Millikelvin System for Cold Atom Superconductor Hybrid Quantum Devices — •Florian Jessen, Martin Knufinke, Petra Vergien, Malte Reinschmidt, Helge Hattermann, Simon Bernon, Simon Bell, Daniel Cano, Dieter Kölle, Reinhold Kleiner, and József Fortágh — Center for Collective Quantum Phenomena, Eberhard Karls Universität Tübingen, Auf der Morgenstelle 14, 72076 Tübingen

Hybrid quantum systems based on ultracold atoms and superconducting devices are promising candidates for fundamental physics as well as quantum information especially superconducting quantum circuits require millikelvin temperatures for their operation and sufficiently long coherence time. Towards realisation of the cold atom/superconductor quantum interface we installed cold atoms setup into a delution refrigerator reaching a base temperature of 50mK. We report on the operation of this system.
