Single-photon sources are of paramount importance in quantum communiion, quantum computation, and quantum metrology. In particular, there is great interest in realizing scalable solid-state platforms that can emit triggered photons on demand to achieve scalable nanophotonic networks. We report on a visible-spectrum single-photon emitter in 4H silicon carbide (SiC).

Since the 1997 publiion of "Silicon Carbide - A Review of Fundamental Questions and Appliions to Current Device Technology" edited by Choyke, et al., there has been impressive progress in both the fundamental and developmental aspects of the SiC field. So there is a growing need to update the scientific community on the important events in research and development since then.
Abstract. We present 7.5-13.5 μm UKIRT CGS3 spectra of 32 definite or candidate carbon stars. In addition to the extreme carbon star AFGL 3068, the only carbon star previously known to show the 11-μm silicon carbide (SiC) feature in absorption, we have discovered three further examples of sources that show SiC in net absorption, namely IRAS 02408 + 5458, AFGL 2477 and AFGL 5625.
