Heralded atomic-ensemble quantum memory for photon polarization states
... conceptually simplest quantum memory is a single two-level atom. Coherent mapping between a photon and the atom that is acting as a quantum memory requires the atom to appear opaque to the photon. This can be achieved by focusing the photon to a small area containing the atom, and passing it through ...
