摘要
A single-photon source scheme based on entangled photon pairs from parametric down conversion is proposed, by means of which the single-photon quality is greatly improved, i.e. the multi-photon-pulse probability is reduced 100 times compared with that of an ordinary attenuated weak light source. The optical set-up and data acquisition are explained in detail. Experimental results show the good potential of this system for practical applications.
