Ultracold dipolar molecules, with their rich internal structure, provide an intriguing platform that gives access to the quantum simulation of many-body physics, state-controlled chemistry, and quantum computing based on molecular qubits. In this poster, we present our progress towards the creation of ground state Na41K bosonic molecules. We prepare ultracold Bose-Bose mixtures of Na-41K via sympathetic cooling of 41K with Na and locate multiple interspecies Feshbach resonances. We then create weakly bound Feshbach molecules that serve as a stepping stone for the creation of Na41K ground state molecules. We present our characterization of Feshbach association efficiency, along with our efforts to find a suitable two-photon pathway down to the absolute ground state.
