| Abstract: | Correlated photons are generated in spontaneous parametric down-conversion(SPDC) effect of nonlinear crystal pumped by highly intensity laser.Generation mechanism of correlated photons is explained compendiously by theory of quantum mechanics;interpretation of classical optics is also shown.The theory of detector calibration in quantum efficiency based correlated photons method is demonstrated.Comparing with traditional methods,the advantages of it are pointed out.The latest advances in the field are described here;fundamental ideas,advantages and disadvantages of these methods are analyzed.The next direction of investigation and the method of realization are mentioned.The future of this field is also presented in this paper. |
