Individual addressing of multiple neutral atoms in an optical cavity — •Andreas Neuzner, Matthias Körber, Carolin Hahn, Stephan Ritter und Gerhard Rempe — Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Straße 1, 85748 Garching

Single neutral atoms trapped in a Fabry-Perot-type optical cavity were shown to be a powerful system for the implementation of various quantum-information-processing protocols. This includes the highly efficient creation of single photons and the implementation of an optical quantum memory based on a single ⁸⁷Rb atom. We present recent progress on the addressing of several atoms trapped in a two-dimensional optical lattice within the resonator by means of a high-numerical-aperture objective. The addressing capability is used to quasi-deterministically load predetermined patterns of atoms and to control the interaction of individual atoms with the resonator mode. Progress towards the realization of a multi-qubit memory for a quantum repeater node will be presented.
