Abstract

Josephson logic circuits using fluxoid quantization in a one-junction interferometer to represent logical states have been fabricated from thin films of Nb by means of photolithography, electron beam lithography, and reactive ion etching. A variable thickness bridge is used as a Josephson junction in the one-junction interferometer. The logic circuits have shown AND and OR logic functions.
