Quantifying quantum correlations in noisy Gaussian channels

Abstract

The Gaussian states are essential ingredients in many tasks of quantum information processing.The presence of the noises imposes limitations on achieving these quantum protocols. Therefore, examining the evolution of quantum entanglement and quantum correlations under the coherence of Gaussian states in noisy channels is of paramount importance. In this paper, we propose and analyze a scheme that aims to specify and examine the dynamic evolution of the quantum correlations in twomodes Gaussian states submitted to the influence of the Gaussian thermal environment. We describe
