Abstract: An apparatus comprises a fiber input, the fiber input comprising a plurality of input fiber cores receiving a plurality of input optical signals. The apparatus also comprises an optical signal manipulation device that is one of a fiber mode shuffler, a fiber coupler, a power splitter, or a 90-degree optical hybrid. The optical signal manipulation device comprises an input aperture held in spaced relation to the fiber input, an output aperture, and a plurality of metasurfaces that manipulate phase profiles of the plurality optical signals to generate a plurality of output optical signals having a different spatial arrangement than the input optical signal. A fiber output is held in spaced relation to the output aperture such that fiber cores of the fiber output receive the plurality of output optical signals.

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.
