Problems solved by technology

[0003] In the process of implementing the technical concept of the present disclosure, the inventor found that the existing technology has the following technical problems: the architecture of a typical superconducting quantum computer is to arrange the control system in a normal temperature (room temperature) environment, and after a large number of control signals are generated in the room temperature area , through the signal line, the signal is sent step by step to the low-temperature area, which will occupy a large number of high-frequency analog signal transmission lines and the wiring position of the refrigerator, and because in most low-temperature areas, the material of the signal line is not superconducting, and A large amount of heat leakage is formed, which makes it difficult for the final refrigerator to achieve a good cooling effect due to the heat leakage of the circuit, which limits the increase in the scale of superconducting quantum computers
