Detailed Description
The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the application.
As shown in fig. 1, an embodiment of the present application provides a quantum control system 1, which includes a control module 11, a routing module 12 and a plurality of signal processing module groups 13 that are sequentially connected in a communication manner, where the routing module 12 is configured to receive a reset instruction sent by the control module 11 and forward the reset instruction to each of the signal processing module groups 13; the control module 11 is configured to send a first reset instruction for resetting the task parameters of the control module 11, the routing module 12 and the signal processing module group 13 in the communication link for performing the task; or a second reset instruction for resetting the firmware parameters and the task parameters of the target signal processing module group 13 is sent; or a third reset instruction for resetting the synchronization parameters, firmware parameters and task parameters of the control module 11, the routing module 12 and all the signal processing module groups 13.
The signal processing module group 13 is integrated with a plurality of functional modules, such as a signal output module, a signal acquisition module, a signal processing module, and various functional modules for driving and measuring the quantum processor. The specific number of the signal processing module groups 13 needs to be set correspondingly according to the number of the qubits on the quantum processor so as to meet the requirements of all the qubits. The various instructions and parameters issued by the control module 11 are forwarded to the respective signal processing module groups 13 through the routing module 12.
The quantum control system 1 has a plurality of signal channels, wherein the signal processing module group 13 drives and measures the quantum processor through the signal channels. The signal output by each channel contains task parameters, firmware parameters and synchronization parameters, wherein the task parameters are related to tasks executed by each module, the firmware parameters are related to initial parameter configuration and operation states of each module, the synchronization parameters of the signal channels are related to delay of a signal transmission link, the delay is influenced by logic delay of each module in the quantum control system 1, delay of a chip and delay of a line between the modules, and delay of a transmission line from the signal channels to a quantum processor, therefore, the synchronization parameters are influenced by a plurality of factors, when the synchronization parameters of the signal channels of the equivalent sub control system 1 are not synchronous, accuracy of driving and testing of the quantum processor is directly reduced, the synchronization parameters of each signal channel need to be reset and calibrated, and a calibration flow of the synchronization parameters is very complex, and time and labor are wasted when the calibration flow is operated.
It should be added that the signal channel includes both a signal output channel and a signal input channel, when the quantum processor is controlled, a driving signal is output to the quantum processor through the signal output channel, and when the control result of the qubit is tested, an output signal carrying the control result and output by the quantum processor is collected through the signal input channel.
When the task being executed by the quantum control system 1 needs to be terminated, a first reset instruction for resetting the task parameters of the control module 11, the routing module 12 and the signal processing module group 13 in the communication link for executing the task can be sent through the control module 11, so that the reset of the task parameters of all the functional modules participating in the task is realized. When the firmware parameters or the task parameters of the one or more signal processing module groups 13 are abnormal and cannot work normally, a second reset instruction for resetting the firmware parameters and the task parameters of the target signal processing module group 13 can be sent through the control module 11. When the synchronization parameters of the signal channels of the quantum control system are not fixed, and the delays of a plurality of signal channels are not synchronous, a third reset instruction for resetting the synchronization parameters, the firmware parameters and the task parameters of the control module 11, the routing module 12 and all the signal processing module groups 13 can be sent by the control module 11, so that all the parameters of the quantum control system are reset.
Therefore, the application sends the corresponding reset instruction according to the type of the module to be reset and the type of the parameter to be reset in each module, thereby realizing the flexible selection of the reset instruction according to the reset object, further realizing the reset effect with high efficiency and improving the operation efficiency of the quantum control system 1.
As an implementation manner of the embodiment of the present application, the control module 11 is further configured to receive a reset response sent by the routing module 12 and send the reset response to the server, where the reset response is an instruction that the signal processing module group 13 responds to the reset instruction to execute the reset operation and output the reset operation. When the signal processing module group 13 responds to the reset instruction to execute the reset operation, the reset return instruction is output to the routing module 12, and is forwarded to the control module 11 through the routing module 12, so that the current reset operation is represented to be executed. The control module 11 receives parameters of other work tasks issued by the server, and sends one or more of corresponding synchronization parameters, firmware parameters and task parameters to the signal processing module group 13 to execute the work.
As an implementation manner of the embodiment of the present application, the control module 11 is further configured to receive a calibration instruction sent by the server based on the reset feedback, where the calibration instruction is used to calibrate the synchronization parameters of the control module 11, the routing module 12, and all the signal processing module groups 13. After the synchronization parameters of all the functional modules of the quantum control system 1 are reset through the third reset instruction, recalibration is needed, and synchronization of the synchronization parameters among all the signal channels of the quantum control system 1 is ensured.
As an implementation of the embodiment of the present application, the control module 11, the routing module 12 and the signal processing module group 13 are further configured to reset one or more of the synchronization parameter, the firmware parameter and the task parameter in response to a key command. In addition to resetting all parameters of the control module 11, the routing module 12 and the signal processing module group 13 by using a reset instruction, an operation mode of resetting by using a key instruction may be used. It can be understood that the instruction reset is performed by running a program, and the key instruction reset is performed by a key manner, so that the user needs to manually participate in the reset operation.
It is conceivable that when the control module 11, the routing module 12 and the signal processing module group 13 cannot operate normally, the reset operation cannot be performed after receiving the reset instruction, and at this time, the expected reset effect cannot be achieved by the program reset mode, and human participation is required, and the reset operation is performed by adopting the key instruction mode. By combining instruction reset and key reset, the reset operation of the quantum control system 1 is ensured to be executed more smoothly.
As one implementation of the embodiment of the present application, the control module 11, the routing module 12, and the signal processing module group 13 are all provided with a key reset unit configured to initiate a reset operation in response to the key command.
