Dynamics of Entanglement In Two-Mode Gaussian Open Quantum Systems

Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 12

Abstract

In the framework of the theory of open systems, we give a description of quantum entanglement for two non-interacting modes embedded in a common thermal environment. We describe the evolution of entanglement in terms of the covariance matrix for the initial Gaussian state. We study the dependence of time evolution of entangled initial squeezed thermal states on the squeezing parameter, the average numbers of thermal photons associated with the two modes, the dissipation parameter and the frequencies in resonant and non-resonant cases. We found that with decreasing the dissipation parameter; the entanglement suppression happens later. By selecting equal frequency for two mode, we can preserve more entanglement of system.
