Rydberg atom arrays are a promising platform for quantum information and quantum computation. However, they lack a photonic link, such as an optical cavity, which could be used for fast non-destructive readout for error correction or for remote entanglement of distant arrays, thus extending the computational capabilities of the platform. The integration between an optical cavity and Rydberg atoms is challenging due to their large polarizability: noise in the electric field generated by surface charges on a cavity can severely limit coherence times. Here we use a nanoscale photonic crystal cavity attached to a fiber. Due to its small size, the nanocavity is a promising candidate for such a photonic interface for Rydberg atom arrays. We characterize the coherence of single- and two-atom Rydberg states near the PCC suggesting a pathway towards their successful integration.
