Abstract: We built a novel experimental setup for transferring and trapping 87Rb ultracold atoms inside a millikelvin cryogenic environment. The atoms are prepared in a conventional magneto-optical trap and transported via a magnetic conveyor belt into a UHV compatible dilution refrigerator with optical access. We store 5x10^8 atoms in a magnetostatic trap with an unprecedented lifetime of 794 seconds in the vicinity of the millikelvin stage. On the other hand, we established the manufacturing process of superconducting qubits. Our qubit of choice is the transmon qubit, either in a 3D architecture or in its planar Xmon form. Qubit design, simulation, manufacturing and calibration are presented. We proposed several coupling schemes between superconducting qubits and ultracold atoms and also the enhancement of the superconducting qubit coherence, exploiting the atomic-clock technique.
