The patent abstract shows that the present application provides a quantum chip and a quantum computer, which relate to the field of quantum computing technology, so as to solve the problems of difficulty in manufacturing quantum chips and low yield.
Quantum chips provided by this application include:
- a substrate, M sub-chips, a coupling structure, and a cavity mode suppression structure;
- Each sub-chip includes N qubits, and the M sub-chips are arranged on the surface of the substrate at intervals;
- The coupling structure is used to realize the interconnection between the M sub-chips;
- The cavity mode suppression structure is arranged at the edge of each sub-chip and/or in the gap between the M sub-chips and is used for increasing the cavity mode frequency of the quantum chip.
Among them, M is a positive integer greater than 1, and N is a positive integer greater than or equal to 1. In the quantum chip provided by this application, the quantum chip is composed of M sub-chips, which will effectively reduce the difficulty of production and improve the production yield; and, when a quality defect occurs in a certain sub-chip, it will not cause quality defects. The resulting problems are high costs and waste of resources.
Moreover, Huawei has already explored quantum technology before. On January 12, 2021, Huawei Technologies Co., Ltd. was authorized to publish “a quantum key distribution system, method and device” related patents, with the publication number CN108737083B.
In June 2021, the Ministry of Industry and Information Technology announced the first domestic quantum random number related industry standard “Key Devices and Modules for Quantum Key Distribution (QKD) Based on BB84 Protocol Part 3: Quantum Random Number Generator (QRNG)”, the standard Led by Guodun Quantum, China Academy of Information and Communications Technology, Guoke Quantum, Huawei, Jinan Institute of Quantum Technology, etc. participated in the preparation.
