An outstanding challenge in quantum optics is to coherently couple a solid-state spin to single photons. Such a single-quantum light-matter interface forms a critical resource for long distance quantum cryptography and networked quantum computation architectures. A particularly promising approach exploits a defect in diamond – the nitrogen-vacancy (NV) center – whose optical transitions can mediate interactions between photons and long-lived electronic and nuclear spins. By placing the defect inside an optical resonator, these interactions can be strongly enhanced, in principle even into the quantum-coherent regime.

量子光学中一个突出的挑战是相干耦合固态自旋到单光子。这样的单量子光物质界面形成了长距离量子密码和网络量子计算架构的关键资源。一种特别有前途的方法利用了金刚石中的缺陷-氮空位（NV）中心-其光学跃迁可以介导光子与长寿命电子和核自旋之间的相互作用。通过将缺陷放置在光学谐振器内，这些相互作用可以被强烈增强，原则上甚至进入量子相干状态。
