[0002] Current quantum chip calibration software is generally developed for specific chip configurations and measurement and control hardware environments. Due to the significant differences in quantum chip configurations and the varying brands of quantum measurement and control equipment across quantum computers, the adaptability of calibration software is severely limited. With the advancement of superconducting quantum computing technology, each quantum computer will have multiple users, each capable of running multiple calibration tasks. Each calibration task may simultaneously calibrate multiple qubits on a quantum chip, and calibration results from multiple users on the same quantum chip 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 them into quantum algorithm tasks. 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] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, 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 equally within the scope limited by the appended claims of the application.

[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, the 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 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 needs 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 a 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, to support the installation of multiple quantum computers, it is first necessary 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, and the experimental parameters are sent to the measurement and control equipment by the interface, decoupling the quantum calibration experiment from the measurement and control hardware so that the calibration experiment can adapt to different hardware environments.

[0038] Hardware devices refer to the measurement and control equipment of the measurement and control environment, including the parameters required to connect to 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 function, 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 the figure, the JPA control module has 11 reading lines, so it is controlled by 11 JPAs. Each JPA consists of a microwave source channel and a DC source channel, corresponding to the corresponding type of hardware device. Figure 5 As shown in the figure, the quantum analysis module consists of 11 reading and analysis channels. Each quantum analysis channel 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, the quantum bit driving module divides the quantum chip into 11 groups of quantum bits, each group consists of 6 quantum bits. The driving signal of each quantum bit consists of a microwave source channel and an arbitrary waveform generator channel, which correspond to the corresponding type 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 qubits and 11 couplers (the last quantum group does not have a coupler). The flux bias of each qubit 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 type of hardware device.

[0041] In order to adapt the calibration experiment 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 specific measurement and control environment. It has multiple different calibration experiment configurations. Each experimental configuration uses quantum calibration software to characterize and calibrate the quantum chip in the corresponding environment and write the results to the system configuration. Therefore, each experimental configuration in the experimental configuration set corresponds to a system configuration in the system configuration set, thereby supporting a variety of different quantum chip calibration experiments.

[0042] like Figure 8 The experimental configuration management shown is divided into quantum groups. The experimental configuration is 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 experimental configuration version 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 experiment type. Its leaf node configuration items are as follows Figure 9 shown.

[0043] Quantum chip interface design involves various quantum chip configuration transformation technologies. Superconducting quantum chips have a variety of structures, including those with and without couplers between qubits, with and without frequency-tunable bits, and so on. Designing a universal quantum chip interface is key to supporting measurement and control and the deployment of multiple quantum computers. This requires studying the characteristics of different quantum chip configurations and designing a unified measurement and control interface for chips with different structures. Generalized neighbor bits (including couplers and other unselected calibration bits) are introduced, and by adding and removing neighbor bits, the calibration software can adapt to various 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. Figure 10 As shown, the quantum backend configuration consists of chip channel configuration, chip channel-circuit mapping, and circuit configuration. This configuration structure design completely decouples the quantum backend from the measurement and control environment, describing the quantum backend configuration through the mapping relationship between chip channels and physical circuits. By introducing a generalized neighbor bit structure, quantum chips with and without couplers are uniformly converted into quantum chip channel configurations. Couplers are treated as neighbor bits with fewer channels, thus adapting the quantum backend to various quantum chip configurations.

[0045] like Figure 11As shown in Figure 1, 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 only has 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 Figure 12 shown.

[0046] like Figure 13 As shown, 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, as shown in Figure 14 shown.

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

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

[0049] Multi-task, multi-user parameter management is implemented using independent parameter spaces for each user. Beyond the configurations pre-set by the system administrator, all other parameters for each user using the quantum computer, including experimental parameters, configuration parameters, and characterization and calibration results, are stored in their own separate parameter spaces. Calibration tasks performed on different quantum computers are also stored in the parameter spaces of their respective quantum computers, tailored to the user. Users can share calibration results within their own parameter spaces with other users, or use these results as system configuration parameters for their quantum computers when using the quantum computing cloud platform to execute quantum algorithms.

[0050] An 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, the management of multiple quantum computers, and the execution of multiple calibration tasks by multiple users in their respective independent parameter spaces and the storage of characterization and 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 and 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 and multi-user parameter space involves multi-task and multi-user parameter management technology. The embodiment of the present invention supports multiple superconducting quantum chip configurations, supports the installation of multiple quantum computers, supports multiple users in their respective independent parameter spaces to execute multiple calibration tasks and store characterization and calibration results.
