Claim:
1. An on-chip Josephson parametric converter, comprising: a Josephson ring modulator; and a lossless power divider, coupled to the Josephson ring modulator, having a single input port and two output ports for receiving a pump drive signal via the single input port, splitting the pump drive signal symmetrically into two signals that are equal in amplitude and phase, and outputting each of the two signals from a respective one of the two output ports, wherein the pump drive signal excites a common mode of the on-chip Josephson parametric converter, and wherein the lossless power divider comprises at least one microwave filter for at least mitigating any signal leakage from the on-chip Josephson parametric converter through the lossless power divider.
