Coherent Shaping of Photons using Electromagnetically Induced Transparency — •Andreas Neuzner, Eden Figueroa, and Gerhard Rempe — Max-Planck-Institute of Quantum Optics, Hans-Kopfermann-Str. 1, 85748 Garching

Over the last decade the effect of light-storage using electromagnetically induced transparency (EIT) has received extensive attention as a potential candidate for the realization of optical quantum memories. Towards this goal several milestones have been reached, for example, the storage and retrieval of single photons [1]. A key addition to these developments towards the implementation of future hybrid quantum networks is the full control over the temporal shape of the retrieved photon. We have set up an EIT-experiment based on a ⁸⁷Rb vapour cell, capable of storing weak classical pulses. In addition, a protocol to arbitrarily shape the envelope of the read-out light has been implemented [2]. We will also discuss the possibilities of this setup as a storage device for single photons generated from a cavity QED based source [3].
