A Reconfigurable Optical Tweezer Array of CaF Molecules: Progress towards Full Quantum Control

In this poster, we report on progress towards fully controlling laser-cooled CaF molecules in an optical tweezer array. Specifically, we present work on initializing the internal state and spatial configuration of the molecules. With relevance to simulating interacting quantum systems and quantum information processing, we also report on observing coherent interactions between individual molecules, and the on-demand entanglement of molecules into Bell pairs. Looking ahead towards using molecular tweezer arrays as a competitive platform for quantum science, we discuss factors that limit the achieved state preparation and entanglement fidelities, and the pathways towards higher fidelities.
