Paper Abstract

Single photon counting module (SPCM) has been widely used in quantum information processing (QIP) to investigate the novel quantum-mechanical phenomena. We analysis the effect of SPCMs on photon statistics of light fields by mean of Hanbury Brown and Twiss (HBT) configuration. It shows that the measured second-order degree of coherence g(2) and Mandel Q factor for different states are strongly corrected. The total efficiency and background are taken into account. The agreement between experiment based on the coherent as well as thermal fields and the theory is quite good.
