The Molecules in Tweezers project is a new experiment at Durham University and is part of QSUM: Quantum Science with Ultracold Molecules. The aim of the project is to assemble an interacting quantum system one molecule at a time. By trapping individual Rb and Cs atoms in tightly focussed optical tweezer traps, we will assemble single molecules by merging the microtraps and associating the atoms, and we will subsequently transfer the molecules to their ground rovibrational state. This scheme will be scaled to several molecules, giving us a deterministically prepared array of ultracold molecules.
