biostudies-literatureUnknown10(1)Kim METrapped 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.Nature communications1647https://www.ebi.ac.uk/biostudies/studies/S-EPMC6456496biostudies-literatureTrapping single atoms on a nanophotonic circuit with configurable tweezer lattices.PMC6456496Chang THHung CLFields BMChen CAKim MEfalseTrapping single atoms on a nanophotonic circuit with configurable tweezer lattices.Trapped atoms near nanophotonics form an exciting platform for bottom-up synthesis of strongly interacting quantum matter.
