Cold atoms near superconductors: Towards coherent coupling in a hybrid quantum system — •Helge Hattermann, Lörinc Sárkány, Patrizia Weiss, Daniel Bothner, Matthias Rudolph, Benedikt Ferdinand, Simon Bernon, Reinhold Kleiner, Dieter Koelle, and József Fortágh — CQ Center for Collective Quantum Phenomena and their Applications, Physikalisches Institut Tübingen, Auf der Morgenstelle 14, 72076 Tübingen

We describe an experimental system combining Bose-Einstein condensates and superconducting atom chips at 4.2 K. We demonstrate the coherent state manipulation of atoms at the superconducting chip [1], the generation of noise protected clock states [2] and the design and implementation of superconducting coplanar waveguide cavities. In addition, we present experimental results on the mapping of the flux state in a superconducting ring onto an ensemble of cold atoms.
