具有多个节点的网络中强相互作用的原子-腔系统构成了量子互联网的一种可能实现，它允许在同一平台上进行量子通信和计算。为了实现如此大规模的量子网络，纳米光子谐振器是很有希望的候选者，因为它们可以被可扩展地制造并与波导和光纤互连。通过将环形谐振器阵列集成到蒸汽池中，我们证明了室温以上的热Rb原子可以耦合到光子腔中，作为芯片级混合电路的构建块。虽然在第一个实现中还没有实现强耦合，但我们的方法为原子-腔系统的小型化和可扩展性提供了关键的一步。
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.
