US Patent Issued to Massachusetts Institute of Technology on Sept. 8 for "Adiabatic CZ gate between fixed-frequency qubits and a tunable fluxonium coupler" (Massachusetts Inventors)

ALEXANDRIA, Va., Sept. 8 -- United States Patent no. 12,731,060, issued on Sept. 8, was assigned to Massachusetts Institute of Technology (Cambridge, Mass.).

"Adiabatic CZ gate between fixed-frequency qubits and a tunable fluxonium coupler" was invented by Roni Winik (Somerville, Mass.), Junyoung An (Cambridge, Mass.) and William D. Oliver (Lexington, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A system and method provide a configurable quantum logic gate. The system includes two fixed-frequency transmon qubits that are capacitively coupled to each other and to a tunable fluxonium coupler. Applying a magnetic flux to the coupler results in a controlled decrease in the ZZ interaction between the two ...
