The patent abstract shows that this application provides a quantum chip and a quantum computer, which involves the field of quantum computing technology to solve the problems of difficulty in making quantum chips and low yield. This application provides a quantum chip including: a substrate, M sub-chips, a coupling structure and a cavity mode suppression structure; each sub-chip includes N quantum bits, and the M sub-chips are arranged on the surface of the substrate at intervals; the coupling structure is used to achieve 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 to increase the cavity mode frequency of the quantum chip; wherein 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 in the present application, the quantum chip is composed of M sub-chips, which can effectively reduce the difficulty of production and improve the production yield; and when a sub-chip has quality defects, it will not lead to problems such as high costs and waste of resources caused by quality defects.
