Abstract
A superconductive Josephson circuit device for shift register comprises at least three superconductive quantum interference closed loops magnetically connected to each other in series configuration. The superconductive quantum interference loops each include at least one Josephson junction, having a property of causing a magnetic flux to be quantized as a predetermined unit called 'flux quantum'. The Josephson junction free portions of one loop are arranged in proximity to the Josephson junction free portions of the other loop in a manner to obtain a desired magnetic coupling. Clock current feeding lines for feeding clock currents which bring magnetic flux into the superconductive quantum interference loops are provided to permit a flux quantum number in the loop to be controlled to a predetermined amount (0 or 1). A clock current control circuit controls the supply of the clock current and its timing to permit a flux quantum number '0' or '1' to be shifted as binary information from loop to loop.
