US Patent Issued to Purdue Research Foundation on Feb. 4 for "Optical quantum logic for use in large operational spaces" (Colorado, Indiana Inventors)

ALEXANDRIA, Va., Feb. 5 -- United States Patent no. 12,216,381, issued on Feb. 4, was assigned to Purdue Research Foundation (West Lafayette, Ind.).

"Optical quantum logic for use in large operational spaces" was invented by Andrew Weiner (West Lafayette, Ind.) and Poolad Imany (Boulder, Colo.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method of generating a photon with multiple dimensions includes a step of generating a first photon encoded with quantum information in each of two or more frequency bins and at least one time bin. The method further includes performing a frequency dependent time operation to entangle (i.e. make non-separable) the frequency bins and the time bins in the photon."
