ALEXANDRIA, Va., Aug. 5 -- United States Patent no. 12,700,538, issued on Aug. 4, was assigned to INTERNATIONAL BUSINESS MACHINES Corp. (Armonk, N.Y.).

"Enhancing qubit-qubit interactions between separate chips with spiral resonators" was invented by Aaron Finck (White Plains, N.Y.) and Cihan Kurter (White Plains, N.Y.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Various systems and methods are presented regarding utilizing a spiral resonator to enhance coupling between a first inductor loop and a second inductor loop to enable coupling between a first qubit and a second qubit. Operation of the first inductor loop can be controlled by a flux-tunable TCQ coupler, wherein flux-tuning can adjust operation fro...
