[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] Reference below Figure 1 An ion trap quantum computer 100 according to an embodiment of the present invention is described.

[0030] like Figure 1 As shown, the ion trap quantum computer 100 according to an embodiment of the present invention includes: a first cabinet 10 and a second cabinet 20 .

[0031] Among them, the first cabinet 10 contains an electronic control unit 30, and the second cabinet 20 contains a computing unit 40. The multiple modules in the computing unit 40 include at least all modules of the ion trap quantum computer 100 that need to be connected through optical fibers, and the electronic control unit 30 and the computing unit 40 are electrically connected through a cable detachably arranged between the first cabinet 10 and the second cabinet 20, so that power is supplied to the computing unit 40 through the electronic control unit 30 and data exchange is carried out.

[0032] Specifically, the electronic control unit 30 and the computing unit 40 are respectively arranged in the first cabinet 10 and the second cabinet 20, so that the ion trap quantum computer 100 is constructed as a split structure. When the ion trap quantum computer 100 is transported, the first cabinet 10 and the second cabinet 20 can be transported separately. Through the split structure, the ion trap quantum computer 100 can be transported in batches and electrically connected through cables after transportation.

[0033] It can be understood that the first cabinet 10 and the second cabinet 20 that are carried in batches are smaller in size than the traditional integrated ion trap quantum computer 100 each time, which can reduce the difficulty of transportation and improve the convenience of transportation. The modules in the ion trap quantum computer 100 that need to be connected by optical fiber and some modules that are connected by cables are integrated into the computing unit 40, and the electronic control unit 30 is connected to the computing unit 40 only by cables. That is, after being carried in batches, the first cabinet 10 and the second cabinet 20 are connected by cables that are detachably provided thereon, and the assembly of the ion trap quantum computer 100 can be completed.

[0034] Therefore, during the transportation of the ion trap quantum computer 100 , there is no need to plug or unplug optical fibers between modules that need to be connected via optical fibers, which ensures that the optical fiber state remains unchanged, thereby improving the working stability of the ion trap quantum computer 100 .

[0035] According to the ion trap quantum computer 100 of an embodiment of the present invention, a first cabinet 10 and a second cabinet 20 are provided, and modules that need to be connected by optical fibers are integrated into a computing unit 40, which is provided in the second cabinet 20. On the one hand, the split ion trap quantum computer 100 can reduce the difficulty of transportation, improve the convenience of transportation, and comply with the miniaturization trend of quantum computers; on the other hand, during transportation, the optical fibers in the ion trap quantum computer 100 do not need to be plugged in or unplugged, and the optical fiber state can be maintained unchanged, thereby improving the working stability of the ion trap quantum computer 100 and ensuring its long-term working stability.

[0036] It should be pointed out that in the prior art, after the ion trap quantum computer 100 is divided into multiple functional modules, the signal connection part is generally used as a detachable node, and each module is provided with an interface for electrical connection with the outside world and data interaction. Multiple modules are generally connected through cables or optical fibers, and the length of the cable and the number of cable interfaces are greater than the number of optical fiber interfaces. Therefore, the conventional design will select an interface type with a small number of interfaces as the external interface (that is, the interface between the first cabinet 10 and the second cabinet 20). The inventor of the present invention found that the optical fiber interface as an external interface has the technical problems mentioned in the background technology, and proposed the present invention based on the technical problems.

[0037] like Figure 1 As shown, according to some embodiments of the present invention, the electronic control unit 30 includes: a measurement and control module 31 and a power supply module 32. The power supply module 32 supplies power to the computing unit 40 and the measurement and control module 31 through a cable. The measurement and control module 31 interacts with the computing unit 40 through a cable.

[0038] Specifically, the power supply module 32 is used to supply power to the computing unit 40 and the measurement and control module 31, and can improve power-off protection, including but not limited to a UPS submodule, a DC submodule, etc., while the measurement and control module 31 is used to monitor the status of each module in the computing unit 40, collect and analyze information, and control the operation of the module, etc., including but not limited to a signal generation submodule, a feedback locking submodule, a power amplification submodule, a precision DC submodule, a signal detection submodule, a laser control submodule, a vacuum pump control submodule, and a software submodule.

[0039] In this way, the power supply module 32 and the measurement and control module 31 used for power supply and data interaction do not need to be connected to the computing unit 40 through optical fibers, and the above-mentioned technical effects can be achieved.

[0040] In some embodiments, the computing unit 40 includes: a vacuum module 41, a magnetic field module 42 and a trap chip module 42. The vacuum module 41 provides a vacuum environment for the trap chip module 42, the magnetic field module 42 is used to provide a magnetic field in a specific direction, and the trap chip module 42 is used to maintain the electric field and trap ions for calculation.

[0041] Among them, the trap chip module 42 includes but is not limited to trapped ions, trap chips, chip holders, vacuum cables, targets, hot furnaces, etc.; the vacuum module 41 includes but is not limited to vacuum chambers, vacuum windows, ion pumps, air pumps, etc.; the magnetic field module 42 includes but is not limited to permanent magnets and magnetic field coils.

[0042] That is to say, the vacuum module 41 , the magnetic field module 42 and the well chip module 43 define a first scope 40 a as the core part of the computing unit 40 .

[0043] like Figure 1 As shown, the computing unit 40 also includes: a laser module 44 and an electric field module 45. Both the laser module 44 and the electric field module 45 directly act on the trap chip module 42. The laser module 44 is used to cool and manipulate the ion state, and the electric field module 45 provides an electric field for trapping ions.

[0044] Among them, the laser module 44 includes but is not limited to a laser head, a frequency stabilization submodule, an optical power stabilization submodule, an optical modulation submodule, etc.; the electric field module 45 includes but is not limited to a radio frequency cavity submodule and a DC filter submodule.

[0045] In addition, the computing unit 40 also includes: a fluorescence collection module 46, which is used to collect the ion fluorescence generated by the trap chip module 42, including but not limited to a photon counter, an imaging lens, and a CCD camera, and the electric field module 45, the laser module 44, the shielding module 47 and the fluorescence collection module 46 define a second scope 40b.

[0046] As a result, the loading laser generated by the laser module 44 and other laser light paths within the first scope 40a and the second scope 40b can share a window, reducing the number of windows. This is not only beneficial to ensuring the magnetic shielding performance of the ion trap, but also facilitates the miniaturization and compactness of the ion trap quantum computer 100.

[0047] like Figure 1 As shown, the computing unit 40 further includes a shielding module 47, which acts on the first scope 40a. Thus, the shielding module 47 can magnetically shield at least the first scope 40a, thereby improving the operating stability of the ion trap quantum computer 100.

[0048] The shielding module 47 includes but is not limited to a magnetic shielding cover.

[0049] like Figure 1 As shown, according to some embodiments of the present invention, the ion trap quantum computer 100 further includes: a shock absorbing module 60 and a temperature control module 50, wherein the shock absorbing module 60 is arranged between the computing unit 40 and the second cabinet 20 to isolate environmental vibrations; and a temperature control module 50, wherein the temperature control module 50 is used to maintain the stable working temperature of the computing unit 40.

[0050] That is to say, a shock absorbing module 60 and a temperature control module 50 are also provided in the second cabinet 20. The shock absorbing module 60 includes but is not limited to structures such as shock absorbers and buffer plates, and the temperature control module 50 includes but is not limited to structures such as insulation surfaces and heating films.

[0051] Thus, modules that are more sensitive to temperature fluctuations, vibration interference, and electromagnetic interference are integrated into the first scope 40a and the second scope 40b, and the shock absorption module 60 is used to avoid vibration and reduce vibration interference, and the temperature control module 50 is used to control the temperature and reduce temperature fluctuations. On the one hand, the working stability of the ion trap quantum computer 100 can be effectively improved. On the other hand, components that are more sensitive to temperature fluctuations, vibration interference, and electromagnetic interference can be uniformly controlled in the second cabinet 20, which can reduce the difficulty of control, reduce the number of control structures and space occupancy, and further reduce the space occupancy and cost of the ion trap quantum computer 100.

[0052] As you can understand, the first cabinet 10 houses the measurement and control module 31 and the power module 32, while the second cabinet 20 houses the remaining modules. The first and second cabinets 10, 20 are connected only by cables, not optical fibers. This not only reduces the space occupied by the first and second cabinets 10, 20, but also requires only one damping module 60 and one temperature control module 50, saving space and cost.

[0053] More importantly, the optical fiber remains stationary before and after transport, ensuring the long-term stability of the optical signal. The shielding module 47 magnetically shields only the specific module requiring shielding (the first scope 40a), reducing the volume and cost of shielding material and facilitating module maintenance. The measurement and control module 31 and power module 32 within the first cabinet 10 are relatively insensitive to ambient temperature, vibration, and electromagnetic interference, so they only need to meet normal industrial design requirements.
