Abstract

Injecting a bias voltage at only one end of a long Josephson junction provides input/output isolation, permitting the device to act as a shooter, and when interconnected with similar devices to perform combinatorial logic. A soliton device (long junction) transmits solitons in either direction, depending on whether a pulse is applied at one or the other end. This poses a problem when it is desired to collect solitons emanating from other circuits. If solitons are injected into a string of devices (long junctions), they propagate in both directions, activating circuits that should normally not be activated. In other words, the device lacks input/output isolation. A device with input/output isolation (the shooter) is shown in Fig. 1.
