Title: Multiple weak-link SQUID

Abstract

The disclosed SQUID (Superconducting quantum interference device) comprises two superposed superconductive layers with an insulating layer therebetween. A plurality of holes through the insulating layer filled with superconductive material form weak links between the superconductive layers. One or more control lines superposed with respect to the superconductive layers provide magnetic flux through the area between the weak links to control the zero voltage supercurrent flowing through the weak links from one of the superconductive layers to the other thereby providing the switching function for Josephson superconductive circuits.
