| Abstract(in English) | For an efficient quantum key distribution, highly pure single-photon generation from a semiconductor quantum dot was demonstrated at wavelength in which a Si-avalanche photodiode single-photon detector has high quantum efficiency. Single photon in number state associated with single exciton transition was confirmed by photon correlation measurements. Excitation power dependence of photon coincidence counts revealed that involvement of multi-exciton states affected the photon emission property and gave rise to degradation of purity. Photon pair generation due to biexciton-exciton cascaded transition was also demonstrated. |
