I'd never heard that term either, but it sounds like this is what they're referring to: > "We were the first to isolate single-photon emitters in the most widespread material of the microelectronics industry: silicon," Dr.éau said. "Furthermore, these artificial atoms based on single fluorescent point defects have the great advantage of emitting single-photons directly at telecom wavelength, which is convenient for long-distance propagation inside optical fibers."
