  Strongly interacting atom-cavity systems within a network with many nodes
constitute a possible realization for a quantum internet which allows for
quantum communication and computation on the same platform. To implement such
large-scale quantum networks, nanophotonic resonators are promising candidates
because they can be scalably fabricated and interconnected with waveguides and
optical fibers. By integrating arrays of ring resonators into a vapor cell we
show that thermal rubidium atoms above room temperature can be coupled to
photonic cavities as building blocks for chip-scale hybrid circuits. Although
strong coupling is not yet achieved in this first realization, our approach
provides a key step towards miniaturization and scalability of atom-cavity
systems.
