Abstract
A superconducting circulator device and method of operation. The superconducting circulator device comprises more than two resonators of equal static resonance frequency chained to a ring system by strong coupling. Each of the resonators comprises an adjustable inductor built into the each one of the resonators. The device comprises also a set of ports, each one of the ports coupled to a corresponding one of the more than two resonators, a set of modulators, each one of the modulators positioned adjacently to a corresponding one of the adjustable inductor, and a set of modulation control ports. Each of the modulation control ports is connected to a corresponding modulator of the set of modulators such that each of the modulation control ports controls the related static resonance frequency of the related resonators and such that the ring system is modulatable.
