ABSTRACT:
A polarity-convertible Josephson driver circuit includes first and second driving voltage generating circuits, a driven line, and a load resistor. Each of the first and second driving voltage generating circuits has a loop circuit for forming at least one loop, the loop circuit being constituted by inductances and Josephson junctions so that a plurality of series-connected circuits each constituted by the inductances and the Josephson junctions are parallelly connected between an output point and a reference point, and a control line which has one terminal connected to an input point and the other terminal connected to the output point and is arranged to magnetically coupled to the loop circuit. The driven line connects the output points of the first and second driving voltage generating circuits to each other. A load resistor is inserted in the driven line.
