Abstract
A number of techniques exist to use an ensemble of atoms as a quantum memory for light. Many of these propose to use backward retrieval as a way to improve the storage and recall e ciency. We report on a demonstration of an o -resonant Raman memory that uses backward retrieval to achieve an e ciency of 65 ± 6% at a storage time of one pulse duration. The memory has a characteristic decay time of 60 µs, corresponding to a delay-bandwidth product of 160.
