Detailed Description
The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
As shown in fig. 1, an embodiment of the present application provides a quantum measurement and control system 10, which includes a control module 101, a plurality of first signal modules 103, and a first routing module 102 configured to perform signal transmission between the first signal modules 103 and the control module 101. Wherein the first signal module 103 is configured to: generating a control signal to be triggered and output to a quantum chip and a ready signal output to the control module 101, wherein the control signal corresponds to a quantum computing task to be executed; and receiving a trigger signal fed back by the control module 101 based on the ready signal, and synchronously triggering the control signal to be output to the quantum chip based on the trigger signal.
In the field of quantum measurement and control, a plurality of quantum bit units are integrated on a quantum chip, wherein each quantum bit unit is a two-level system and has parameters such as transition frequency, transition energy and the like, the parameters need to be regulated and controlled by applying corresponding regulating and controlling signals, specifically, the quantum measurement and control system 10 outputs the regulating and controlling signals to the quantum bit to control the quantum state of the quantum bit, and quantum computation of quantum computation tasks is realized. Moreover, for the quantum computing task to be executed, with the improvement of the kind and complexity of the task, the number of the qubit units that need to participate is also increasing, that is, the output channels of the quantum measurement and control system 10 are also increasing.
After a large number of tests and experiments, the applicant provides a quantum measurement and control system 10 capable of improving synchronous output of control signals among a plurality of channels. Specifically, a plurality of first signal modules 103 are arranged in the quantum measurement and control system 10, and the first signal modules 103 are used for generating control signals to be output to a quantum chip, wherein the types and parameters of the control signals depend on a quantum computing task to be executed. After the first signal module 103 generates the control signal, the control signal is not immediately output to the quantum chip, but a ready signal is continuously generated and sent to the control module 101, where the ready signal represents that the first signal module 103 has generated the control signal to be output, and waits for an output instruction.
It should be added that, for the quantum computing task to be executed, a plurality of control signals are required, that is, a plurality of first signal modules 103 are required to act together, so that after each first signal module 103 participating in the quantum computing task to be executed generates a corresponding control signal, it is required to continue to generate a ready signal, and send the ready signal to the control module 101 through the first routing module 102. After receiving the ready signal sent by each first signal module 103 forwarded by the first routing module 102, the control module 101 outputs a trigger signal, and forwards the trigger signal to the corresponding first signal module 103 through the first routing module 102. The trigger signals and the ready signals are in one-to-one correspondence, and the trigger signals output by the control module 101 can control the plurality of first signal modules 103 to simultaneously output control signals to the quantum chip, so as to ensure output synchronization of the control signals, that is, ensure synchronization of signals output by each channel in the quantum measurement and control system 10.
As shown in fig. 2, as another implementation manner of the embodiment of the present application, the number of the first routing modules 102 in the quantum monitoring and control system 10 may also be multiple. When the number of the first signal modules 103 is large, a plurality of first routing modules 102 may be adopted, and a certain number of first signal modules 103 are adapted through a single first routing module 102, so that the signal forwarding efficiency between the control module 101 and the plurality of first signal modules 103 can be improved.
The method comprises the steps of arranging a control module 101, a plurality of first signal modules 103 and a first routing module 102 for forwarding signals between the first signal modules 103 and the control module 101. Wherein the first signal module 103 is configured to: generating a control signal to be triggered and output to a quantum chip and a ready signal output to the control module 101, wherein the control signal corresponds to a quantum computing task to be executed; and receiving a trigger signal fed back by the control module 101 based on the ready signal, and synchronously triggering the control signal to be output to the quantum chip based on the trigger signal. The control module 101 receives the ready signals output by the first signal modules 103, that is, it is determined that the control signals of the first signal modules 103 are generated completely, at this time, the trigger signals are uniformly sent to the first signal modules 103, and the trigger signals sent by the control module 101 trigger the output of the control signals, so that the control signals of the first signal modules 103 are synchronously output, and the signal synchronization consistency of the quantum measurement and control system 10 is improved.
As shown in fig. 3, as an implementation manner of the embodiment of the present application, the quantum measurement and control system 10 provided by the present application further includes a second signal module 104; wherein the second signal module 104 is configured to: generating a measurement signal for reading bit information of the quantum chip, wherein the bit information corresponds to the control signal; and acquiring and processing a return signal output by the quantum chip to obtain a calculation result, and forwarding the calculation result to the control module 101 through the first routing module 102, wherein the return signal corresponds to the measurement signal.
The first signal module 103 is configured to generate a control signal corresponding to a quantum computing task to be executed and synchronously trigger the control signal to be output to the quantum chip through the trigger signal, and the quantum chip completes the corresponding quantum computing task based on the control signal. Bit information of the quantum chip after the quantum computing task is completed needs to be obtained by reading the measurement signal, and the bit information is processed to obtain a result of the corresponding quantum computing task.
Specifically, a measurement signal for reading bit information of the quantum chip is generated by the second signal module 104. After the measurement signal is output to the quantum chip, a return signal fed back by the quantum chip is collected, the return signal carries bit information of the quantum chip at the moment, and the return signal is processed through a signal module to obtain a specific calculation result corresponding to the quantum calculation task to be executed.
It should be noted that the number of the second signal modules 104 may be one or more, for example, when the number of qubits for running a quantum computing task on a quantum chip is small, and only a small number of measurement signals are needed, one second signal module 104 may meet the requirement. However, when the number of qubits on the quantum chip is large, the number of qubits for simultaneously operating the quantum computing task is large, or a plurality of quantum computing tasks are simultaneously operated, a plurality of measurement signals need to be output to the quantum chip for measurement through the second signal module 104, and at this time, the number of one second signal module 104 is obviously not enough to meet the test requirement, and a plurality of second signal modules 104 need to be arranged. The test object of the quantum measurement and control system 10 designed by the applicant is a quantum chip with more than one hundred digits, so in the specific implementation of the present application, a plurality of second signal modules 104 are arranged on the quantum measurement and control system 10.
In addition, the bit information of the quantum chip corresponds to the control signal, the corresponding control signal is applied to the quantum chip based on the quantum computing task to be executed, and the quantum chip carries out operation based on the control signal to obtain the corresponding bit information; the return signal corresponds to the measurement signal, the measurement signal is used for measuring bit information, and the return signal carrying the bit information is analyzed and processed to obtain a calculation result of the quantum calculation task to be executed. Control signals are output to the quantum chip through the first signal module 103, and bit information of the quantum chip is collected and processed through the second signal module 104, so that a calculation result is obtained, division of work of control and measurement of the quantum chip is realized, and integration and expansion of the first signal module 103 and the second signal module 104 are facilitated.
On the other hand, the control module 101 in this embodiment is further configured to receive and process the calculation result, and output a feedback signal based on the processing result, where the feedback signal is used to adjust the first signal module 103 to generate a control signal corresponding to a next quantum computing task to be executed. When the applicant realizes the control and measurement of the quantum chip through the quantum measurement and control system 10, the feedback control based on the calculation result is provided.
Specifically, after the second signal module 104 processes the return signal of the quantum chip operation to obtain the computation result corresponding to the quantum computation task, the computation result is sent to the control module 101 through the first routing module 102, the control module 101 determines whether the quantum computation task is executed completely based on the received computation result, if so, the control module 101 outputs a feedback signal, forwards the feedback signal to the corresponding first signal module 103 through the first routing module 102, controls the first signal module 103 to enter the processing flow of the next to-be-executed quantum computation task, that is, the first signal module 103 generates the control signal and the ready signal corresponding to the next to-be-executed quantum computation task, and repeats the above flow. Through the feedback control of the quantum measurement and control system 10, the first signal module 103 can work efficiently, and the calculation efficiency can be improved when more and more complex quantum calculation tasks are operated.
As shown in fig. 4, as an implementation manner of the embodiment of the present application, in the embodiment of the present application, the first signal module 103 includes a first DAC unit 1031, and the second signal module 104 includes a second DAC unit 1041 and an ADC unit 1042; wherein the first DAC unit 1031 is configured to generate the control signal; the second DAC unit 1041 is configured to generate the measurement signal; the ADC unit 1042 is configured to acquire and process the feedback signal to obtain the calculation result, and forward the calculation result to the control module 101 through the first routing module 102.
In the field of electronic technology, as a source device for generating a signal, one or more of a signal generator, a waveform generator, a signal source, a digital-to-analog converter, an analog-to-digital converter, and the like can be selected. In the specific implementation of the present application, the digital-to-analog conversion and the analog-to-digital conversion, i.e., the ADC and the DAC, are selected. Specifically, the first signal module 103 is used for generating a control signal for controlling the quantum chip, where the control signal is an analog signal having a specific waveform, and therefore a DAC unit, i.e., the first DAC unit 1031, is used. The second signal module 104 needs to generate a measurement signal for sampling bit information of the quantum chip, that is, needs a signal generating function of the DAC unit, and needs to process and analyze the bit information, that is, needs a function of the ADC unit, so that the second signal module 104 employs the second DAC unit 1041 and the ADC unit 1042.
The first DAC unit 1031 and the second DAC unit 1041 have similar functions, and are both used for generating analog signals, but the functions of the generated analog signals are different, the former is used for controlling the quantum chip to operate the quantum computation task, and the latter measures the operation result of the quantum chip. In the quantum measurement and control system 10 in the embodiment of the application, the DAC unit and the ADC unit are integrated on the board card, so that the integration and the expansion of the quantum measurement and control system 10 are easily realized.
As shown in fig. 5, as an implementation manner of the embodiment of the present application, the quantum measurement and control system 10 of the embodiment of the present application further includes a server 106 and a second routing module 105; the server 106 is configured to output task information corresponding to the to-be-executed quantum computing task, where the task information includes a task parameter and first information, and the first information is used to determine the first signal module 103 that receives the task parameter; the second routing module 105 is configured to send the task parameter to the corresponding first signal module 103 through the first routing module 102 according to the first information.
The quantum computing task to be executed is usually from a user terminal, for example, a user terminal of a classical computer or a user terminal of a quantum computer, and the embodiment of the present application is configured to receive the quantum computing task to be executed by setting the server 106. Specifically, the task information corresponding to the quantum computing task to be executed is received and output to other modules of the quantum measurement and control system 10. The task information includes task parameters and first information, and the task parameters are used for the first signal module 103 to generate control signals, such as parameters of cycle times, cycle periods, waveforms, and the like of the control signals; and the first information is information for determining the first signal module 103 that generated the control signal, such as the module code 1, 2, 3 … n of the particular first signal module 103. In addition, when the number of the first routing modules 102 is plural, the first routing module 102 also has module codes 1, 2, 3 … n.
Specifically, since several first signal modules 103 correspond to one first routing module 102, based on the codes of the first signal modules 103 in the first information, the forwarding paths of the task parameters sent by the second routing module 105 to the first signal modules 103 can be determined. For example, the first routing module 103 encoded as 1 is adapted to the first signal modules 103 encoded as 1-5, and the first routing module 102 encoded as 2 is adapted to the first signal modules 103 encoded as 6-10. When the task parameter needs to be sent to the first signal modules 103 with codes of 3 and 4, the forwarding path corresponding to the first information, i.e., the second routing module 105, is from the first routing module 102 with code of 1 to the first signal modules 103 with codes of 3 and 4; when the task parameter needs to be sent to the first signal modules 103 with codes of 6 and 7, the forwarding path corresponding to the first information is from the second routing module 105 to the first routing module 102 with code of 2 to the first signal modules 103 with codes of 6 and 7. It should be noted that, the forwarding path from the second routing module 105 to the first signal module 103 through the first routing module 102 for the task parameter corresponding to the first information is described herein, which is only an example, and when the quantum measurement and control system 10 of the present application is applied to a multi-bit quantum chip for testing, it needs to be specifically distinguished according to a specific quantum computing task.
It can be found that when the number of the first signal modules 103 in the quantum measurement and control system 10 is large, the execution carrier of the task parameter, that is, the first signal module 103, can be efficiently allocated through the forwarding functions of the second routing module 105 and the first routing module 102, so that the plurality of first signal modules 103 cooperatively work, and further the execution efficiency of the quantum computing task is improved.
In addition, as an implementation manner of the embodiment of the present application, the second routing module 105 is further configured to transmit the first information to the control module 101; the control module 101 is further configured to generate the trigger signal based on the ready signal and the first information that are output after the first signal module 103 generates the control signal according to the task parameter.
After the first signal module 103 generates the corresponding control signal and the ready signal according to the task parameter, the ready signal is sent to the control module 101, and the control module 101 sends a trigger signal to the first signal module 103 based on the ready signal to trigger the first module to synchronously output the control signal to the quantum chip. In the implementation process, the applicant finds that the server 106 forwards the first information to the control module 101 through the second routing module 105, and after receiving the ready signal sent by the first signal module 103, the control module 101 determines that all the first signal modules 103 corresponding to the module codes included in the first information send the ready signals to the control module 101 based on comparison between codes of the first signal modules 103 corresponding to the ready signal and codes of the first signal modules 103 in the first information, and after generating the trigger signal and forwarding the trigger signal to the first signal modules 103 through the first routing module 102, it can be ensured that all the control signals corresponding to the quantum computing tasks to be executed are generated, and the trigger signal is synchronously triggered and output to the quantum chips, so that missing of the control signals required for executing the quantum computing tasks is avoided, and accuracy of the computing results is ensured.
As shown in fig. 5, as an implementation manner of the embodiment of the present application, the first routing module 102, the second routing module 105, and the control module 101 communicate with each other through an ethernet. Through ethernet communication, the forwarding rate of data or signals between the first routing module 102, the second routing module 105, and the control module 101 can be increased.
As an implementation of this embodiment of the application, the control signal has a timing, and the timing is used for synchronizing the output of the control signal. Specifically, the first signal module 103, the first routing module 102, and the control module 101 use the same clock source, and after receiving the ready signal output by the first signal module 103, the control module 101 sends a synchronous trigger signal to be forwarded to each first signal module 103 through the first routing module 102, so as to ensure synchronization of triggering, that is, ensure that the timing sequence of output of the control signal is synchronous.
As shown in fig. 6, an embodiment of the present application provides a structure diagram of a quantum measurement and control system 10, specifically, the quantum measurement and control system includes a plurality of chassis 110, where each chassis 110 includes a first routing module 102 and a plurality of first signal modules 103, and the first routing module 102 is responsible for forwarding data or signals between a corresponding number of first signal modules 103 and a control module 101 and between the corresponding number of first signal modules 103 and a second routing module 105.
