    摘要: Logic elements comprising resettable Josephson junctions cooperating with matched transmission lines have input circuit inductances connected to reversible Josephson devices which are so small that a flux of less than one flux quantum only can be trapped therein preventing the continued circulation of supercurrent in the inductance after removal of the input signals from the associated reversible Josephson junctions.The resettable junctions are designed such that upon removal of the input or control field from the resettable Josephson junctions connected to the transmission line, the a.c. voltage which is generated across said junction, is larger than the time-average d.c. voltage across said junction when switched to its state of normal conductance so that, after removal of the input or control field from said junction, the d.c. voltage is caused to lock back to zero, thus resetting the element. Circuit parameters for achieving resettability without interrupting gate current are given. Logic circuits including AND, OR and NOT circuits are described and the conditions for the operation of such circuits which include both resettable and reversible Josephson devices are also given.
