Corning Assigned Patent

Quantum memory and repeater systems

Corning Incorporated, Corning, NY, has been assigned a patent (9,659,651) developed by Aitken, Bruce Gardiner, Gray, Stuart, Nolan, Daniel Aloysius, Corning, NY, Wang, Ji, Painted Post, NY, and Yang, Jun, Corning, NY, for a “quantum memory systems and quantum repeater systems comprising chalcogenide optical fiber links and methods of storing and releasing photons using the same.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A quantum memory system includes a chalcogenide optical fiber link, a magnetic field generation unit and a pump laser. The chalcogenide optical fiber link includes a photon receiving end opposite a photon output end and is positioned within a magnetic field of the magnetic field generation unit when the magnetic field generation unit generates the magnetic field. The pump laser is optically coupled to the photon receiving end of the chalcogenide optical fiber link. The chalcogenide optical fiber link includes a core doped with a rare-earth element dopant. The rare-earth element dopant is configured to absorb a storage photon traversing the chalcogenide optical fiber link upon receipt of a first pump pulse output by the pump laser. Further, the rare-earth element dopant is configured to release the storage photon upon receipt of a second pump pulse output by the pump laser.

The patent application was filed on July 6, 2016 (15/203,292).
