ALEXANDRIA, Va., Sept. 3 -- United States Patent no. 12,408,562, issued on Sept. 2, was assigned to INTERNATIONAL BUSINESS MACHINES Corp. (Armonk, N.Y.).
"Monolithic silicon Josephson junctions for superconducting qubits" was invented by Nicholas Torleiv Bronn (Long Island City, N.Y.), Thorsten Muehge (Budenheim, Germany) and Mark Mattingley-Scott (Heidelberg, Germany).
According to the abstract* released by the U.S. Patent & Trademark Office: "A monolithic silicon Josephson junction can be fabricated from a silicon wafer using semiconductor technologies such as gas immersion laser doping and smart cut technology. Rather than using a superconducting metal for the junction electrodes, silicon that has been highly doped with boron can serve...
