Noise limits on Bose-Einstein condensate gyroscope performance

We present a theoretical study of the impact of several noise sources on the sensitivity and performance of an atom-based Sagnac gyroscope. We consider a device that uses Bose condensed atoms that are split by light fields and counter-propagate around a loop produced by magnetic potentials created with an atom chip. In addition to atom shot noise and atom interactions, electrical current shot noise and Johnson noise impose fundamental limits on device performance. Magnetic field fluctuations and vibrations from external sources also introduce noise. We examine how these effects impact the performance of the gyroscope.
