Towards a Spin Squeezed Strontium Optical Lattice Clock with Entanglement Enhanced Performance
ORAL
Abstract
The exquisite sensitivity of high stability optical atomic clocks provides a broad range of potential applications for probing fundamental physics. By avoiding the Dick noise associated with local oscillators, the current state-of-the-art optical atomic clocks has demonstrated operations at the standard quantum limit (SQL) set by quantum projection noise. Quantum engineering of entangled states of the spin ensemble provides an opportunity to reduce the SQL, resulting in improved measurement precision and frequency stability. In this talk, we report on the recent progress of the implementation of spin squeezed states, generated by cavity-mediated quantum nondemolition measurements in a 1D strontium optical lattice clock, with the aim of demonstrating spin-squeezed clock operations below the SQL.
