Abstract
A Josephson logic gate device comprises a closed loop of four Josephson junctions, a gate line and a ground line connected to the closed loop at symmetrically opposite points, and a control line connected to the closed loop at the intermediate joint between the gate line and ground line. This logic gate produces a switching function in which the gate current fed to the gate line is steered from the gate to the load by the transition between the zero-voltage state and the voltage state of the device when a control current is supplied into the control line.
