Problems solved by technology

[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 existing superconducting quantum computers have extremely harsh requirements on the working environment and require the use of dilution refrigerators costing millions of dollars. Cool down the quantum computer step by step. The superconducting quantum computer can only operate normally when the temperature is close to absolute zero. Once the temperature is too high, the superconducting quantum computer will stop worki

Abstract

An auxiliary cooling device and method for a quantum computer comprises a first refrigeration unit, a second refrigeration unit, a first cylinder body, an air control switch structure, a third cylinder body, a first supporting frame and a second supporting frame, opening and closing of a heat exchange channel are controlled through the air control switch structure, and the auxiliary cooling devicecan assist a dilution refrigerator in cooling the quantum computer. Power consumption is reduced, and temperature control capability and a temperature emergency protection function are increased.

Description

technical field [0001] The invention relates to the technical field of quantum computer cooling, in particular to an auxiliary cooling device and method for a quantum computer. Background technique [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 existing superconducting quantum computers have extremely harsh requirements on the working environment and require the use of dilution refrigerators costing millions of dollars. Cool down the quantum computer step by step. The superconducting quantum computer can only operate normally when the temperature is close to absolute zero. Once the temperature is too high, the superconducting quantum computer will stop working. It is also necessary to eliminate the noise and radiation from the outside world. If the noise Quantum computer and radiation affect the coherence of qubits, and the data cal...
