Hybrid Quantum Systems of Ultracold Atoms and Superconductors — •Helge Hattermann, Lörinc Sárkány, Patrizia Weiss, Simon Bernon, Daniel Bothner, Benedikt Ferdinand, Matthias Rudolph, 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 present recent experimental progress towards coupling between cold atoms and superconducting quantum circuits. We show that atomic ensembles can be trapped magnetically in a superconducting coplanar waveguide resonator, where long-lived atomic superposition states with coherence times on the order of seconds can be prepared. The next research goal will be the resonant coupling between trapped atoms and the superconducting microwave cavity.

Furthermore, we demonstrate the sensitivity of ultracold atomic ensembles to quantized flux in a superconducting ring.
