Abstract
A supercurrent memory device comprises a plurality of extended Josephson junctions coupled to one another by having their weak-link layers in contact. Vortices corresponding to one logic state are generated in one pair of junctions, whereas vortices corresponding to a different logic state are generated in another pair of junctions in such a manner that the pairs have at least one junction in common and one junction not in common. Also described are various vortex sensors which may be used in conjunction with the memory device or other extended supercurrent devices.
