Mapping quantum states of light onto long-lived matter excitations is considered an important step in the realization of optical quantum communication and computation architectures [1]. In quantum communication the manifold approaches to this task are subsumed under the topic of quantum memories [2]. Multiplexing of these memories helps to achieve higher communication rates per link and is especially important on links that exhibit high loss [3].
We present a multi-rail EIT memory [4] within a single Cs vapor cell at room temperature. By deflecting the co-propagating signal and control beams, multiple non-interacting volumes within a single Cs vapor cell are addressed. Storing to and retrieving from randomly selected rails is then demonstrated by changing the AOM driving frequency.
