Beschreibung
Zusammenfassung:	A quantum memory device and methods for storage and retrieval of a qubit from the quantum memory device are described. The quantum memory device includes a first optical component to convert an input qubit encoded in an arbitrary polarization state of a photon into a spatial qubit propagating in a pair of parallel optical rails, an atomic vapor memory to store the spatial qubit in an atomic vapor, and a second optical component to combine the spatial qubit, when retrieved from the atomic vapor memory, into an output qubit encoded in an arbitrary polarization state of a photon.
