Abstract
We consider the bipartite state of a two-photon polarization system and obtain the exact analytical expression for the von Neumann entropy in the particular case of polarization when the entropy depends on only five parameters rather than the full fifteen parameters. We investigate and graphically illustrate the dependence of the entropy on these five parameters, in particular, the existence of exotic to nonexotic statetransitions in single- and two-photon correlations.
