Single atoms trapped at the centre of optical cavities are highly isolated and fully controllable systems that feature a strong light-matter interaction, making them an ideal platform for quantum networking applications.  The optical cavity allows for a reliable reversible mapping between single atoms and single photons, making it possible to store, process and distribute quantum information over the network. Neutral-atom cavity experiments, however, have been so far limited to one or two individually controlled atomic qubits. Here, by employing reconfigurable optical tweezers, we realise one and two-dimensional ordered arrays of up to six cavity-coupled atoms. Furthermore, we demonstrate a single-site addressing beam to selectively excite individual atoms and generate atom-photon entanglement (APE) using vacuum Stimulated Raman Adiabatic Passages (vSTIRAP). By implementing a multiplexing scheme, we demonstrate a generation-to-detection atom-photon entanglement efficiency of 90%.
