We have produced a Bose-Einstein condensate (BEC) on an atom
chip using only superconducting wires in a cryogenic environment. We observe the onset of
condensation for 1
104 atoms at a temperature of 100 nK. This result opens
the way for studies of atom losses and decoherence in a BEC interacting with a
superconducting surface. Studies of dipole-blockade with long-lived Rydberg atoms in a small and dense atomic
sample are underway.
