AbstractEfficient interfaces between photons and memory qubits constitute fundamental build- ing blocks for quantum networking and large-scale quantum information processing. Our approach utilizes a photonic crystal cavity to realize such optical interfaces for atoms in optical tweezers. With this platform, we observe strong coupling between two atoms mediated by the cavity. Combining this observation with coherent manipulation and non-destructive measurements, we implement a protocol for generating Bell pairs that remain entangled when transported away from the cavity structure. These results present prospects for building integrated optical interconnects for neutral atom quan- tum information processors, adding capabilities such as rapid non-destructive readout and flexible connectivity to the rapidly-growing platform.
