the adjustment, which may be based on control signals (e.g., 472) received as feedback from sensors (e.g., 470). Additionally or alternatively, adjustment suggestions may be provided to an operator in an interface (e.g., 620, 632, 634), who may input an adjustment or select an adjustment from one or more lists, which may provide the adjustment to integrated servo system 217, or may provide an indication of the adjustment, which may then generate the adjustment. In various embodiments, if it is determined in operation 750 that no adjustment is needed, the operation may be performed by quantum computer system 100 without generating an adjustment in operation 760.

[0109] In an exemplary embodiment, the process of FIG. 7 may be utilized to calibrate the integrated servo system 217. A user may provide a program or command to calibrate the integrated servo system 217, such as executing a calibration routine, which is received by the integrated servo system 217. Alternatively, the controller 30 or the integrated servo system 217 may determine to perform a calibration if it determines that a monitored component of the integrated servo system 217, a component of the closed loop control system, or an external signal is found to generate an error or be outside of an acceptable error range, or if a certain amount of time has passed since the last calibration. The calibration routine may be to determine noise and response in a system component associated with the integrated servo system 217, such as the AOM 450. The integrated servo system 217 may generate one or more settings associated with the calibration routine that may be loaded into the components of the integrated servo system 217 (e.g., DDS, mixer, splitter, etc.). The calibration routine may then be executed, which includes the laser 440 generating a laser output 442 to be shaped by the AOM 450. The FPGA 430 may output an FPGA output signal 432, which may be generated based on the loaded settings. Execution of the operation may cause the sensor 470 to generate a sensor output signal 472 indicative of the noise and nonlinear response of the AOM during pulse shaping, which may be received by the FPGA 430. The FPGA 430 may analyze feedback of the sensor output signal 472 to determine adjustments to adjust the settings to make the AOM less noisy and behave with a linear response. The analysis may include generating multiple adjustments to be iteratively applied to calibrate the integrated servo system 217 and the AOM 450 to generate a desired intensity profile including pulse shape. The adjustments may be used to generate settings that are iteratively loaded. For each iteration, the FPGA 430 may use feedback of the sensor output signal 472 to dynamically adjust the settings, such as to compensate for thermal or mechanical noise associated with the iteration.

[0110] In an alternative exemplary embodiment, transfer functions associated with components of the closed loop control system may be determined and the associated integrated servo system 217 may be calibrated. The AOM 450 may be known to have a nonlinear response or may be determined to have a nonlinear response, such as with measurements of increasing output based on increasing input. The sensor output signal 472 may be measured with increasing input to the AOM 450, which may also include decreasing the input to account for hysteresis, etc. The integrated servo system 217 may determine, using a real-time engine and / or an analytical engine, etc., that the AOM 450 has a nonlinear response and determine a number of FPGA output signals 432 that cause the AOM 450 to provide a linear response.
