ALEXANDRIA, Va., June 2 -- United States Patent no. 12,647,260, issued on June 2, was assigned to Homatch.ai (Milpitas, Calif.).

"Quantum secure communication protocol and device based on composite multi-layer encoding" was invented by Mingjun Wang (Saratoga, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for secure quantum communication includes generating a photon. The method includes modulating at least two quantum state dimensions selected from the group consisting of orbital angular momentum (OAM), polarization, and phase of the photon to form a composite quantum state. The method includes directing the photon to an emission point on a structure having a defined spatial coordinate corres...
