Abstract
A quantum gate device includes a first superconducting circuit which includes at least one of Josephson devices in an annular circuit including a superconducting wire and resonates at a first resonance frequency, a second superconducting circuit which includes at least one of Josephson devices in an annular circuit including a superconducting wire and resonates at a second resonance frequency, a connection unit which includes a capacitor and a superconducting wire provided at each electrode of the capacitor and connects the first and second circuits, a magnetic field application means applying a magnetic field to one or both of the first and second circuits, a quantum gate control electromagnetic wave irradiation unit irradiating one of the first and second circuits with a control electromagnetic wave, and an unnecessary transition suppression electromagnetic wave irradiation unit irradiating one of the first and second circuits with an unnecessary interaction suppression electromagnetic wave.
