Abstract

A magnetic flux bias circuit includes an input signal line to which an input signal indicating an applied magnetic flux using a digital value is input, a first current control line, a second current control line, and a third current control line to which a clock signal according to the input signal is input, a digital/analog conversion unit converting the input signal into an analog signal using a circuit including a quantum flux parametron circuit on the basis of the input signal input to the input signal line and the clock signal input to the first current control line, the second current control line, and the third current control line, and a magnetic flux application unit applying an applied magnetic flux to a controlled object on the basis of the analog signal output from the digital/analog conversion unit.
