ABSTRACT:
A superconducting circuit comprises a quantum flux parametron. In the superconducting circuit, at least one of two Josephson devices is a voltage controlled superconducting device, the critical current of which can be controlled by applying a voltage. By adjusting the applied voltage, the critical currents of the two Josephson devices can be equalized. If an input signal is used as the applied voltage, the input signal can be isolated from an output signal. And further, if both critical currents of the two Josephson devices are increased after an input signal is supplied, the input signal can be stably amplified.
