Abstract
A device comprises a superconducting parametric interferometric circuit, which comprises a signal input port and a signal output port, and a first parametric mixing circuit and a second parametric mixing circuit coupled in parallel between the signal input port and the signal output port. The signal input port configured to receive an input signal having a first frequency. The first parametric mixing circuit is configured to convert the input signal to a first output signal having a second frequency, and the second parametric mixing circuit is configured to convert the input signal to a second output signal having the second frequency. The superconducting parametric interferometric circuit is configured to constructively combine the first and second output signals at the signal output port to generate an output signal having the second frequency, and provide isolation of the signal input port from a signal which is present at the signal output port.
