[0002] The current quantum chip calibration software is generally developed for specific measurement and control hardware environments of specific configuration chips. Since the quantum chip configurations of various quantum computers are significantly different and the brands of quantum measurement and control equipment are also different, the adaptability of the calibration software is severely restricted. With the development of superconducting quantum computing technology, each quantum computer will have multiple users in the future, and each user can run multiple calibration tasks; each calibration task may calibrate multiple quantum bits of a quantum chip in parallel, and the calibration results of the same quantum chip by multiple users should not affect each other.

[0003] Secondly, after the user completes the calibration task, he needs to create a quantum algorithm task and execute it on the superconducting quantum computer. In response to the quantum algorithm task requirements of different users, the system must first realize the mapping between the logical quantum bits in the quantum circuit and the real quantum bits in the selected measurement and control environment, and map the calibration parameters to the quantum circuit parameters. Secondly, the system compiles the quantum circuit created by the user, realizes the construction of pulse instructions for each channel (drive, control, detection, reading) of each quantum bit, and encapsulates it into a quantum algorithm task. Similarly, different operators under different quantum computers can perform multiple algorithm tasks, and different algorithm tasks need to be executed independently of each other.

[0033] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0034] In order to enable each user to independently complete various calibration experiments on each quantum computer, update and maintain the characterization and calibration results corresponding to the calibration experiments, and use the characterization and calibration results as system parameters of the quantum cloud platform, an embodiment of the present invention provides a superconducting quantum computer configuration management system that supports multiple environments and multiple parameter spaces, such as Figure 1 As shown, including:

[0035] The hardware device configuration module corresponds to the measurement and control environment of the quantum computer so as to meet the adaptation requirements of various measurement and control environments.

[0036] The hardware equipment configuration module includes: hardware environment interface design, quantum chip interface design and multi-task multi-user parameter space design, such as Figure 2 shown.

[0037] The design of the hardware environment interface involves multi-environment interface design technology. The measurement and control system of the superconducting quantum computer consists of a low-temperature environment, a low-temperature measurement and control system, and a room-temperature measurement and control system. Among them, the room-temperature measurement and control systems used to measure and control different quantum computers are also different. Therefore, if you want to support the installation of multiple quantum computers, you first need to design a unified interface for their respective hardware environments. The design of the hardware environment interface must include the design of the room-temperature measurement and control device driver interface required by the quantum computer, the design of the connection configuration between the quantum chip and the room-temperature measurement and control device, and the design of the corresponding quantum chip parameter calibration experiment interface under different measurement and control environments. The interface is used to connect the calibration experiment and the environmental measurement and control equipment. The experimental parameters are sent to the measurement and control equipment by the interface, and the quantum calibration experiment is decoupled from the measurement and control hardware so that the calibration experiment can adapt to different hardware environments.

[0038] Hardware equipment refers to the measurement and control equipment of the measurement and control environment, including the parameters required to connect the equipment and the default configuration items of the equipment. For general users, it can be viewed but not modified.

[0039] According to readability, module views are divided according to functions, as follows: Figure 3 As shown, it specifically includes: JPA control module, quantum analysis module, quantum bit drive module and flux bias module. In each sub-module, the devices can be added, deleted or modified. Taking a 66-qubit superconducting quantum computer as an example, there are a total of 110 couplers and 11 read lines.

[0040] like Figure 4 As shown in FIG. 1 , the JPA control module has 11 read lines, and is therefore controlled by 11 JPAs. Each JPA consists of a microwave source channel and a DC source channel, which correspond to the corresponding types of hardware devices. Figure 5 As shown in the figure, the quantum analysis module consists of 11 reading and analysis channels, each of which consists of a microwave source channel, an arbitrary waveform generator channel and a quantum analyzer channel, which correspond to the corresponding types of hardware devices. Figure 6 As shown in the figure, in the qubit driving module, the quantum chip is divided into 11 groups of qubits, each group consists of 6 qubits. The driving signal of each qubit consists of a microwave source channel and an arbitrary waveform generator channel, which correspond to the corresponding types of hardware devices. Figure 7 As shown in the figure, the flux bias module divides the quantum chip into 11 quantum groups, each with 6 quantum bits and 11 couplers (the last quantum group does not contain a coupler). The flux bias of each quantum bit is controlled by an arbitrary waveform generator, and the flux bias of each coupler is also controlled by an arbitrary waveform generator, corresponding to the corresponding types of hardware devices.

[0041] In order to make the calibration experiment adaptable to each quantum computer and its measurement and control environment, it is necessary to design the experimental configuration for the specific environment. As part of the initialization of the calibration experiment task, the user can choose to modify or not modify the configuration items in the experimental configuration. The experimental configuration set is a calibration experiment configuration set established for a certain measurement and control environment. It has multiple different calibration experiment configurations. Each experimental configuration characterizes and calibrates the quantum chip of the corresponding environment through the quantum calibration software, and writes the results into the system configuration. Therefore, each experimental configuration in the experimental configuration set corresponds to a system configuration in the system configuration set, thereby supporting various quantum chip calibration experiments.

[0042] like Figure 8 The experimental configuration management shown is divided into quantum groups. The experimental configuration is used as a global variable for the user to control the quantum chip and its measurement and control environment. The configuration is loaded and the calibration experiment is executed. Each version of the experimental configuration should correspond to a complete set of calibration experiment processes and the results obtained from each experiment. Each basic calibration experiment also corresponds to the global state of all quantum group qubits and couplers under the experimental type. Its leaf node configuration items are as follows Fig. 9 shown.

[0043] Quantum chip interface design involves a variety of quantum chip configuration transformation technologies. Superconducting quantum chips have a variety of structures, including structures with couplers and structures without couplers between quantum bits, adjustable frequency bits and non-adjustable frequency bit structures, etc. Designing a universal quantum chip interface is the key to supporting measurement and control and carrying multiple quantum computers. It is necessary to study the characteristics of different quantum chip configurations and design a unified measurement and control interface for chips with different structures. Introduce generalized neighbor bits (including couplers and other unselected calibration bits), and increase or decrease neighbor bits to make the calibration software adapt to a variety of quantum chip configurations.

[0044] In order to adapt to various quantum chip configurations, it is necessary to develop sufficiently flexible quantum chip configuration management to meet the compatibility of various quantum backends. The quantum backend configuration module corresponds to the chip configuration of the quantum computer to meet the adaptation of various quantum chip configurations. Fig.10 As shown in the figure, the quantum backend configuration consists of chip channel configuration, chip channel and line mapping, and line configuration. This configuration structure design completely decouples the quantum backend from the measurement and control environment, and describes the configuration of the quantum backend through the mapping relationship between the chip channel and the physical line. By introducing the generalized neighbor bit structure, quantum chips with and without couplers are uniformly converted into the configuration of quantum chip channels, and couplers are regarded as neighbor bits with fewer channels, so as to adapt to quantum backends of various quantum chip configurations.

[0045] like Fig.11As shown in the figure, the chip channel configuration is divided by quantum groups. Each quantum bit contains four types of channels: drive channel, control channel, detection channel and read channel. Each coupler has only a control channel. If the quantum chip does not contain a coupler, the coupler in the quantum group can be deleted. Each leaf node is the chip channel type and its name, such as Fig.12 shown.

[0046] like Fig.13 As shown in Figure 1, the chip channel and line mapping structure is the same as the chip channel configuration, and is also divided according to quantum groups. The difference is that the leaf nodes are the mapping relationship between the chip channel name and the line name, such as Fig.14 shown.

[0047] like Fig.15 As shown in the figure, each line of the line configuration has different ports for connecting the hardware devices in the measurement and control environment. Each leaf node is configured as follows Fig.16 shown.

[0048] The design of multi-task and multi-user parameter space involves multi-task and multi-user parameter management technology. After completing the hardware environment interface design and adapting to various quantum chip configurations, it is necessary to support multiple users to perform calibration tasks on multiple quantum computers. Different users have their own usage rights for different quantum computers, and they should have their own parameter space on the quantum computers that can be used to prevent data from being overwritten and damaged by others, ensuring the efficient use of the quantum chip calibration software platform. Users edit quantum algorithm circuits on the quantum cloud platform, select a system configuration of a quantum computer, and execute quantum algorithm tasks on the quantum computer, and finally return the quantum algorithm results.

[0049] Multi-task and multi-user parameter management is implemented using independent parameter spaces for different users. In addition to the configurations pre-set by the system administrator, all other parameters of quantum computers used by different users, including experimental parameters, configuration parameters, and characterization calibration results, are stored in their own separate parameter spaces; different quantum computers perform calibration tasks, and data is stored in the parameter space of the user's corresponding quantum computer according to different users. Different users can share the calibration results in their own parameter spaces with other users, or use the calibration results as the system configuration parameters for the user to select the quantum computer using the quantum computing cloud platform to execute quantum algorithms.

[0050] The embodiment of the present invention provides a superconducting quantum computer configuration management system that supports multiple environments and multiple parameter spaces, including multiple superconducting quantum chip configurations, multiple quantum computers, and multiple users executing multiple calibration tasks in their respective independent parameter spaces and storing characterization calibration results. The multi-environment and multi-task superconducting quantum computer configuration management system includes: hardware environment interface design, quantum chip interface design, and multi-task multi-user parameter space. The hardware environment interface design involves multi-environment interface design technology, quantum chip interface design, and multiple quantum chip configuration adaptation technology, and the multi-task multi-user parameter space involves multi-task multi-user parameter management technology. The embodiment of the present invention supports multiple superconducting quantum chip configurations, supports multiple quantum computers, supports multiple users executing multiple calibration tasks in their respective independent parameter spaces, and stores characterization calibration results.
