Atom Interferometry on Atom Chips - A Novel Approach Towards Precision Inertial Navigation System - PINS
Abstract
We have proposed and experimentally demonstrated a new technique for creating spin squeezed states of distant atoms by their common interaction with a driven resonator mode. Using this technique we achieve the largest spin squeezing to date, 5.6dB of improvement in signal-to-noise ratio over the standard quantum limit. We have demonstrated a squeezed atomic clock that reaches a given precision a factor of 2.8 faster than a clock operating at the standard quantum limit. Furthermore we have experimentally demonstrated that an atom-optics kicked rotor can remove the interference signal due to chosen interferometer paths in a four-pulse atom interferometer. The interferometer output is dominated by two degenerate spatial loops: the nonreciprocal "trapezoid" loop and the reciprocal "figure-8" loop. By applying the kicked rotor sequence at a particular time we suppressed the contribution of the "trapezoid" loop to the interferometer signal while preserving the contribution due to the "figure-8" loop. We have also demonstrated a robust "macro-chip" as a guide for stationary interferometer and investigated the properties of such interferometer.
