ALEXANDRIA, Va., July 15 -- United States Patent no. 12,664,455, issued on June 23, was assigned to Xanadu Quantum Technologies Holdings ULC (Toronto).

"Methods for in-situ characterization of gaussian boson sampling (GBS) devices" was invented by Ish Dhand (Ulm, Germany) and Shreya Prasanna Kumar (Ulm, Germany).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method includes causing activation, at a first time, of a first set of squeezed light sources from a plurality of squeezed light sources of a Gaussian boson sampling (GBS) circuit. At a second time after the first time, a first photon statistic is detected at a first output port from a plurality of output ports of the GBS circuit. At a third time after ...
