Abstract
We have measured the phase shift induced by rotation of an atom interferometer at rates of to earth rates and obtained agreement with the predicted Sagnac phase shift for atomic matter waves. The rotational rms noise of our interferometer was milliearth rates for sec of integration time, within of shot noise. The high sensitivity and agreement of predicted and measured behavior suggest useful future scientific applications of atom interferometers as inertial sensors.
