Abstract
A Josephson parametric converter is provided. The Josephson parametric converter includes a multi-Josephson junction ring modulator having a first, a second, a third, and a fourth node and a first, a second, a third, and a fourth array of N Josephson junctions arranged in a ring configuration with the nodes inter-dispersed between the arrays. The first array is between the first and second nodes, the second array is between the second and third nodes, the third array is between the third and fourth nodes, and the fourth array is between the fourth and first nodes. N is an integer having a value greater than one. The Josephson parametric converter further 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.
