We report on our recent progress constructing a novel experimental platform for ytterbium atoms. Our approach combines optical lattices and optical tweezers, providing a versatile, robust and scalable environment for both analog and digital quantum simulation. A central ingredient of our implementation are optical potentials at the magic and tune-out wavelengths for the ground and meta-stable clock state of ytterbium. Leveraging high-resolution optical clock spectroscopy, we present preliminary results from our efforts to experimentally determine two new magic wavelengths and the ground-state tune-out wavelength near the narrow cooling transition at 556nm. Furthermore, we demonstrate loading, cooling and imaging of individual atoms in our tweezer array. Possible avenues of research include the simulation of lattice gauge theories and the implementation of quantum computing schemes by means of collisional gates.
