Description
Quantum networks rely on efficient light–matter interfaces to connect optical photons with long-lived quantum memories. In this talk, I will present two complementary approaches using neutral atoms coupled to optical cavities. The first employs ordered arrays of individually trapped atoms in a hybrid tweezer–lattice architecture, enabling precise control, low decoherence, and highly efficient atom–photon entanglement generation with multiplexing capabilities. The second approach uses a cold atom cloud in a low-finesse cavity, where collective spin-wave excitations couple strongly to the cavity field, leading to enhanced retrieval efficiencies and clear signatures of vacuum-Rabi splitting. Together, these results demonstrate distinct pathways toward scalable and versatile quantum network nodes.
