US Patent Issued to The University of Chicago on July 29 for "Controlled photon Fock state generation using arbitrarily weak photonic nonlinearities" (Illinois Inventors)

ALEXANDRIA, Va., July 30 -- United States Patent no. 12,373,721, issued on July 29, was assigned to The University of Chicago (Chicago).

"Controlled photon Fock state generation using arbitrarily weak photonic nonlinearities" was invented by Aashish Clerk (Chicago) and Andrew Lingenfelter (Chicago).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method and system that harnesses extremely weak Kerr-type nonlinearities in a single driven cavity to deterministically generate single photon Fock states, and more general photon-blockaded states are disclosed. The disclosed scheme is effective even for nonlinearities that are much smaller than photonic loss in the cavity. The disclosed scheme generates photon-block...
