Heralded atomic-ensemble quantum memory for photon polarization states
... 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 this area many times using mirrors with very low loss [10] ...
