Entanglement and Bell's inequalities | We continue the analysis of our previous articles which were devoted to
type-I parametric down conversion, the extension to type-II being
straightforward. We show that entanglement, in the Wigner representation, is
just a correlation that involves both signal and vacuum fluctuations. An
analysis of the detection proc... | 2025-02-18 | 2,025 | continu analysi previou articl devot type parametr convers extens type ii straightforward show entangl wigner represent correl involv signal vacuum fluctuat analysi detect process open way complet descript parametr convers term pure maxwel electromagnet wave |

atomic transitions, and in parametric down conversion by nonlinear optical
crystals, may be represented by positive Wigner densities of the relevant sets
of mode amplitudes. The light fields of all such states are represented as a
