We present a theoretical method for the efficient analysis of quantum nonlinear dynamics of correlated photons. Since correlated photons can be regarded as a superposition of uncorrelated photons, semiclassical analysis can be applied to this problem. The proposed method is demonstrated for a V-type three-level atom as a nonlinear optical system.

We propose a method to detect photons in superposition of orbital angular momentum (OAM) states using a hologram and path interferometer, and its application to verification of non-classical correlation in photon pairs. The method is free from excess OAM components, and a simple assumption of classical OAM correlation between the two photons removes contributions from excess components from the coincidence curve as well, even when the proposed method is used only on one of the photons.
