Hybrid quantum systems based on ultracold atoms and superconductors have been proposed to be used in quantum information processing. In these systems the logical operations will be carried out by the solid state devices, while the cold atomic ensemble can be used as a long lived memory for quantum information.

We report on the construction of a Millikelvin system which meets the requirements of long coherence and strong coupling of superconducting devices and ultracold atomic samples. The atoms are loaded into the MOT via a Zeeman slower and transported close to the superconductiong devices by means of a magnetic conveyor belt within the Millikelvin environment.
