Neutral atoms trapped in optical lattices allow for precise measurements, quantum simulation, and quantum computation. Here, we demonstrate the essential building blocks for a quantum simulator: state-dependent trapping, large, homogeneous optical lattices, single-atom resolved fluorescence imaging, and high-resolution optical spectroscopy. We present the first coherent excitation of the ultranarrow 1S0-3P2 magnetic quadrupole transition in 88Sr. Building on this work, we demonstrate high-fidelity Rabi oscillations between the 3P0 and 3P2 state. The developed spectroscopy methods enable us to perform quantum simulations on strongly coupled light-matter interfaces.
