A coherent quantum interface between a neutral atom and a polar molecule
Daniel K. Ruttley, Tom R. Hepworth, Juan M. García-Garrido +4
Arrays of trapped neutral atoms and polar molecules have separately emerged as powerful and complementary platforms for quantum science. Neutral atoms enable fast, programmable int…
