ALEXANDRIA, Va., June 4 -- United States Patent no. 12,322,524, issued on June 3, was assigned to NORTHROP GRUMMAN SYSTEMS Corp. (Falls Church, Va.).
"Flux-trapping magnetic films in superconducting circuits" was invented by Daniel Robert Queen (Kensington, Md.).
According to the abstract* released by the U.S. Patent & Trademark Office: "One example includes a superconducting circuit. The circuit includes superconducting circuitry fabricated in a circuit layer. The circuit layer includes a first surface and a second surface opposite the first surface. The circuit also includes a flux moat comprising a dielectric material formed in the circuit layer. The flux moat can be configured to trap a magnetic flux as the superconducting circuit is ...
