[0002] Quantum computers are physical devices that follow the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information. The main characteristics of quantum computers are fast operation speed, strong information processing capabilities, and a wide range of applications.

Before the quantum chip goes online, it is necessary to test the various parameters of the quantum chip and store the test results. As the scale of quantum chips continues to increase, more and more parameters need to be processed. If we use a list to store and display all quantum chip parameters, we need to spend more time when calling, querying or modifying related parameters, which affects the efficiency of quantum computers in performing quantum computing tasks.

[0040] The specific implementation of the present invention will be described in more detail below in conjunction with the schematic diagram. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.

[0041] In the description of the present invention, it is necessary to understand that the terms "center", "up", "down", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] For some quantum computers currently available on the market, most of them use a combination of a host computer, a quantum computing measurement and control system, and a quantum chip to implement some quantum computing tasks. Generally, the host computer receives the user's quantum computing tasks, processes the quantum computing tasks and forms quantum circuits, and then maps the quantum circuits to the topological structure of the corresponding quantum chip. The quantum circuit contains the quantum logic gates required for this quantum computing task, the measurement operations of the final quantum computing results, and the timing of each operation. When the quantum computing measurement and control system receives the information contained in the quantum circuit, it will convert this information into corresponding instructions so that the corresponding hardware equipment can operate and complete the quantum computing task. Among them, the quantum computing measurement and control system includes a software system and a hardware system. The software system of the quantum computing measurement and control system is used to compile and process the user tasks sent from the host computer, and convert the corresponding user tasks into a language that the hardware system can recognize, so that the hardware system generates corresponding control signals and achieves the purpose of operating and controlling the quantum chip. The solution of the present application interfaces the software system of the quantum computing measurement and control system, directly presents the most direct operation interface to technicians or operators, and directly displays the thermal map of the quantum chip in the software interface. The parameters of the quantum chip can be directly obtained through the thermal map. The parameters here include but are not limited to the driving frequency, driving power, reading frequency, and reading power of the quantum bit or the driving frequency, driving power, reading frequency, and reading power of the adjustable coupler.

[0044] Please refer to Figure 1 , an embodiment of the present invention proposes a quantum computing measurement and control system, including:

[0045] Heat map category selection control, used to configure the heat map category to be displayed;

[0046] Parameter selection interface, used to select the quantum chip parameters to be displayed;

[0047] The heat map display interface is used to display the corresponding heat map in the heat map display interface according to the selected heat map category and quantum chip parameters.

[0048] The difference from the prior art is that a quantum computing measurement and control system proposed in an embodiment of the present invention includes a heat map category selection control, a parameter selection interface, and a heat map display interface. The heat map category selection control is used to configure the heat map category that needs to be displayed, the parameter selection interface is used to select the quantum chip parameters that need to be displayed, and the heat map display interface is used to display the corresponding heat map in the heat map display interface according to the configured heat map category and parameters. The quantum computing measurement and control system proposed in this application directly displays the various parameters of the quantum chip in the interface, without consuming a lot of time in the list to query or modify the relevant parameters of the quantum chip. Displaying the relevant parameters of the quantum chip in the form of a heat map can facilitate technical personnel in this field to understand the quantum chip as a whole, and some parameter drift problems can be directly checked from the heat map. The solution of this application effectively improves the execution efficiency of quantum computers, and at the same time, fills the gap in the prior art.

[0049] It can be understood by those skilled in the art that in a quantum bit expansion architecture based on an adjustable coupler, two quantum bits can be coupled through a fixed capacitive coupling and an adjustable coupler with an adjustable coupling coefficient. The structure of the adjustable coupler is similar to that of the quantum bit, except that the adjustable coupler does not have a quantum state control line and a resonant cavity that can directly read information.

[0050] Specifically, in this embodiment, the heat map category includes quantum bits and adjustable couplers, that is, the heat map category selection control provides two options. When we choose to trigger the quantum bits in the heat map category selection control, the parameter distribution of the quantum bits will be displayed in the heat map display interface; when we choose to trigger the adjustable coupler in the heat map category selection control, the parameter distribution of the adjustable coupler will be displayed in the heat map display interface.

[0051] Specifically, in this embodiment, the structure of the heat map is determined according to the topological structure of the quantum chip.

[0052] Specifically, in this embodiment, the heat map is a two-dimensional depth map, and the depth information in the heat map is the value of the quantum chip parameter selected in the parameter selection interface.

[0053] Specifically, in this embodiment, the specific parameter values ​​of each physical device of the quantum chip in the thermal diagram are displayed in digital form at the corresponding position.

[0054] by Figure 2 and Figure 3 For example, Figure 2When quantum bit is selected in the heat map category selection control, the parameter distribution of quantum bits in the quantum chip shown in the heat map is displayed. Each square corresponds to a quantum bit in the quantum chip, and the specific values ​​of relevant parameters can be filled in the squares, such as the driving frequency, reading frequency, driving power, reading power, decoherence time, energy relaxation time, parameters of frequency control signal, parameters of quantum state control signal, etc. of each quantum bit. Depth information, that is, different colors, will be given in the squares according to the specific values ​​of each parameter. Figure 3 When the adjustable coupler is selected in the heat map category selection control, the parameter distribution of the adjustable coupler in the quantum chip shown in the heat map is shown. Each diamond corresponds to an adjustable coupler in the quantum chip. Similarly, the specific values ​​of the relevant parameters can be filled in the diamond, such as the driving frequency, reading frequency, driving power, and reading power of each adjustable coupler. It should be noted that Figure 2 and Figure 3 The distribution of quantum bits and the distribution of adjustable couplers are determined according to the actual topological structure of the quantum chip. It can be understood by those skilled in the art that a scale for distinguishing color depth information can also be provided in the thermal map. It should be noted that Figure 1-3 This is only an example and should not be considered as any limitation to the present application. There are many other layout forms to choose from.

[0055] Please refer to Figure 1 In this embodiment, the quantum computing measurement and control system further includes:

[0056] A first display control, used to switch the content displayed at the corresponding position of each physical device in the thermal map, wherein when the first display control is in a first trigger state, the corresponding position of each physical device in the thermal map displays the value of the quantum chip parameter;

[0057] When the first display control is in the second trigger state, the corresponding position of each physical device in the heat map displays the number of the corresponding physical device in the quantum chip.

[0058] It should be noted that the first display control can be triggered by a mouse click operation or a touch operation, or even by voice triggering, without limitation here.

[0059] In order to make it easier for the staff in this field to operate and modify the parameters in the quantum chip, the values ​​of the quantum chip parameters shown in the thermal map are editable. The staff can directly click on the relevant parameters and modify them without having to query the relevant parameters in the code or from the data list and modify them, which greatly improves the execution efficiency of the quantum computer.

[0060] Please continue to refer to Figure 1 Specifically, in this embodiment, the quantum computing measurement and control system further includes:

[0061] The configuration export control is used to select whether to export the values ​​of various parameters of the current quantum chip in the form of a configuration file according to the trigger situation.

[0062] Optionally, the configuration file may be exported to a local storage of the terminal or stored in a server in the cloud.

[0063] Optionally, the quantum computing measurement and control system further includes:

[0064] The configuration import control is used to select whether to import the configuration file to configure the various parameters of the current quantum chip according to the trigger situation.

[0065] Those skilled in the art will appreciate that the configuration export control and the configuration import control may be triggered by a mouse click or a touch operation, or may even be voice triggered, and this is not limited here.

[0066] It should be noted that the configuration file mentioned in this embodiment may be a file in other formats including but not limited to ini file, properties file, json file, xml file, yaml file, toml file, HOCON file, plist file, etc., which can be selected according to actual needs and are not described in detail here.

[0067] Specifically, in this embodiment, the quantum computing measurement and control system further includes:

[0068] The second display control is used to switch the color of the heat map.

[0069] Those skilled in the art will appreciate that the second display control may be triggered by a mouse click operation or a touch operation, or may even be voice triggered, and this is not limited here.

[0070] Specifically, in this embodiment, various quantum chip parameters in the parameter selection interface are displayed in a list form.

[0071] The solution of the present application can edit the corresponding quantum chip parameters directly in the heat map. Since the structure of the heat map is highly related to the topological structure of the quantum chip, the relevant parameters can be modified and adjusted more easily. For example, if we need to modify the driving frequency of a certain quantum bit, we can directly see the position of the quantum bit in the heat map and modify its frequency directly at the position of the quantum bit in the heat map. The whole process is less time-consuming and efficient.

[0072] Based on the same inventive concept, an embodiment of the present invention further proposes a quantum computer, comprising a quantum computing measurement and control system as described in any one of the above-mentioned feature descriptions.

[0076] S300: The heat map display interface displays the corresponding heat map in the heat map display interface according to the configured heat map category and parameters.

[0077] Based on the same inventive concept, an embodiment of the present invention further proposes a readable storage medium on which a computer program is stored. When the computer program is executed by a processor, it can implement the operating method of the quantum computing measurement and control system.

[0078] The readable storage medium can be a tangible device that can keep and store the instructions used by the instruction execution device, such as but not limited to an electrical storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device or any suitable combination of the above.

The computer program described here can be downloaded from the readable storage medium to each computing / processing device, or downloaded to an external computer or external storage device through a network, such as the Internet, a local area network, a wide area network and / or a wireless network. The network can include copper transmission cables, optical fiber transmission, wireless transmission, routers, firewalls, switches, gateway computers and / or edge servers. The network adapter card or network interface in each computing / processing device receives the computer program from the network and forwards the computer program for storage in a readable storage medium in each computing / processing device. The computer program for performing the operation of the present invention may be an assembly instruction, an instruction set architecture (ISA) instruction, a machine instruction, a machine-dependent instruction, a microcode, a firmware instruction, a state setting data, or a source code or object code written in any combination of one or more programming languages, including object-oriented programming languages ​​such as Smalltalk, C++, etc., and conventional procedural programming languages ​​such as "C" language or similar programming languages.
