QUANTUM CHIP AND QUANTUM COMPUTING DEVICE

WIPO Patent Application WO/2024/051002

A1

A quantum chip and a quantum computing device, which are applied to the technical field of quantum computing. The quantum chip comprises a first substrate and a second substrate which are oppositely arranged; a reading cavity is provided in the surface of the side of the first substrate facing the second substrate, quantum bits corresponding to the reading cavity are provided on the surface of the side of the second substrate facing the first substrate, and the reading cavity and the quantum bits form capacitors to be mutually coupled. The structure of a quantum chip body is respectively arranged on two opposite surfaces, so that structural components of the two surfaces are mutually coupled to form the quantum chip body, and the number of the structural components arranged in any surface can be decreased, thereby reducing the wiring difficulty of the structure of the quantum chip body in any surface. In addition, the capacitors are formed between the reading cavity and the quantum bits in the thickness direction to be mutually coupled, so that the coupling strength between the reading cavity and the quantum bits can be greatly improved, and the performance of the quantum bits can be improved.
