Integrating strong-coupling cavity QED with atomic tweezer arrays
ORAL · Invited
Abstract
Strongly coupling an atomic optical emitter to an optical resonator, the setting for cavity quantum electrodynamics (QED), allows for exquisite control over matter-light interactions. Optical tweezer arrays, loaded deterministically with a single atom in each tweezer, allow for exquisite control over ultracold atoms and enable a bottom-up approach to constructing many-body quantum systems. I will present an experimental setup that integrates these two approaches to engineering, controlling, and measuring quantum systems made up of atoms and light. I will discuss two scientific pursuits. First, we employ cavity QED to bring new capabilities to the control and measurement of atom tweezer arrays. Specifically, we demonstrate coherent and fast mid-circuit measurement of individual tweezers within an array. Second, we employ tweezer arrays to bring new capabilities to the study of cavity QED. Specifically, we demonstrate control over collective light-atom interactions, observing collective enhancement of light emission from a microscopically constructed atomic ensemble. I will conclude by discussing how our system should allow us to explore various representations of the Dicke model to study mesoscopic effects and a rich set of symmetry classes.
