[0048] To solve the problems in the related art, an embodiment of the present application provides a synchronous triggering method. As Figure 1 shown, Figure 1 is a flowchart of the synchronous triggering method provided by the embodiment of the present application. A plurality of routing boards, a central control board, and function boards constitute a quantum computing measurement and control system. Each routing board includes an analysis module and a plurality of thread modules with thread numbers. The synchronous triggering method is applied to any one of the routing boards and is used to trigger the target function board to synchronously process quantum computing tasks. In the attached Figure 1 method, the following steps are included.

[0049] Step S101: The analysis module analyzes the trigger instruction sent by the central control board and determines that a plurality of thread modules with the trigger state being the first trigger state in the trigger instruction are the first target thread modules; wherein, the trigger instruction includes the trigger states of all thread modules, and the first trigger state indicates that the corresponding thread module needs to be triggered.

[0050] Step S102: The analysis module generates a first trigger signal and outputs it to each first target thread module at the same pulse moment of the periodic pulse signal.

[0051] Step S103: Each first target thread module responds to the first trigger signal according to its working state and outputs a second trigger signal to the target function board; wherein, the target function board is the function board that receives the task packet of the quantum computing task to be executed sent by the routing board.

[0052] For easy understanding, in combination with Figure 2 the above quantum computing measurement and control system is described. Figure 2 is a schematic structural diagram of a quantum computing measurement and control system provided by an embodiment of the present application. In the Figure 2 shown quantum computing measurement and control system, it may include: a central control board, a plurality of routing boards, and a plurality of function boards.

[0053] In the Figure 2 shown central control board, it may include a thread execution module and a central control thread module. Among them, the number of central control thread modules may be multiple. For example, in the quantum computing measurement and control system corresponding to a 72-bit quantum chip, the number of central control thread modules is 5.

[0054] The above quantum computing measurement and control system may include multiple routing boards, such as the Figure 2 shown routing board, and three routing boards are integrated on the same hardware device. In actual design, Figure 2 the three shown routing boards may be respectively deployed on different hardware devices. In the Figure 2Each of the shown routing boards may include: a parsing module and multiple thread modules. For example, in a quantum computing measurement and control system corresponding to a 72-bit quantum chip, each routing board may include 5 thread modules. That is, the number of thread modules in each routing board matches the number of central control thread modules in the central control board. Note Figure 2 Only the composition of the functional modules in one routing board is exemplified herein, and the composition of the functional modules in other routing boards is the same. In addition, the above-mentioned quantum computing measurement and control system further includes multiple functional boards, and each functional board can be respectively deployed on different hardware devices.

[0055] The central control board is respectively communicatively connected to each routing board, that is, the central control board passes through Figure 2 the shown thread execution modules are respectively communicatively connected to each routing board. Among them, the central control board, the central control device integrated on the routing board, and the routing device usually adopt processors such as FPGA (Field Programmable Gate Array) and MCU (Microcontroller Unit). Each functional module is integrated inside the processor and is used for data communication, data processing, etc. Each routing board is communicatively connected to several functional boards.

[0056] Both the central control thread module in the central control board, the routing board, the thread module in the routing board, and the functional board have number information. For each quantum computing task to be executed, the required hardware resources are determined. Therefore, each task packet of the quantum computing tasks sent by the host computer contains the number information of the central control board, the routing board, the thread module, and the functional board for executing the quantum computing task. According to the number information in the task packet, the target routing board, the target thread module, and the target functional board can be determined.

[0057] In Figure 2 the shown quantum computing measurement and control system, the routing board is communicatively connected to the host computer (not shown in Note Figure 2 ), and receives the task packet sent by the host computer. Among them, the task packet can be a first task packet including various pulse waveform data, which is used for each functional board to generate corresponding pulse signals according to the pulse waveform data, such as pulse amplitude, pulse width, waveform pattern, etc.; the task packet can also be a second task packet including the number information of the central control board, the routing board, the thread module, and the functional board, the repetition times of the pulse signal, etc., which is related to each quantum computing task and is used for each board to cooperate to trigger the functional board to output specific pulse signals; for example, the target thread number, which corresponds to the thread number in the routing board, the target board number, which corresponds to the number of the functional board; the trigger information, which corresponds to the number of times, intervals, etc. of triggering the functional board to output pulse signals.

[0058] In Figure 2In the quantum computing measurement and control system shown, the routing board card receives the task packet sent by the host computer, and sends the first task packet to the corresponding target function board card according to the target thread number and target board card number in the second task packet. The target function board card is configured according to the pulse waveform data in the first task packet, and after the configuration is completed, it outputs the ready information. Then, the thread module in the routing board card obtains the ready information of each target function board card and forwards it to the central control board card. Furthermore, the central control board card outputs a trigger instruction according to the ready information to trigger the trigger of the thread module in the routing board card, and then the thread module in the routing board card triggers the target function board card to output a pulse signal corresponding to the pulse waveform data.

[0059] Among them, the trigger instruction sent by the central control board card includes the trigger status of all thread modules, and can trigger multiple routing board cards connected by communication and multiple thread modules in the routing board card to process multiple quantum computing tasks in parallel. The routing board card can obtain the trigger status of each thread module included in the trigger according to the received trigger instruction and generate a first trigger signal, and send it to the corresponding thread module. The thread module generates a second trigger signal according to the working state (that is, the idle state and execution state in the following text) in response to the first trigger signal and sends it to the target function board card, so as to trigger the target function board card connected by communication to process multiple quantum computing tasks in parallel.

[0060] In addition, when the routing board card parses the trigger instruction sent by the central control board card and generates a trigger signal, it is used to trigger the target function board card that is in the ready state after receiving the task packet and completing the configuration. The trigger instruction, target thread number, target function board card, etc. all have a corresponding quantum computing task to be executed.

[0061] In this process, the central control thread module in the central control board card enables the routing board card to start the parallel processing of multiple quantum computing tasks through the generated trigger instruction, that is, to prompt the routing board card to generate a trigger signal for triggering the parallel processing of multiple quantum computing tasks. The routing board card is used to start / trigger the parallel processing of multiple quantum computing tasks in the target function board card. Here, the parallel processing process of the quantum computing measurement and control system for quantum computing tasks will not be specifically described.

[0062] In the embodiment of the present application, for each routing board card, the thread module included in the routing board card corresponds one-to-one with the central control thread module in the above central control board card; that is, there is a central control thread module in each routing board card whose identification information is the same as the corresponding identification information of any thread module; in addition, for the function board card connected by communication to each routing board card, its identification information also corresponds to the thread module; in this embodiment, the identification information is the thread number.

[0063] In the above quantum computing measurement and control system, by deploying multiple central control thread modules on the above central control board and multiple thread modules on each routing board, the central control board and the routing board can simultaneously trigger the parallel processing of multiple quantum computing tasks, realizing multi-threaded quantum computing and improving the quantum computing efficiency.

[0064] The embodiments of the present application will be described below through specific examples.

[0065] For the above step S101, the parsing module parses the trigger instruction sent by the central control board, and determines that several thread modules with the trigger state being the first trigger state in the trigger instruction are the first target thread modules; wherein, the trigger instruction includes the trigger states of all thread modules, and the first trigger state indicates that the corresponding thread module needs to be triggered.

[0066] When the central control sends out the trigger instruction, it is sent to each routing board in a broadcast form, and each routing board receives the same trigger instruction and parses the trigger instruction. Specifically, the trigger instruction contains the trigger states of all thread modules of this routing board. The trigger state usually includes the first trigger state indicating that the corresponding thread module needs to be triggered and the second trigger state indicating that it does not need to be triggered. For the first trigger state that needs to be triggered, it means that the corresponding thread module needs to perform trigger output, and the parsing module determines the corresponding thread module as the first target thread module.

[0067] Among them, the trigger states included in each trigger instruction are different, and the number of the corresponding first target thread modules is also different, which needs to be determined according to the quantum computing tasks to be executed in specific applications.

[0068] As shown in the schematic diagram of the trigger instruction Figure 3 shown, the trigger instruction has a preset address bit number, a base type, and the mask information on each preset address bit number represents the trigger state of the corresponding thread number. The correspondence between the preset address bit number and the thread number exemplified in the appendix Figure 3 is only an example, and the trigger state using a high-level flag and a low-level flag is also only an example.

[0069] For the above step S102, the parsing module generates a first trigger signal and outputs it to each first target thread module at the same pulse moment of the periodic pulse signal. After determining the first target thread modules corresponding to a trigger instruction through step S101, it is necessary to trigger the first target thread modules, and the parsing module generates a first trigger signal. The number of the first trigger signals can be one, which is sent to the first target thread modules respectively; it can also be several, and the number corresponds to the first target thread modules and is sent respectively.

[0070] When the parsing module sends the first trigger signal to each first target thread module, it outputs according to the periodic pulse signal at the same pulse moment of the signal, ensuring that the first trigger signals output to each first target thread module are synchronized. The periodic pulse signal is a pulse waveform with the same pulse interval, usually output by a clock source module or a clock chip and sent to the parsing module in the routing board.

[0071] Regarding step S103, each first target thread module responds to the first trigger signal according to its working state and outputs a second trigger signal to the target function board. Among them, the target function board is the function board that receives the task packet of the quantum computing task to be executed sent by the routing board.

[0072] As described above, for each quantum computing task to be executed, a corresponding function board outputs a pulse signal to the quantum processor. The corresponding relationship is included in the task packet, sent by the host computer to the routing board, and the routing board obtains the corresponding relationship (target board number) in the task packet, and sends the pulse signal data to the target function board with the target board number. The target function board configures the pulse signal data, outputs a ready message to the routing board after the configuration is completed, and is in a state of waiting for trigger output, waiting for the routing board to send the second trigger signal.

[0073] After determining the first target thread module through the above steps S101 - S102, the first target thread module responds to the first trigger signal according to its working state and outputs a second trigger signal. Among them, the working state includes a loading state and an idle state. Specifically, the loading state means that the thread module receives a data packet and configures according to the task parameters in the data packet, and outputs a ready message after the configuration is completed, which is used to indicate that the thread module is in a state of waiting for trigger after the task parameter configuration is ready. The idle state means that the thread module does not receive a data packet and does not configure task parameters, and does not participate in the quantum computing task.

[0074] The first target thread module responds to the first trigger signal according to its working state, ensuring the accuracy of the trigger of the target function board, and thus ensuring the accurate execution of the quantum computing task. In addition, the first trigger signals received by each first target thread module are synchronized, and the first target thread modules respond to the first trigger signal according to their working states are also synchronized, so that the second trigger signals output to the target function board are also synchronized; ensuring that the target function board processes the quantum computing task according to the synchronized second trigger signal, thereby improving the synchronization of the quantum computing measurement and control system in executing the quantum computing task.

[0075] As shown in the appendix Figure 4 shown, the parsing module parses the trigger instruction sent by the central control board, and determines that several thread modules with the trigger state being the first trigger state in the trigger instruction are the first target thread modules, including the following steps.

[0076] Step S1011: The parsing module receives and parses the trigger instruction sent by the central control board to obtain the trigger status corresponding to the thread numbers of all thread modules; wherein, the trigger status includes a first trigger status that each thread module needs to trigger and a second trigger status that does not need to be triggered.

[0077] Step S1012: The parsing module determines that the thread module corresponding to the thread number and the first target thread number is the first target thread module; wherein, the first target thread number is the thread number corresponding to the first trigger status.

[0078] The parsing module parses the trigger instruction to obtain the trigger status corresponding to the thread numbers of all thread modules. For the first trigger status that needs to be triggered, it means that the corresponding thread module needs to perform trigger output. The parsing module determines the corresponding thread number as the first target thread number and determines the module with the thread number as the first target thread number as the first target thread module.

[0079] As shown in the appendix Figure 5 As shown, in this embodiment, the parsing module generates a first trigger signal and outputs it to each first target thread module at the same pulse moment of the periodic pulse signal, including the following steps.

[0080] Step S2011: The parsing module generates a first trigger signal.

[0081] Step S2012: The parsing module outputs the first trigger signal to each first target thread module at the next pulse rising edge of the current moment when obtaining the periodic pulse signal.

[0082] After the parsing module generates the first trigger signal, it waits to receive the periodic pulse signal. After receiving the periodic pulse signal, each pulse rising edge or falling edge can be used to output the first trigger signal. In this embodiment, the parsing module outputs the first trigger signal to each first target thread module at the next pulse rising edge of the current moment when receiving the periodic pulse signal, reducing the waiting time of the parsing module and outputting the synchronized first trigger signal to each first target thread module as soon as possible, improving the trigger efficiency of the first target thread module, and thus improving the efficiency of performing the quantum computing task.

[0083] As shown in the appendix Figure 6 As shown, in this embodiment, the second trigger signal is used to trigger the thread module that has loaded the task package and completed the configuration. Therefore, the thread module needs to be configured according to the received task package before receiving the second trigger signal. Before the first target thread module responds to the first trigger signal according to the working state and outputs the second trigger signal to each functional board, the method further includes the following steps.

[0084] Step S111: The parsing module receives and parses the task packet sent by the host computer, and obtains the second target thread number, the target board number, and the trigger information.

[0085] In this step, the task packet sent by the host computer is the task packet of the quantum computing task to be executed, which includes the second target thread number, the target board number, and the trigger information. Among them, the second target thread number is the number of the thread module that executes this task packet; the target board number is the number of the function board that executes this task packet; the trigger information is the information of the second trigger signal output by the routing board.

[0086] The corresponding information of these function boards has been determined when the host computer issues them, and the task packet is forwarded according to the corresponding information when the routing board forwards the task packet. Among them, when the host computer receives the quantum computing task, it will schedule according to the working status and idle status of each device and module in the quantum computing measurement and control system, and determine the second target thread number and the target board number corresponding to each task packet; the trigger information is determined according to the number of repetitions of the computing task.

[0087] Each routing board is communicatively connected to several function boards with board numbers. After the host computer determines the target board number, the number of the routing board communicatively connected to it is also correspondingly determined. Therefore, according to the target board number of the target function board in the task packet sent by the host computer and the second target thread number in the routing board, the target routing board, the target second thread module, and the target function board that execute this task packet can be determined.

[0088] In addition, not only the routing board needs to be configured, but the function board also needs to be configured. When the routing board receives the first task packet containing pulse waveform data, it forwards it to the target function board corresponding to the target board number. The target function board configures the pulse waveform data, and outputs the ready information to the communicatively connected routing board after the configuration is completed.

[0089] Step S112: The parsing module sends the target board number and the trigger information to the second target thread module whose thread number corresponds to the second target thread number.

[0090] The parsing module distributes according to the second target thread number included in the task packet, and distributes the target board number and the trigger information to the second target thread module whose thread number corresponds to the second target thread number.

[0091] Step S113: The second target thread module receives the target board number and the trigger information.

[0092] Step S114: The second target thread module updates its working status from the idle status to the loading status.

[0093] After receiving the target board card number and trigger information, the second target thread module enters the loading state and waits in this state for the arrival of the first trigger signal used to trigger the output of this thread module; when the second target thread module receives the first trigger signal sent by the parsing module, it responds to the first trigger signal and outputs a second trigger signal.

[0094] In this embodiment, the first target thread module responds to the first trigger signal according to the working state and outputs the second trigger signal to each functional board card, including: the third target thread module responds to the first trigger signal and outputs the second trigger signal to the functional board card corresponding to the target board card number according to the trigger information; wherein, the third target thread module is the second target thread module in the loading state in the first target thread module.

[0095] Specifically, the central control board card sends the trigger instruction in a broadcast manner to all routing board cards. Therefore, each routing board card will determine the first target thread module in this routing board card after parsing the trigger instruction; not all first target thread modules in the routing board cards need to execute the trigger, and it needs to be matched according to the working state of the first target thread module.

[0096] Each second target thread module is determined according to the second target thread number in the task packet when the routing board card receives the task packet to be executed for quantum computing, and is a thread module that has loaded the target board card number and trigger information in the task packet and is in the loading state and needs to execute the trigger output; therefore, the second target thread module is included in the first target thread module, and all second target thread modules in the first target thread module that are in the loading state need to trigger the output. These thread modules are determined as the third target thread module, and the second trigger signal is output to the functional board card corresponding to the target board card number according to the trigger information.

[0097] Whether it is the first target thread module, the second target thread module, or the third target thread module, they are all one or several thread modules in the routing board card, and are numbered and named according to their execution states; the first target thread module is determined according to the trigger state after the routing board card parses the trigger instruction sent by the central control board card; the second target thread module is determined according to the second target thread number in the task packet when the routing board card receives the task packet to be executed for quantum computing; and the third target thread module is the second target thread module in the loading state in the first target thread module.

[0098] In this embodiment, the trigger information includes the number of triggers and the trigger interval duration. The trigger interval duration is an integer multiple of the pulse interval duration of the periodic pulse signal. The third target thread module outputs a second trigger signal to the function board corresponding to the target board number according to the trigger information, including: the third target thread module outputs a second trigger signal to the function board corresponding to the target board number according to the number of triggers and the trigger interval duration.

[0099] Quantum computing requires multiple repeated measurements and statistics on the results of multiple repeated measurements. During multiple repeated measurements, each measurement is triggered by a second trigger signal, and multiple triggers are repeated. Moreover, each trigger needs to ensure synchronization at the same pulse moment of the periodic pulse signal. Multiple repeated triggers need to ensure that they are all at the pulse moment of the periodic pulse signal.

[0100] Exemplarily, when the first second trigger signal is output at the rising edge moment of the periodic pulse signal, each subsequent second trigger signal is output at the rising edge moment of the periodic pulse signal, rather than at the falling edge moment or other moments, ensuring that multiple second trigger signals are synchronized with respect to the pulse rising edge or falling edge moment of the periodic pulse signal.

[0101] The periodic pulse signal has a pulse interval duration. The trigger information in the task packet includes the number of triggers and the trigger interval duration, and the trigger interval duration is an integer multiple of the pulse interval duration, thereby ensuring that multiple second trigger signals are synchronized with respect to the pulse rising edge or falling edge moment of the periodic pulse signal.

[0102] Therefore, when the third target thread module outputs a second trigger signal to the function board corresponding to the target board number according to the number of triggers and the trigger interval duration, the synchronization of multiple repeated outputs of the second trigger signal ensures the consistency of repeated measurements.

[0103] As shown in the appendix Figure 7 In this embodiment, as shown, the thread module includes a trigger generation counter and a trigger number counter. The third target thread module outputs a second trigger signal to the function board corresponding to the target board number according to the number of triggers and the trigger interval duration, including the following steps.

[0104] Step S3011: The trigger generation counter generates a second trigger signal and outputs it to the function board corresponding to the target board number when counting to each trigger interval duration.

[0105] Step S3012: The trigger number counter increments the current trigger number by 1 when each second trigger signal is generated.

[0106] Step S3013: The trigger number counter stops outputting the second trigger signal when the current trigger number is equal to the number of triggers.

[0107] The trigger generation counter and the trigger times counter output multiple periodic second trigger signals according to the trigger times and the trigger interval duration, ensuring the synchronization of the pulse moments of the multiple second trigger signals relative to the pulse moment of the periodic pulse signal.

[0108] As described above, for the thread module, its working states include the idle state, the loading state, and the execution state. Among them, the idle state is when the thread module has no task package loaded. In this state, the parsing module can allocate the task package sent by the host computer to this thread module according to the target second thread module; the loading state is when the thread module loads the target board number and trigger information in the task package. In this state, the thread module can only respond to the first trigger signal sent by the parsing module and will not load other task packages allocated by the parsing module; the execution state refers to the state where the thread module receives the first trigger signal and responds to output the second trigger signal. In this state, it will not load other task packages allocated by the parsing module, nor will it respond to other first trigger signals sent by the parsing module, and it will continue until the number of times of the second trigger signal reaches the trigger times in the trigger information, stop outputting the second trigger signal and update the working state to the idle state.
