[0021] Among them, the environmental equipment control module is integrally installed inside the equipment cabinet 1 and includes a temperature equipment control module 4, a vacuum equipment control module 5, and a magnetic field equipment control module 6.

The working environment control system for the ion trap quantum computer provided by the embodiments of the present invention can also realize the unified and effective control of the temperature, vacuum, and magnetic field of the ion trap quantum computer, facilitating the operation of the operator.

[0022] Further, the human-machine interaction module includes a touch display screen 2 and a main control machine 3. Among them, the touch display screen 2 is installed outside the equipment cabinet 1 and is arranged on the top of the equipment cabinet 1, facilitating the operator to operate the touch display screen 2. Since the equipment cabinet 1 has a certain height, arranging the touch display screen 2 on the top of the equipment cabinet 1 is convenient for operation.

[0023] Further, universal wheels 12 are provided at the bottom of the equipment cabinet 1, facilitating the movement of the equipment cabinet 1.

[0024] Further, the equipment cabinet 1 is also provided with a cabinet door 11. By opening and closing the cabinet door 11, the maintenance and repair of the main control machine 3 and the environmental equipment control module inside the equipment cabinet 1 can be realized.

[0025] Further, the main control machine 3 is installed inside the equipment cabinet 1 and is electrically connected to the touch display screen 2, and is used for performing human-machine interaction with the operator through the touch display screen 2. Specifically, the main control machine 3 can display the operation data of the environmental equipment control module to the operator through the touch display screen 2, and at the same time can also receive the operation instructions and operation data of the operator on the touch display screen 2 to realize the control of the environmental equipment control module.

[0026] The working environment control system for the ion trap quantum computer provided by the embodiments of the present invention provides a friendly human-machine interaction interface for users by setting up a human-machine interaction module. Users only need to follow the prompts on the human-machine interaction interface to realize the operation of the working environment control system of the ion trap quantum computer. That is, by setting up a human-machine interaction module, functions such as user login management, remote enabling management, experimental data management, experimental operation control, equipment management, and monitoring display can be realized. Among them, the human-machine interaction module is the main control center of the working environment control system of the ion trap quantum computer, equivalent to the brain of the working system. That is, whether the system provided by the present invention can operate orderly and efficiently depends to a certain extent on whether the hierarchical instructions and logical design are reasonable and accurate. Therefore, by setting up a human-machine interaction module, the present invention not only undertakes the requirements of many experimental scenarios, but also has a simple and intuitive operation feeling to meet the demands of quantum experimenters for experiments.

[0027] More specifically, the touch display screen 2 is provided with a one-key operation area, a main display area, an icon display area, a preset area, an operation log storage area, a device management area, a login and unlocking area, and a remote control area. During use, the user can directly perform operations in the corresponding areas of the touch display screen 2 of the human-computer interaction module, thereby realizing the control of the environmental equipment control module and more intuitively calling up each sub-module or functional area. At the same time, the experimental process can also be dynamically displayed directly through the touch display screen 2. For example, the user can log in to the system or unlock the system by entering the login account and password through the login and unlocking area; relevant data is displayed to the user through the main display area; the user can start or stop the system through the one-key operation area, etc.

[0028] The working environment control system for an ion trap quantum computer provided by the embodiment of the present invention, by setting up a human-computer interaction module, can not only meet the requirements of many experimental scenarios, but also have a simple and intuitive operation feeling, meet the operator's demands for the experiment, simplify the operation, solve the problems such as complex installation caused by device diversity in the prior art, and also solve the problem that the existing operator cannot simultaneously operate and control multiple devices.

[0029] Before the working environment control system for an ion trap quantum computer provided by the embodiment of the present invention is used, first turn on the main power switch to connect the main control machine 3 and the environmental equipment control module inside the equipment cabinet 1 to the power supply. Then, the operation control of the environmental equipment control module inside the equipment cabinet 1 is realized through each touch button or button, etc. on the interface displayed by the touch display screen 2 of the human-computer interaction module. At the same time, during the system control process, the entire experimental process is also displayed through the touch display screen 2, which is convenient for the operator to view intuitively.

[0030] In addition, for the convenience of the operator's operation, various buttons and switches are also provided on the equipment cabinet 1 of the working environment control system for an ion trap quantum computer provided by the embodiment of the present invention, which are used to realize the on-off control of the main control machine 3 inside the corresponding equipment cabinet 1. For example, by opening corresponding openings on the cabinet door 11 of the equipment cabinet 1, and then extending the corresponding buttons or switches to the outside through the corresponding openings, in this way, the start and stop of the main control machine 3 inside the equipment cabinet 1 can be realized without opening the cabinet door 11.

[0031] Furthermore, the working environment control system for an ion trap quantum computer provided by an embodiment of the present invention further includes a remote management center. Among them, the main control unit 3 is communicatively connected to the remote management center to realize data interaction with the remote management center and provide remote management functions. Specifically, a communication module is integrally provided inside the equipment cabinet 1 or inside the main control unit 3. The main control unit 3 is communicatively connected to the remote management center through the communication module, and is used to receive the control signals issued by the remote management center and upload the system operation status data to the remote management center for backup for subsequent viewing.

[0032] Furthermore, the main control unit 3 is also electrically connected to the temperature equipment control module 4, the vacuum equipment control module 5, and the magnetic field equipment control module 6 of the environmental equipment control module. By obtaining the real-time operation status data of the temperature equipment control module 4, the vacuum equipment control module 5, and the magnetic field equipment control module 6, early warning analysis of the working environment of the ion trap quantum computer is realized, and the operation status data and the early warning analysis results are displayed through the touch display screen 2. For example, when the operation of a certain control module is abnormal or fails, the working environment of the ion trap quantum computer may correspondingly be abnormal, and the staff can be reminded in time for maintenance or repair.

[0033] Furthermore, a switch is also provided inside the equipment cabinet 1. Among them, the main control unit 3 is also connected to the temperature equipment control module 4, the vacuum equipment control module 5, and the magnetic field equipment control module 6 through the switch to respectively issue corresponding control signals to each control module. Even further, the main control unit 3 is also electrically connected to the switch through a control bus to realize data interaction.

[0034] Even more further, a serial server and a plurality of IO relays are also provided inside the equipment cabinet 1. Since the interface of the switch is generally an RJ45 interface, while the environmental equipment control module is generally an IO interface. Therefore, the working environment control system for an ion trap quantum computer provided by an embodiment of the present invention also realizes interface conversion by setting a serial server, so as to electrically connect the main control unit 3 to the temperature equipment control module 4, the vacuum equipment control module 5, and the magnetic field equipment control module 6 in the environmental equipment control module. That is, the main control unit 3 is connected to the serial server through the switch, and the serial server is electrically connected to the corresponding environmental equipment control module through the IO relay. The conversion between the RJ45 interface and the IO interface is realized through the serial server, which is convenient for equipment control.

[0035] By setting a serial server and an IO interface inside the equipment cabinet 1, the connection between the main control unit 3 and the environmental equipment control module is realized, and the interface conversion is realized in combination with the serial server, improving the adaptability of various control modules.

[0036] Furthermore, the vacuum equipment control module 5 is used to control the vacuum in the working environment of the ion trap quantum computer. That is, the vacuum equipment control module 5 is electrically connected to the vacuum degree adjustment equipment and is used to control the operation of the vacuum degree adjustment equipment to adjust the vacuum degree of the working environment of the ion trap quantum computer. Specifically, the vacuum equipment control module 5 includes an aspirator pump controller, an ion pump controller, and a molecular pump controller. Among them, the aspirator pump controller is electrically connected to the aspirator pump and is used to control the working state of the aspirator pump. The ion pump controller is electrically connected to the ion pump and is used to control the working state of the ion pump. The molecular pump controller is electrically connected to the molecular pump and is used to control the working state of the molecular pump. Among them, the aspirator pump, the ion pump, the molecular pump, etc. all belong to the vacuum degree adjustment equipment. In the actual application process, the vacuum degree adjustment equipment can be adjusted according to actual needs. Correspondingly, the vacuum equipment control module 5 can also be provided with corresponding controllers accordingly.

[0037] By setting various controllers, the working environment of the ion trap quantum computer is evacuated to achieve an ultra-high vacuum environment. For example, the vacuum degree adjustment equipment is set as a front-stage scroll pump, a secondary molecular pump, an ion pump, etc. That is, through the operation of the three-stage pump group, pre-evacuation and main evacuation are achieved, and the ultra-high vacuum degree can reach 10 -12 mbar.

[0038] More specifically, the working environment control system for the ion trap quantum computer provided by the embodiment of the present invention further includes an environment detection module. Among them, the environment detection module is installed in the working environment of the ion trap quantum computer to detect the environmental data in the working environment of the ion trap quantum computer. Specifically, the environment detection module includes a vacuum degree detection module, a temperature detection module, and a magnetic field detection module. Among them, the vacuum degree detection module, the temperature detection module, and the magnetic field detection module are respectively connected to the main control machine 3 and are used to upload the corresponding detection data to the main control machine 3, so that the main control machine 3 can judge whether there is an abnormality in the working environment of the ion trap quantum computer according to the detection data and the preset threshold value, so as to send out an abnormality notice in time.

[0039] By distributing and installing each environment detection module in the working environment of the ion trap quantum computer, the monitoring of the working environment of the ion trap quantum computer is realized, and further the feedback control of the vacuum equipment control module 5, the temperature equipment control module 4, and the magnetic field equipment control module 6 is realized.

[0040] That is, the vacuum degree detection module is installed in the working environment of the ion trap quantum computer and is used to detect the vacuum degree of the working environment of the ion trap quantum computer and send it to the main control unit 3, so that the main control unit 3 can implement feedback control on each controller in the vacuum equipment control module 5 according to the above detection data, and realize providing a vacuum environment with a corresponding vacuum degree for the ion trap quantum computer, which is beneficial to the operation of the ion trap quantum computer. Among them, the vacuum degree detection module can be implemented by a vacuum gauge.

[0041] In addition, during the control process, the main control unit 3 also makes a warning judgment based on the vacuum degree data, and displays the vacuum degree data and the warning analysis result to the operator through the touch display screen 2 for the operator to analyze and view, meeting various requirements of the user for experiments and safety guarantees. More specifically, the present invention also obtains the operation status data of each vacuum equipment control module 5 through the main control unit 3 and analyzes according to the operation status data to realize the rotational speed control, electrical parameter control, and control curve adjustment, etc. of each vacuum degree adjustment device. The vacuum degree adjustment device can be set according to actual needs, and is not limited to the devices given in this embodiment.

[0042] Furthermore, the temperature equipment control module 4 is electrically connected to the temperature adjustment device and is used to control the working state of the temperature adjustment device to realize the adjustment of the working temperature of the ion trap quantum computer. Specifically, the temperature equipment control module 4 includes a temperature controller. Specifically, the temperature controller is connected to the refrigerator of the temperature adjustment device and is used to control the operation of the refrigerator, thereby realizing the control of the working environment temperature of the ion trap quantum computer. More specifically, during the actual use process, a chiller is also used to provide a cold source for the refrigerator. For example, a helium chamber is set in the working space of the ion trap quantum computer, the refrigerator is arranged in the helium chamber, and the ion trap quantum computer is fixedly arranged at the cold head on the outer surface of the helium chamber. In this way, the refrigerator can conduct the cold source to the ion trap quantum computer through the helium in the helium chamber, realizing the temperature control of the working environment of the ion trap quantum computer. That is, the cold source of the refrigerator will transfer heat to the ion trap quantum computer through helium, avoiding the direct contact between the ion trap quantum computer and the refrigerator from affecting the operation of the ion trap quantum computer. In addition, when cooling the ion trap quantum computer, closed-cycle refrigeration can also be adopted to effectively reduce the thermal radiation effect, provide temperature balance PID control, maintain the internal temperature of the ion trap quantum computer, and make it reach ultra-low temperature to meet the working requirements of the ion trap quantum computer. In addition, the refrigerator also includes a compressor, and through the operation of the compressor, the cold source is further transported into the working environment of the ion trap quantum computer to provide an ultra-low temperature working environment for the ion trap quantum computer.

[0043] Furthermore, a temperature detection module is used to detect the working environment temperature data of the ion trap quantum computer and send it to the main control unit 3, so that the main control unit 3 can implement feedback control of the temperature controller according to the detected temperature data, and perform early warning analysis based on the detected temperature data and display the early warning analysis results and detection data to the user through the touch display screen 2. The temperature detection module can be implemented by using a temperature sensor. For example, the temperature sensor is arranged at the cold head of the refrigerator to detect whether the temperature of the refrigerator meets the requirements.

[0044] Further, a magnetic field device control module 6 is electrically connected to the magnetic field intensity adjustment device and is used to control the magnetic field intensity of the ion trap quantum computer during operation. Specifically, the magnetic field device control module 6 includes a magnetic field device controller. Among them, the magnetic field device controller is electrically connected to the magnetic field generator and is used to control the magnetic field generator to provide a corresponding magnetic field for the ion trap quantum computer. The magnetic field generator is a magnetic field intensity adjustment device and can adjust the magnetic field intensity of the working environment of the ion trap quantum computer. Specifically, for example, the magnetic field generator includes a constant current source, and the constant current source is controlled by the magnetic field device controller to provide a magnetic field environment for the ion trap quantum computer.

[0045] Similarly, a magnetic field detection module is used to monitor the magnetic field intensity of the working environment of the ion trap quantum computer to implement feedback control and early warning analysis of the magnetic field device controller, etc., and display relevant data through the touch display screen 2. The present invention can provide symmetric compensation for external interference while providing three-dimensional magnetic field measurement. The magnetic field detection module can be implemented by using a magnetometer, etc.

[0046] Furthermore, the environmental detection module further includes an out-of-trap environmental detection module, which is arranged outside the working environment of the ion trap quantum computer and is electrically connected to the main control unit 3. It is used to detect the external environmental data of the ion trap quantum computer and send it to the main control unit 3, so that the main control unit 3 can make an early warning judgment on the operation of the ion trap quantum computer according to the external environmental data and early warning data of the ion trap quantum computer, and display it to the operator through the touch display screen 2. Among them, the external environmental data includes relevant data such as temperature and humidity. The present invention not only monitors the working environment of the ion trap quantum computer and performs feedback adjustment, etc., but also needs to monitor the external working environment of the ion trap quantum computer to implement early warning analysis of the operation of the ion trap quantum computer, timely discover abnormalities, and ensure the working safety of the equipment.

[0047] Specifically, the out-of-trap environmental detection module can be set to perform different detections according to actual needs, and can be implemented by setting various sensors, such as temperature sensors, humidity sensors, etc., to obtain environmental data outside the operation of the ion trap quantum computer, so as to timely judge whether there is an abnormality in the operation of the ion trap quantum computer according to the preset values.

[0048] Furthermore, a power distribution module is also provided inside the equipment cabinet 1. The power distribution module is used to connect to an external power supply and convert it into various power supplies required by the system. Since in the actual use process, the voltages and types of the power supplies required by different devices are different, therefore, by setting the power distribution module, the conversion of the power supply is realized to ensure the normal operation of each device in the whole system. By setting the power distribution module, a power source is provided for the working environment of the ion trap quantum computer, ensuring that the ion trap quantum computer can operate safely, reliably, with protection and backup.

[0049] Even further, the power distribution module includes a UPS power supply, a plurality of short-circuit protection devices and a plurality of AC contactors. One end of the UPS power supply is connected to the external power supply through three-phase five-wire, and the other end is electrically connected to each short-circuit protection device. Each short-circuit protection device is respectively electrically connected to the temperature device control module 4, the vacuum device control module 5, and the magnetic field device control module 6 inside the equipment cabinet 1 through a corresponding AC contactor to provide the corresponding power supply. Among them, the short-circuit protection devices and AC contactors are used to protect the power supply of each control device, ensuring the stable power supply of the control device and abnormal power-off protection. That is, each control device is provided with a short-circuit protection device and an AC contactor, and the short-circuit protection device provides short-circuit protection for it to ensure the stability of the power supply.

[0050] In addition, for the power distribution module, a protective layer, an energy-saving control layer, a UPS management layer, an output clean layer, etc. can also be set according to requirements. Specifically, the corresponding devices of each layer can be set according to actual requirements, and the present invention will not make specific introductions. The power distribution module can provide a safe, reliable, protected and backup power supply system for the operation of the ion trap quantum computer for the company.

[0051] Furthermore, the working environment control system for the ion trap quantum computer provided by the embodiment of the present invention also sets various layers of boards inside the equipment cabinet 1, and places them on the corresponding layer boards according to the differences of each control module, so that the orderly connection between each control module inside the equipment cabinet 1 and the main control machine 3 is avoided, and the installation chaos is avoided, which affects subsequent maintenance.
