Abstract
A Josephson transmission line device comprising a Josephson transmission line consisting of a pair of superconducting layers and a junction layer disposed between the superconducting layers to constitute a Josephson junction; a fluxon stopping position constituted by at least one resistor element in at least a part of the Josephson transmission line; a fluxon driving current source connected to the resistor element; a fluxon generating current source connected to the Josephson transmission line for generating fluxons therein; and an output circuit for extracting the fluxons generated in the Josephson transmission line as output signals. Fluxons generated in the Josephson transmission line can be made to stop at and depart from the stopping positions by selective application of fluxon driving current. Therefore, the Josephson transmission line can, alone or in combination with other such lines, be made to operate as compact, high-speed, low power-dissipation Josephson electronic circuit devices capable of functioning as logic circuits, memories, pulse generators, etc.
