Quantum Science with Programmable Tweezer Arrays of CaF Molecules

Polar molecules are a promising platform for quantum science due to their rich internal structure and long-ranged interactions. In this poster, we report our recent work with programmable optical tweezer arrays of laser-cooled CaF molecules. This includes 1) developing mid-sequence error detection methods to mitigate internal molecular state preparation errors and blackbody-induced qubit leakage errors, 2) simulating 1/r^3 XX/XXZ/XYZ quantum spin models in 1D chains, and 3) demonstrating spin squeezing in molecules for the first time.
