Deterministic Control of Atom-Cavity Coupling — •B. Weber, S. Nußmann, M. Hijlkema, F. Rohde, A. Kuhn, and G. Rempe — Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Str. 1, 85741 Garching

We present an experimental setup to achieve deterministic control of the coupling of a single Rb atom to a high-finesse optical cavity. By means of an optical dipole force trap made of a single running-wave laser beam we transport cold atoms from a magneto-optical trap over a distance of 14 mm into the mode volume of the cavity. With the cavity used as an atom detector, we observe the arrival of the atom cloud as well as characteristic single-atom transit signals in the transmitted intensity. Trapping the atoms by means of a standing-wave laser field inside the cavity will allow us to generate long streams of single photons for quantum information processing.
