In atom chip experiments, cold alkali atoms can be trapped at distances as close as a few tens of micrometers from a conducting surface. The dissipation in the surface leads to a fluctuating magnetic field, which can induce Zeeman transitions towards untrapped states. The lifetime of the cloud then decreases as the cloud is brought closer to the surface. One promising solution to circumvent this problem would be to use a chip made of superconducting microwires instead of normal conductors.In this thesis, we have obtained the first Bose-Einstein condensate on a superconducting atom chip. Approximately 10.000 condensed atoms are trapped 50 micrometers away from the superconducting surface, at a temperature of 100 nK. These results show the fe...
