The Test of Entanglement of Polarization States of a Semi-Classical Optical Parametric Oscillator

Abstract

Abstract:We study the dynamical continuous variable entanglement in a semi-classical Optical parametric oscillator (OPO).The general time evolving photon polarization state vectors arising from exact analytical solutions of Heisenberg's equations of the system are used to obtain the photon polarization Bell state vectors. The reduced density matrices of photon polarization Bell state vectors of the semi-classical OPO produce a greater violation of CHSH Bell's inequality beyond the Cirel'son's inequality.
