Squeezing-while-rotating of Ytterbium-171 atomic ensemble inside an optical cavity

ORAL

Abstract

Spin squeezing states (SSS) are atomic entangled states that can be used to enhance the atomic precision measurements beyond the standard quantum limit. Existing implementations relying on unitary evolution are primarily based on one-axis twisting induced through coherent cavity feedback. By adding an auxiliary driving Rabi field, our work demonstrates richer dynamics of the collective spin than the squeezing effect, and can be integrated with a recently demonstrated time-reversal protocol to further enhance the metrological gain.
