Abstract
A superconducting logic circuit has a first and a second one-junction SQUID's (superconducting quantum interference device) connected by a superconducting inductor, the junction of the second SQUID having a larger critical current than that of the first SQUID, the inductance of the second SQUID being smaller than that of the inductor, and a signal applied to the first SQUID is unidirectionally transmitted to the second SQUID by applying bias currents to the junctions of the two SQUID's.
