We demonstrate that silicon-vacancy (SiV) centers in diamond can be used to efficiently generate coherent optical photons with excellent spectral properties. We show that these features are due to the inversion symmetry associated with SiV centers. The generation of indistinguishable single photons from separated emitters at 5 K is demonstrated in a Hong-Ou-Mandel interference experiment. Prospects for realizing efficient quantum network nodes using SiV centers are discussed.
我们证明，金刚石中的硅空位（SiV）中心可用于高效产生具有优异光谱特性的相干光学光子。我们表明，这些特性归因于与SiV中心相关的反演对称性。在Hong-Ou-Mandel干涉实验中展示了在5K温度下从分离的发射器产生不可区分的单光子。还讨论了使用SiV中心实现高效量子网络节点的前景。
