Phase Locking a Clock Oscillator to a Coherent Atomic Ensemble

Year: 2015

Type: article

Abstract: Time measurements and navigation rely on atomic interferometers and atomic clocks. A new technique can improve the stability of such clocks by coupling a classical oscillator to an ensemble of atoms in a superposition state using repeated, coherence-preserving measurements.
