Integration of microoptics on atom chips — •Kai Wicker, Marco Wilzbach, Dennis Heine, Björn Hessmo, and Jörg Schmiedmayer — Physikalisches Institut der Universität Heidelberg, Philosophenweg 12, 69120 Heidelberg, Germany

To develop the atom chip towards a universal tool for quantum information processing, we explore the possibility of integrating micro-optical components for the preparation, manipulation, and detection of atomic qubit states. As a first step we are working on the implementation of an integrated single atom detector based on an optical fibre cavity. First fibre cavities have been realized and tested in our labs. At the moment we are exploring several new cavity designs allowing for higher detection efficiency. We will describe our setup, show first measurements with these designs and give first experimental results.
