Optical tweezer array of rovibronic ground-state NaCs molecules

The ability to trap and control molecules at the individual particle level is at the heart of many proposals that could utilize their rich internal states and long-range dipole-dipole interactions. In our approach to gaining full quantum state control of molecules, we assemble single molecules from single atoms trapped in optical tweezers [Zhang et al., PRL. 124, 253401 (2020); Cairncross, Zhang et al. PRL (in press)]. While we focused on building exactly one molecule from two atoms previously, in this talk, I will discuss our current progress in expanding the molecule assembly process to arrays of molecules, from which we may begin entangling such molecules for many quantum science applications.
