INCORPORATING ARRAYS OF JOSEPHSON JUNCTIONS IN A JOSEPHSON JUNCTION RING MODULATOR IN A JOSEPHSON PARAMETRIC CONVERTER

摘要

A Josephson parametric converter is provided. The Josephson parametric converter includes a multi-Josephson junction ring modulator having arrays of Josephson junctions arranged in a ring configuration with ring nodes inter-dispersed between the arrays and a center node inter-connecting the ring nodes. The Josephson parametric also includes resonators formed from capacitors that shunt the multi-Josephson junction ring modulator and enable respective modes of the Josephson parametric converter.
