Abstract
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 5K is demonstrated in a Hong-Ou-Mandel interference experiment. Prospects for realizing efficient quantum network nodes using SiV centers are discussed.

While NV centers can be used as excellent quantum registers, the current efforts to scale up these proof-of-concept experiments are limited by the small probability of coherent photon emission from NV centers and their spectral stability [6,7]
