US Patent Issued on Nov. 3 for "Methods and circuits for reading and writing pi-state-induced circulating currents into superconducting circuits containing magnetic Josephson junctions" (Maryland Inventor)

ALEXANDRIA, Va., Nov. 3 -- United States Patent no. 12,784,797, issued on Nov. 3.

"Methods and circuits for reading and writing pi-state-induced circulating currents into superconducting circuits containing magnetic Josephson junctions" was invented by William Robert Reohr (Severna Park, Md.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A write circuit for an MJJ-based memory circuit includes first and second current sources configured to generate first and second currents, respectively. The first current imparting an easy axis magnetic field component on an MJJ in a selected memory cell during a write operation. The second current inducing a third current in the selected memory cell that passes through the...
