Abstract
A superconducting quantum circuit apparatus, including: two or four Josephson parametric oscillators, JPOs, each including: a SQUID; and a pump line, with a pump signal supplied thereto, providing a magnetic flux penetrating through the loop of the SQUID, the JPOs oscillating parametrically in response to the pump signal supplied to the pump line; a coupler to couple the two or four JPOs; and a phase adjuster that varies a relative phase between or among pump signals supplied respectively to the pump lines of the two or four JPOs for parametric oscillation, to vary a strength of a two-body or four-body interaction.
