Abstract: 

The long-range interactions from the large electric dipole moment of ultracold molecules make them exciting candidates for both simulating many-body physics, and as a qubit for quantum computation. I will present results of the deterministic assembly of a single molecule from two ultracold atoms using optical tweezers.  A single Na and Cs atom are individually trapped and cooled in reconfigurable optical tweezers, and then merged together and photoassociated into an ultracold molecule.
