  Single photon emitters (SPEs) play an important role in a number of quantum
information tasks such as quantum key distributions. In these protocols,
telecom wavelength photons are desired due to their low transmission loss in
optical fibers. In this paper, we present a study of bright single-photon
emitters in cubic silicon carbide (3C-SiC) emitting in the telecom range. We
find that these emitters are photostable and bright at room temperature with a
count rate of ~ MHz. Together with the fact that SiC is a growth and
fabrication-friendly material, our result may pave the way for its future
application in quantum communication technology applications.
