Abstract

We determine the Von Neumann entropy and the mutual information of an arbitrary bipartite Gaussian state. A comparison between mutual information and entanglement of formation for symmetric states is considered, remarking the crucial role of the symplectic eigenvalues in qualifying and quantifying correlations.
