Abstract

A light–matter interface: solid progress To realize scalable quantum information networks in the near future, it will be important to develop techniques for storage and retrieval of light at the single photon level. Quantum interfaces between light and matter have been demonstrated before, but mainly with atomic gases, necessitating sophisticated schemes to trap the atoms. de Riedmatten et al. demonstrate a potentially more practical approach; coherent and reversible mapping of a light field with less than one photon per pulse onto an ensemble of about 107 atoms naturally trapped in a solid-state medium. The state of the light is mapped onto collective atomic excitations on an optical transition and stored for a pre-programmed time up of to one microsecond before being retrieved again. The authors also demonstrate that light can be stored in multiple temporal modes and believe that their multimode solid-state quantum memories are promising alternative to atomic gases.
