Ultracold polar molecules are able to interact at long-range via electric dipole-dipole interactions, which can be used to generate entanglement between distant molecules by coherently coupling their rotational quantum states. This capability makes such molecules an attractive platform for simulation of quantum matter and for quantum computing. We present our recent work on coherent control of the rotational and hyperfine degrees of freedom of a 1D array of ultracold NaCs molecules in optical tweezers. We perform coherent microwave spectroscopy of the molecules in the rotational ground and first excited state manifold. We further demonstrate site-selective excitation of individual molecules using a global microwave pulse by varying the light-shift induced by the tweezer beams at different sites, which allows us to arbitrarily position rotational excitations in our molecule array. Finally, we present our progress towards engineering coherent transfer of rotational excitations between sites via dipole-dipole coupling.
