Description

Technical Field

[0001] The utility model relates to the technical field of quantum, and in particular to a portable plug-in device for a superconducting quantum chip. Background Art

[0002] Superconducting quantum computers are mainly composed of five systems, namely the refrigeration system, chip system, microwave system, cable system, and display system. The chip system refers to the quantum chip and its peripheral packaging structure, which is the core component for realizing quantum computing. The microwave system refers to microwave control units such as cryogenic amplifiers, cryogenic filters, and circulators, which realize the processing of input and output signals. The cable system is a bridge between the chip system and the microwave system. The signal emitted by the microwave system is transmitted to the chip system through the cable system, and the feedback signal of the chip system is transmitted to the display system again through the cable system. In actual work, because different quantum chips need to be debugged, it is necessary to frequently disassemble and maintain the connection to the chip system.

[0003] The existing technology is to directly connect the cables to the quantum chip packaging box. The more BITs there are, the more cable routes there are. For example, taking 20BITs as an example, a maximum of 20 cables must be installed on the quantum chip packaging box. The current plug-in boards of quantum chip packaging boxes have 20 plug-in interfaces on the board, and then connected to the cables. Since the quantum chip packaging box has many holes and they are all in the same plane, and the area of ​​the chip packaging box is relatively small, the interval between each plug-in interface is very small, resulting in a very narrow installation space for the cables. It is easy to touch or damage adjacent components during disassembly and assembly, and it is easy to loosen during connection. If there is a problem with one of the lines, it is difficult to accurately locate and disassemble, and the disassembly and assembly is difficult and inefficient. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1-Figure 3 As shown, in one embodiment, a superconducting quantum chip portable plug-in device is used to connect a signal cable to a chip in a packaging box, thereby realizing input transmission of an external signal to the quantum chip and output transmission of a feedback signal from the quantum chip.

[0026] The specific structure includes:

[0027] The chip packaging box 1, also referred to as a quantum chip packaging box 1, encapsulates a plurality of quantum chips therein. The quantum chip array is arranged inside the chip packaging box 1, and in this embodiment, the distances between adjacent chips are roughly the same, so that it is easier to connect with cables.

[0028] The external signal cable 3 is used for inputting external signals and outputting feedback signals of the quantum chip.

[0029] The transition adapter 2 serves as an intermediate unit for transitionally connecting the external signal cable 3 with the quantum chip. In the present embodiment, its structure is preferably a quadrangular pyramid structure, and a plurality of channels 5 are provided inside the transition adapter 2. The number of the channels 5 is not less than the number of the external signal cables 3 or the quantum chips. An internal signal cable 4 passes through each channel 5. The internal signal cable 4 also serves as a transition unit to input the external signal into the quantum chip, and can also input the quantum chip feedback signal into the external signal cable 3 again through the internal signal cable 4, thereby transmitting it to the outside world.

[0030] As for the transition adapter 2, since it is a tetrahedral structure, one end of it has a larger area and the other end has a smaller area. The end with the smaller area matches the chip packaging box 1. Specifically, the internal signal cable 4 in the smaller end channel 5 is connected to the quantum chip in the chip packaging box 1 through the adapter 2 7. The internal signal cable 4 in the larger end channel 5 of the transition adapter 2 is connected to the external signal cable 3 through the adapter 1 6. Among them, the distribution of the channel 5 in the transition adapter 2 shows the same distribution trend as the tetrahedral structure, so that the installation and removal of the signal cable can be carried out without disassembly in a confined space, so that the disassembly space is enlarged, which is conducive to the disassembly and maintenance of the cable. At the same time, the internal signal cable 4 can be constrained by the tetrahedral, effectively reducing the problem of chaotic cable distribution.

[0031] As for the distribution of the channels 5 , specifically, the distance between the channels 5 gradually decreases from one end to the other end of the transition adapter 2 , so that after the external signal cable 3 is connected to the internal signal cable 4 , the operating space is more ample.

[0032] Furthermore, as for channel 5, it is a straight channel 5, which is more convenient for internal signals to pass in and out.

[0033] Furthermore, adapter 1 6 and adapter 2 7 are respectively fixed to the opposite ends of the transition adapter 2 by bolts, so that adapter 1 6 and adapter 2 7 can be more stably connected to the transition adapter 2 to ensure stability during use.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
