Abstract
Systems and methods are provided for linking two components in a superconducting circuit. A plurality of circuit elements, each comprising one of an inductor, a capacitor, and a Josephson junction, are connected in series on a path connecting the two components. A plurality of tunable oscillators are connected from the path connecting the two components. Each tunable oscillator is responsive to a control signal to tune an associated resonance frequency of the tunable oscillator within a first frequency range, within which the two components are coupled, and within a second frequency range, within which the two components are isolated.
