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.
