Quantum Science with an Optical Tweezer Array of CaF Molecules

Ultracold polar molecules are a promising platform for quantum science due to their rich internal structure and long lived interacting states. These features have been proposed for use in quantum simulation, quantum information processing, and tests of fundamental physics. A crucial requirement in many applications is a high degree of control over internal and sometimes external degrees of freedom. In this poster, we present work on an optical tweezer array of laser-cooled CaF molecules, where all degrees of freedom can be in principle controlled and single site manipulation and readout is possible. Specifically, we report recent work on 1) creating cold and dense samples with a Blue-Detuned MOT (BDM), 2) erasure conversion that significantly improves internal state preparation and is highly relevant to quantum error correction, and 3) ongoing explorations of molecular arrays as a simulation platform for interacting spin 1/2 models.
