Abstract: A superconducting device includes a frequency tunable device comprising a first conductive pad and a second conductive pad that are connected to each other by a Josephson junction, a ferromagnetic structure disposed at a predetermined distance apart from the first and second conductive pads, a control line located below the ferromagnetic structure, and a control circuit configured to control a resonant frequency of the frequency tunable device by controlling current flowing through the control line.
