Compact Josephson interferometer gates are known having an end-fed, inline bridge-type structure. This type of gate has an asymmetric threshold curve. Generally, if such a gate is utilized by switching across the steeper side of the threshold curve, operating margins are quite good, if resonances are neglected. However, in this compact structure, damping of device resonances has not been technologically feasible thus far. Consequently, if the device must be restricted from switching into a resonance, then the resonance peak serves as the lower bound for the gate current (corrected for the load impedance). Since the resonance peak can be as high as approximately 0.
