Electro-optic quantum memory for light using two-level atoms

Hetet, Gabriel; Longdell, Jevon; Alexander, Annabel; Lam, Ping Koy; Sellars, Matthew


We present a simple quantum memory scheme that allows for the storage of a light field in an ensemble of two-level atoms. The technique is analogous to the NMR gradient echo for which the imprinting and recalling of the input field are performed by controlling a linearly varying broadening. Our protocol is perfectly efficient in the limit of high optical depths and the output pulse is emitted in the forward direction. We provide a numerical analysis of the protocol together with an experiment...[Show more]
