    "abstract": "We report the coherent manipulation of internal states of neutral atoms in a\nmagnetic microchip trap. Coherence lifetimes exceeding 1 s are observed with\natoms at distances of $5-130 \\mu$m from the microchip surface. The coherence\nlifetime in the chip trap is independent of atom-surface distance within our\nmeasurement accuracy, and agrees well with the results of similar measurements\nin macroscopic magnetic traps. Due to the absence of surface-induced\ndecoherence, a miniaturized atomic clock with a relative stability in the\n$10^{-13}$ range can be realized. For applications in quantum information\nprocessing, we propose to use microwave near-fields in the proximity of chip\nwires to create potentials that depend on the internal state of the atoms.",
