Distinct statistical properties of quantum two-photon backscattering
10:12 am – 10:24 amInterference between multiple waves in scattering from disordered structures results in the formation of granular patterns known as speckle patterns for both classical and nonclassical excitations. Here, we present an in-depth examination of the single- and two-photon statistics of multiple-scattered biphoton states with different quantum and classical correlations. The studies are conducted for finite disordered structures through a scalar numerical analysis without imposing any statistical assumption on the scattering events. Relevant parameters including the entanglement dimensionality of the excitation and angular arrangement of jointly measurable photon pairs, are studied. Our study presents the essence of fundamentally distinct statistical properties of multiply scattered two-photon states in connection with classical and nonclassical correlations and enables a better understanding of quantum light scattering statistics.
