[0002] A quantum computer is a machine that can perform quantum computing. It uses the laws of quantum mechanics to perform mathematical and logical operations, and process and store information. When a quantum computer performs computing tasks, it is necessary to regularly control the quantum computer to execute a specific monitoring quantum algorithm to measure the quantum bits of the quantum computer, obtain the performance indicators of the quantum computing system based on the measurement results, and analyze whether errors have occurred.

[0003] However, it relies on regular measurements of the quantum computer's quantum bits, and is unable to obtain performance indicators during the execution of specific monitoring quantum algorithms. In addition, it is unable to interrupt tasks to execute specific monitoring quantum algorithms during the execution of other computing tasks, and is unable to obtain feedback on the performance of the quantum computer system during the execution of other computing tasks, making it impossible to achieve real-time monitoring of the quantum computer.

[0047] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0048] The present disclosure is described in detail below with reference to specific embodiments.

[0049] In the first embodiment, if Figure 1 As shown, Figure 1 This is a flow chart of a method for monitoring the performance of a quantum computer provided by an embodiment of the present disclosure. The method can be implemented by a computer program and can be run on a device for monitoring the performance of a quantum computer. The computer program can be integrated into an application or run as an independent tool application.

[0050] Among them, the quantum computer performance monitoring device can be an electronic device with a quantum computer performance monitoring function, and the electronic device can be a quantum computer or a device that monitors the performance of a quantum computer.

[0051] Among them, the quantum computer performance monitoring method can be executed by an electronic device.

[0052] For example, the quantum computer performance monitoring method includes the following steps:

[0053] S101, obtaining a quantum task to be executed input into the quantum computer, and establishing quantum entanglement between the computing quantum bit and the monitoring quantum bit in a target quantum entanglement mode;

[0054] According to some embodiments, the quantum task to be performed refers to a quantum computing task that needs to be performed by a quantum computer.

[0055] In some embodiments, a computational qubit refers to a qubit in a quantum computer that is used to perform a quantum task to be performed.

[0056] According to some embodiments, the target quantum entanglement mode refers to the entanglement mode when the computing quantum bit and the monitoring quantum bit are quantum entangled. The target quantum entanglement mode can be determined by the quantum task to be performed.

[0057] In some embodiments, when the monitoring qubit and the computing qubit are in a quantum entangled state, the qubit state of the monitoring qubit will change with the change of the computing qubit. For example, the qubit state of the monitoring qubit may change due to the influence of the error type, error rate, fidelity, etc. of the computing qubit. Therefore, the monitoring qubit can be used to monitor the computing qubit. The monitoring qubit may be a qubit in a quantum computer or may not be a qubit in a quantum computer.

[0059] S103, based on quantum entanglement, determining the performance operating indicators of the quantum computer according to the measurement results.

[0060] In summary, the method provided in this embodiment is not bound by the inherent mindset of ordinary technicians in this field, that is, monitoring a system requires monitoring the system itself, but by establishing quantum entanglement between the computing qubit and the monitoring qubit in a target quantum entanglement mode, and utilizing the characteristics of quantum entanglement, the qubit state of the monitoring qubit is affected by the qubit state of the computing qubit. By indirectly monitoring the computing qubit through the monitoring qubit, there is no need to measure the computing qubit, thereby fundamentally avoiding the influence on the qubit state of the computing qubit, thereby realizing non-disturbance monitoring of the performance of the quantum computer; secondly, the performance operating indicators of the quantum computer can be given during the execution of the quantum task, and the execution of the quantum task does not need to be interrupted, so that real-time monitoring of the performance of the quantum computer can be realized.

[0061] This embodiment also provides another method for monitoring the performance of a quantum computer, which can be executed by an electronic device.

[0062] For example, the quantum computer performance monitoring method may include the following steps:

[0063] S201, initializing the quantum computer;

[0064] It should be noted that by initializing the quantum computer, the impact of the historical performance monitoring process of the quantum computer on the current performance monitoring can be reduced, and the accuracy of the performance monitoring of the quantum computer can be improved.

[0065] S202, obtaining an initial quantum task to be executed input into the quantum computer, and mapping the initial quantum task to be executed into a quantum task to be executed that can be executed by the quantum computer;

[0066] According to some embodiments, the quantum task to be executed may be, for example, a quantum algorithm executable by computing quantum bits in a quantum computer.

[0067] In some embodiments, the quantum task to be executed can be input into a quantum operating system of a computing quantum bit, so that the quantum operating system controls the computing quantum bit to execute the quantum task to be executed.

[0068] It should be noted that by obtaining the initial quantum task to be executed as input to the quantum computer and mapping the initial quantum task to be executed to a quantum task to be executed that can be executed by the quantum computer, the situation where the quantum computer cannot execute the quantum task to be executed can be reduced.

[0069] S203, obtaining a quantum task to be executed input to the quantum computer, and determining a target quantum entanglement mode between a computing quantum bit and a monitoring quantum bit according to bit gate information and execution circuit information corresponding to the quantum task to be executed;

[0070] According to some embodiments, the bit gate information includes but is not limited to the number and type of single-bit gates, two-bit gates, and multi-bit gates.

[0071] In some embodiments, the execution line information includes but is not limited to the execution line depth, etc.

[0072] In some embodiments, the target quantum entanglement mode includes but is not limited to the type and method of quantum entanglement. The type of quantum entanglement includes but is not limited to the type of quantum gate used to establish entanglement, and the method of quantum entanglement includes but is not limited to one-to-many entanglement, many-to-many entanglement, etc.

[0073] It should be noted that by determining the target quantum entanglement mode between the computing quantum bit and the monitoring quantum bit according to the bit gate information and the execution circuit information corresponding to the quantum task to be executed, the accuracy of determining the target quantum entanglement mode can be improved.

[0074] S204, establishing quantum entanglement between the computing quantum bit and the monitoring quantum bit in a target quantum entanglement mode;

[0075] S205, in the process of the computing qubit executing the quantum task to be executed, measuring the qubit state of any monitoring qubit subset in the monitoring qubit set to obtain a measurement result, setting any monitoring qubit subset as a detected monitoring qubit subset, and re-establishing quantum entanglement between the detected monitoring qubit subset and the computing qubit in a target quantum entanglement mode;

[0076] According to some embodiments, the monitoring qubit set includes a plurality of monitoring qubit subsets, each monitoring qubit subset includes at least one monitoring qubit, and there is quantum entanglement between the monitoring qubit subset and the computational qubit in a target quantum entanglement mode.

[0077] In some embodiments, after measuring the quantum bit state of the monitoring quantum bit subset, the monitoring quantum bit subset will undergo a change in quantum state, that is, there is no quantum entanglement between the detected monitoring quantum bit subset and the computing quantum bit in the target quantum entanglement mode. Therefore, it is necessary to re-prepare the entangled state of the detected monitoring quantum bit subset and the computing quantum bit, that is, to re-establish quantum entanglement between the detected monitoring quantum bit subset and the computing quantum bit in the target quantum entanglement mode, thereby converting the detected monitoring quantum bit subset into a monitoring quantum bit subset.

[0078] In some embodiments, after measuring the qubit state of any monitoring qubit subset in the monitoring qubit set, another monitoring qubit subset may be measured to achieve real-time monitoring of quantum computer performance.

[0079] According to some embodiments, when measuring the quantum bit state of the monitoring quantum bit, the measurement method includes but is not limited to quantum projection measurement and the like.

[0080] S206, performing data analysis on the measurement results to obtain a first performance indicator corresponding to the monitoring quantum bit;

[0081] According to some embodiments, the first performance indicator refers to a performance indicator corresponding to the monitored quantum bit.

[0082] In some embodiments, performance indicators include but are not limited to error type, error rate, fidelity, etc.

[0083] S207, based on quantum entanglement, determining a second performance indicator corresponding to the calculation quantum bit according to the first performance indicator;

[0084] According to some embodiments, the second performance indicator refers to a performance indicator corresponding to a calculation quantum bit.

[0085] S208, determining a performance operating indicator of the quantum computer according to the second performance indicator.

[0086] According to some embodiments, the second performance indicator may be directly used as a performance operation indicator of the quantum computer, for example.

[0087] It should be noted that by utilizing the characteristics of quantum entanglement, the qubit state of the monitoring qubit is affected by the qubit state of the computing qubit. Therefore, the computing qubit can be indirectly monitored by the monitoring qubit, and the second performance indicator corresponding to the computing qubit can be indirectly obtained by the first performance indicator corresponding to the monitoring qubit, thereby determining the performance operating indicator of the quantum computer.

[0088] In order to implement the above embodiments, the present disclosure also proposes a quantum computer performance monitoring device.

[0089] For example, Figure 2 A schematic diagram of the structure of a quantum computer performance monitoring device provided in an embodiment of the present disclosure.

[0091] A computing quantum bit module is used to obtain the quantum task to be executed which is input into the quantum computer;

[0092] A monitoring qubit module, used to establish quantum entanglement between a computing qubit and a monitoring qubit in a target quantum entanglement mode, wherein the target quantum entanglement mode is determined by the quantum task to be performed, the computing qubit is a qubit in a quantum computer used to perform the quantum task to be performed, and the monitoring qubit is used to monitor the computing qubit;

[0093] A non-destructive measurement module is used to measure the quantum bit state of the monitoring quantum bit during the process of the computing quantum bit performing the quantum task to be performed, and obtain a measurement result;

[0094] The indicator calculation output module is used to determine the performance operating indicators of the quantum computer based on the measurement results based on quantum entanglement.

[0095] It should be noted that the aforementioned explanation of the embodiment of the quantum computer performance monitoring method is also applicable to the quantum computer performance monitoring device of this embodiment, and will not be repeated here.

[0096] The computing qubit module is located in the quantum computer and includes computing qubits in the quantum computer. When the computing qubit module is used to perform a quantum computing task, the computing qubits in the computing qubit module perform the quantum computing task.

[0097] Among them, when quantum entanglement is established between the computing quantum bit and the monitoring quantum bit in the target quantum entanglement mode, it can also be understood as establishing quantum entanglement between the computing quantum bit module and the monitoring quantum bit module in the target quantum entanglement mode.

[0098] Among them, since the monitoring quantum bit and the computing quantum bit are in an entangled state, the non-destructive measurement module will not affect the state of the computing quantum bit during the measurement process. In other words, the non-destructive measurement module can perform non-destructive measurement on the quantum bit state of the monitoring quantum bit module to obtain the quantum bit state of the monitoring quantum bit.

[0099] Among them, the indicator calculation output module can be used to analyze the measurement results of the non-destructive measurement module, calculate and output the real-time, non-disturbance performance indicators of the quantum computer operation.

[0100] Take a scenario as an example. Figure 3 This is a flowchart of a quantum computer performance monitoring device provided by an embodiment of the present disclosure. Figure 3 As shown, when the quantum computer performance monitoring device executes the quantum computer performance monitoring method, the following steps are included:

[0102] S2, the computing quantum bit module executes the mapping quantum algorithm and inputs it, wherein the computing quantum bit module can map the initial quantum task into a quantum algorithm executable by the computing quantum bit module, and input the quantum algorithm into the quantum operating system of the computing quantum bit;

[0103] S3, the calculation quantum bit module performs quantum entanglement method calculation, wherein the calculation quantum bit module can calculate the type and method of establishing quantum entanglement between the monitoring quantum bit module and the calculation quantum bit module according to the mapped quantum algorithm, that is, the target quantum entanglement mode;

[0104] S4, the monitoring quantum bit module executes quantum entanglement establishment, wherein the monitoring quantum bit module can establish quantum entanglement between the monitoring quantum bit module and the computing quantum bit module according to the target quantum entanglement mode;

[0105] S5, the computational qubit module executes the quantum algorithm;

[0106] S6, the monitoring qubit module and the non-destructive measurement module perform monitoring qubit measurement, wherein the non-destructive measurement module can measure the qubit state of any monitoring qubit subset in the monitoring qubit module, and output the measurement result to the indicator calculation output module;

[0107] S7, the indicator calculation output module performs performance indicator calculation and outputs, wherein the indicator calculation output module can analyze the measurement results input by the non-destructive measurement module and calculate the performance operation indicator of the quantum computer;

[0108] S8, after measuring the quantum bit state of any monitoring quantum bit subset in the monitoring quantum bit module in S5, measuring another monitoring quantum bit subset to achieve real-time monitoring of quantum computer performance;

[0109] S9, while S7 is being executed, re-preparing the detected monitoring quantum bit subset to an entangled state with the computing quantum bit;

[0110] S10, repeat S5 to S8 until the quantum algorithm in S5 is executed.

[0111] In summary, the device provided by the embodiments of the present disclosure is not bound by the inherent mindset of ordinary technicians in the field, that is, monitoring a system requires monitoring the system itself, but rather establishes quantum entanglement between the computing qubit and the monitoring qubit in a target quantum entanglement mode, and utilizes the characteristics of quantum entanglement to make the qubit state of the monitoring qubit affected by the qubit state of the computing qubit. By indirectly monitoring the computing qubit through the monitoring qubit, there is no need to measure the computing qubit, thereby fundamentally avoiding the influence on the qubit state of the computing qubit, thereby achieving non-disturbance monitoring of the performance of the quantum computer; secondly, the performance operating indicators of the quantum computer can be given during the execution of the quantum task, and the execution of the quantum task does not need to be interrupted, so that real-time monitoring of the performance of the quantum computer can be achieved.
