Abstract: 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.

Abstract: A quantum key generation system including two photon detector units, two photon entanglement chains extending between the two photon detector units, and a plurality of multicore fiber links each including at least two non-uniform cores structurally configured to provide non-uniform photon propagation delay. Each photon entanglement chain includes at least one quantum repeater structurally configured to entangle a pair of photons and first and second terminating quantum memories optically coupled the quantum repeater using the multicore fiber links such that photons received by the first and the second terminating quantum memories are entangled with photons entangled by the quantum repeater. The first and second terminating quantum memories of each of the two photon entanglement chains form first and second cross-chain quantum repeaters, and the first and the second photon detector units are structurally configured to receive the measurable entangled particles generated by the first and second cross-chain quantum repeaters, respectively.

Abstract: Disclosed are various embodiments of glass structures and the assembly of the same by way of laser welding. In one embodiment, the glass structures may comprise a lightweight mirror or other structure. In constructing a lightweight mirror, a core is assembled by creating laser welded joints between individual ones of a plurality of glass parts. At least one laser access opening is cut out in one or more of the glass parts or plates. In the assembling, various pairs of glass parts are positioned to create abutments therebetween. Further, a laser is directed through at least one laser access opening toward at least one of the abutments to create one or more of the laser welded joints.

Abstract: Glass articles and methods for modifying a composition of a surface portion of the glass article are disclosed. The method includes heating the surface portion of the glass article with a laser beam to a temperature within a range of about 1100?C to about 2200?C such that the heating evaporates one or more metalloids and/or one or more alkali metals present at the surface portion, and modifies the composition of the surface portion such that the surface portion has a lower alkali metals concentration and/or a lower metalloids concentration as compared to a portion of the glass article that is not heated by the laser beam.
