Circuit apparatus and control method

Abstract

A circuit apparatus includes: a plurality of parametric oscillators; a magnetic field generator provided for each of the parametric oscillators; a coupler provided for each of the parametric oscillators; a signal generator configured to output a phase-locking signal incident on the parametric oscillator via the coupler and a pump signal incident on the magnetic field generator; and a controller configured to control the signal generator, wherein the parametric oscillator includes a variable element, the magnetic field generator applies a magnetic field to the variable element, the signal generator includes output channels for the phase-locking signal, a number of the output channels being fewer than a number of the parametric oscillators, and the controller controls a phase difference between the phase-locking signal and the pump signal.
