Simple direct measurement of nonclassical joint signal-idler photon-number statistics and correlation area of twin photon beams
arXiv:0708.2241 · doi:10.1088/1464-4266/7/12/020
Abstract
The measurement of joint signal-idler photon-number distribution of a field obtained from spontaneous parametric downconversion using an intensified CCD camera is presented. It is shown that a classicality criterion is violated directly by the measured data. Characteristic dimensions of the area of correlation are determined in the same experimental setup.
