Towards Coherent Control of Photons using Electromagnetically Induced Transparency — •Andreas Neuzner, Eden Figueroa und Gerhard Rempe — Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Str. 1, 85748 Garching, Germany

Over the last decade the effect of electromagnetically induced transparency (EIT) and the related effect of storage of light have received extensive attention as a potential candidate for the realization of quantum memories. Towards this goal several milestones have been reached, the most important being the storage of single photons using EIT [1]. Nevertheless, these experiments so far do not offer access to the temporal envelope of the single photon read back from the storage medium.

We envision a device that can store single photons and allows for full control over the temporal shape of the retreived photon. We have set up an EIT-experiment based on a ⁸⁷Rb vapour cell and store weak classical pulses. Currently a protocol to optimize the storage efficiency is being implemented [2] and we explore possibilities to employ this setup as a storage device for single photons generated from a cavity QED based source [3].
