Do you know that most quantum sources operate today at low-temperature?

Long-distance secured quantum communications will use single-photons exchanged through optical fibers. To render single-photon sources easily exploitable, CRHEA, MajuLab and NTU have introduced point defects in GaN that deliver single-photons at room-temperature and at telecommunication wavelengths compatible with the national French and Singaporean quantum networks.
