A qubit assembly includes a first superconducting loop comprising a first Josephson junction and a second Josephson junction, a second superconducting loop comprising the second Josephson junction and a third Josephson junction, and a third superconducting loop comprising the third Josephson junction and a fourth Josephson junction. A flux source is configured to provide a control flux to the second superconducting loop, such that the effective commutation relations between a first quantum operator corresponding to current in the first superconducting loop and a second quantum operator corresponding to current in the third superconducting loop can be changed by changing a magnitude of the control flux provided to the second superconducting loop by the flux source.

Qubit assembly having adjustable current operators

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.
