Towards simulating quantum spin models in molecular tweezer arrays

Reconfigurable molecular tweezer arrays are a promising platform for quantum science, with recent work demonstrating coherent spin-exchange interactions between pairs of polar molecules. These interactions form the building block for realizing interacting quantum spin models. In this talk, we report advances on controlling programmable tweezer arrays of CaF molecules with relevance to quantum simulation of interacting spin ½ systems in the few and many body limit. Specifically, we report the assembly of 1D chains of molecules with high-fidelity site-resolved internal state preparation. We also discuss progress towards engineering tunable spin-spin interactions, and preliminary measurements of quantum dynamics in our system.
