Entanglement generation on the strontium optical clock transition in tweezer-defined 2d arrays

ORAL

Abstract

Entanglement generation in large arrays of neutral atoms, combined with high fidelity single particle control and detection, is a critical resource for exploration of quantum many body physics, quantum metrology, and quantum information processing. We trap bosonic strontium in a hybrid apparatus which combines the high imaging resolution, scalability, and tunneling dynamics of quantum gas microscopes with the rapid and programmable low-entropy state preparation afforded by optical tweezers. Recently, we have added the ability to drive directly from the clock state (5s5p3P0) to a Rydberg state (5sns3S1) at high Rabi frequency. We report on the resulting generation of entanglement on the optical clock transition using both detuned and adiabatically resonant Rydberg pulses, and we discuss the implications for a resulting quantum speed up in optical frequency metrology. From a many body physics perspective, this directly implements a transverse field Ising model, and we draw connections between the continuous nonlinear evolution under this model with the generation of spin squeezed and GHZ states relevant to quantum metrology and quantum information processing.
