Abstract
A Josephson-junction logic circuit comprises at least one Josephson-junction logic gate which has a variable threshold-type superconductive quantum interference element. The Josephson-junction logic gate comprises a superconductive inductance loop, and at least two Josephson junctions included in the superconductive loop. At least two current-injection lines connected to the superconductive loop and at least one magnetically coupled line are provided. The magnetically coupled line is placed so as to be magnetically coupled to the inductance. Because of this construction, the number of inputs can be increased. Also, various logical functions can be obtained. Further, various logic circuits can be formed by simply changing the photomask for the wiring between the gates.
