Entanglement of formation for an arbitrary two-mode Gaussian state

Quantum Physics 2009-11-13 v3

Abstract

We write the optimal pure-state decomposition of any two-mode Gaussian state and show that its entanglement of formation coincides with the Gaussian one. This enables us to develop an insightful approach of evaluating the exact entanglement of formation. Its additivity is finally proven.
