US Patent Issued to Homatch.ai on Oct. 21 for "Quantum secure communication protocol and device based on double-helix structure composite multi-layer encoding" (California Inventor)

ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,452,047, issued on Oct. 21, was assigned to Homatch.ai (Milpitas, Calif.).

"Quantum secure communication protocol and device based on double-helix structure 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 helical structure having a ...
