    "abstract": "We have trapped rubidium atoms in the magnetic field produced by a\nsuperconducting atom chip operated at liquid Helium temperatures. Up to\n$8.2\\cdot 10^5$ atoms are held in a Ioffe-Pritchard trap at a distance of 440\n$\\mu$m from the chip surface, with a temperature of 40 $\\mu$K. The trap\nlifetime reaches 115 s at low atomic densities. These results open the way to\nthe exploration of atom--surface interactions and coherent atomic transport in\na superconducting environment, whose properties are radically different from\nnormal metals at room temperature.",
