Abstract
A Josephson parametric converter is provided. The Josephson parametric converter includes a multi-Josephson junction ring modulator having arrays of N Josephson junctions arranged in a ring configuration with ring nodes inter-dispersed between the arrays. The multi-Josephson junction ring modulator further has a center node inter-connecting the ring nodes. N is an integer having a value greater than one. The Josephson parametric also includes a first and a second resonator formed from lumped-element capacitors that shunt the multi-Josephson junction ring modulator and respectively enable a first and a second mode of the Josephson parametric converter.
