Title:
QUANTUM COMPUTING SYSTEM AND USE METHOD FOR QUANTUM COMPUTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/216278
Kind Code:
A1
Abstract:
This quantum computing system is provided with a plurality of basic structures configured to include: a first quantum bit group comprising first quantum bits that are arranged in one column and not connected to each other; a second quantum bit group comprising second quantum bits that are arranged in one column, said second quantum bits being connected to the second quantum bits adjacent thereto and connected to a first quantum bit arranged in the same row; and a third quantum bit connected with all of the second quantum bits. The plurality of basic structures are arranged in one column, and said quantum computing system is provided with a quantum computing circuit obtained by connecting the third quantum bits of adjacent basic structures. In the resulting quantum computing circuit configuration, a two-dimensional cluster state or a three-dimensional cluster state is achieved using control wiring on a two-dimensional plane, or surface code is achieved using a quasi-two-dimensional superconducting circuit.
