Progress Towards High Efficiency Atom-Photon Interface with Atomic Ensembles

POSTER

Abstract

We describe our progress towards the generation and manipulation of narrow-bandwidth single photons and entangled photon pairs using a room-temperature ensemble of 87Rb atoms. Our method involves the creation of a collective atomic coherence via Raman scattering and projective measurement, followed by the coherent transfer of this atomic coherence to photons using electromagnetically induced transparency (EIT). We describe our current efforts towards developing a high performance system. These include optimization of the atomic level scheme, timing and preparation sequence, and buffer gas pressures.
