1. A device, comprising:
a Josephson parametric converter (JPC) comprising:
a Josephson ring modulator (JRM) having nodes respectively between sets of Josephson junctions; and
an impedance matching circuit network operatively connected across a pair of the nodes, wherein the impedance matching circuit network increases a frequency bandwidth of the JPC device.
