Generation of entangled atom-photon states via reflection off an optical cavity — •Bastian Hacker, Andreas Reiserer, Norbert Kalb, Mahmood Sabooni, Stephan Ritter, and Gerhard Rempe — Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Straße 1, 85748 Garching

Entanglement is a key resource for quantum communication and quantum computing. We demonstrate a novel approach to generate entangled states between a single trapped atom and an impinging optical photon via an atom-photon quantum gate, which is based on reflection of a photon from a high-finesse optical cavity containing the single atom. In the strong coupling regime, entanglement between the spin of the atom and the polarization of the photon can be generated. The potential for the generation of entangled states between the atom and more than one photon and prospects to even mediate photon-photon interactions will be discussed.
