Abstract: A quantum computing system including plural base configurations each configured including a first quantum bit group configured from first quantum bits arranged so as to form a single column without mutual coupling, a second quantum bit group configured from second quantum bits arranged so as to form a single column with adjacent ones of the second quantum bits coupled together and each of the second quantum bits coupled to the first quantum bit that is arranged in a same row, and a third quantum bit coupled to all of the second quantum bits. The plural base configurations are arranged so as to form a single column with the third quantum bits in adjacent ones of the base configurations coupled together. In a quantum computing circuit configuration, a two-dimensional cluster state or a three-dimensional cluster state is accordingly realized with two-dimensional control wiring, or surface code is accordingly realized with a pseudo two-dimensional superconducting circuit.
