Abstract Unbreakable secret communication has been a dream from ancient time. It is quantum physics that gives us hope to turn this wizardly dream into reality. The rapid development of quantum cryptography may put an end to the history of eavesdropping. This will be largely due to the advanced techniques related to single quanta, especially infrared single photons. In this paper, we report on our research works on single-photon control for quantum cryptography, ranging from single-photon generation to single-photon detection and their applications.
