Description
Arrays of ultracold polar molecules exhibit long-range, long-lived dipole-dipole interactions that can be harnessed for the quantum simulation of matter, quantum computation, and precision measurements. Crucial to many of these proposals is the ability to produce adjacent pairs of molecules whose quantum states we can individually control. To that end, we detect vacancies in arrays of individually trapped Na and Cs atoms and use acousto-optic deflectors to rearrange the atoms into a vacant free-region. Each pair of Na and Cs is Raman sideband cooled and merged into the same trap, which we then magnetoassociate at a Feshbach resonance and transfer to the NaCs rovibronic ground state using a two-photon STIRAP sequence. Additionally, we performed spectroscopy of the NaCs $c^3\Sigma$ potential. We identified a 15 MHz wide intermediate state for our STIRAP transfer that is more efficient than a 120 MHz wide state used in our prior work. This efficient production of fully quantum-state-controlled polar molecules in optical tweezers will provide new opportunities for dipole-dipole interaction mediated quantum computation and quantum simulation applications.
