Rydberg-Dressed Ising Interactions for Spin Squeezing*

Rydberg dressing provides a versatile way to create strong coherent interactions between ground-state neutral atoms. These local, optically controlled interactions can theoretically be used to create metrologically useful entanglement, such as spin squeezing in one or more independent atomic ensembles within an array of optical tweezers. Employing one-axis twisting dynamics via single-photon coupling to nP states, we present progress on generating spin squeezing on the clock transition of cesium. Initial observation of spin squeezing with Rydberg dressing will open prospects for optimized squeezing through the addition of a transverse field and implementation of variational algorithms.
