  Trapped atoms near nanophotonics form an exciting platform for bottom-up
synthesis of strongly interacting quantum matter. The ability to induce tunable
long-range atom-atom interactions with photons presents an opportunity to
explore many-body physics and quantum optics. Here we implement a configurable
optical tweezer array over a planar photonic circuit tailored for cold atom
integration and control for trapping and high-fidelity imaging of one or more
atoms in an array directly on a photonic structure. Using an optical conveyor
belt formed by a moving optical lattice within a tweezer potential, we show
that single atoms can be transported from a reservoir into close proximity of a
photonic interface, potentially allowing for the synthesis of a defect-free
atom-nanophotonic hybrid lattice. Our experimental platform can be integrated
with generic planar photonic waveguides and resonators, promising a pathway
towards on-chip many-body quantum optics and applications in quantum
technology.
