Continious Variable (CV) Entanglement Formulation for Bipartite Quantum System

Abstract

We analyze density operator, Q function, photon statistics, quadrature squeezing, and Cv entanglement that holds true for a pair of superposed two-mode photon system. We also present a slightly modified definition of entanglement and squeezing for a pair of super- posed two-mode system and new definition for degree of entanglement. In order to carry out our analysis, we consider a quantum system with Gaussian variables with zero mean. It is found that maximum degree of entanglement as well as squeezing occurs at steady-state and threshold.
