Chinese Research Team Develops Quantum Chip “Refrigerator”

Recently, Anhui Quantum Computing Engineering Research Center of China efficiently developed the nation’s first quantum chip excessive vacuum storage field and has put it into use. Researchers have referred to as it a “quantum chip refrigerator”.

According to Jia Zhilong, deputy director of Anhui Quantum Computing Engineering Research Center, the quantum chip excessive vacuum storage field is owned by Hefei Benyuan Quantum Computing Technology Co., Ltd., and has three storage cavities, every of which might be operated independently.

At the identical time, it’s outfitted with an clever monitoring system, which might monitor the vacuum diploma in real-time and supply a secure excessive vacuum atmosphere for the chip storage course of. In order to comprehend the entire automation operation of the gear, R&D personnel additionally researched the human-computer interplay interface.

The quantum chip is the core part of quantum computer systems. Different from the standard built-in circuit chips, quantum chips have to undergo advanced system manufacturing processes, reminiscent of ambient temperature, cleanliness, noise, vibration, electromagnetic waves and tiny impurity particles, all of which have an effect on the resultant chip.

Furthermore, superconducting supplies in quantum chips are extremely delicate to the atmosphere. If the atmosphere is lower than customary throughout manufacturing and storage, the supplies simply react with oxygen and water molecules within the air and adsorb varied impurities. The Josephson junction and superconducting capacitance, that are the important thing parts of quantum chips, will age the supplies and subsequently result in a poorer consistency in frequency of the qubits and decrease coherence time of quantum chips. Just like meals is oxidized and rots when uncovered to air, quantum chips can’t be used if they don’t seem to be correctly preserved.

The unique quantum expertise workforce originated on the Chinese Academy of Sciences Key Laboratory of Quantum Information. The workforce has been dedicated to the R&D of quantum computing chips with two manufacturing traces of superconducting and silicon-based semiconductors and has successively produced Wuyuan, the primary quantum chip manufacturing line in China.
