Separability of Two-Party Gaussian States
arXiv:quant-ph/0107131 · doi:10.1103/PhysRevA.65.054303
Abstract
We investigate the separability properties of quantum two-party Gaussian states in the framework of the operator formalism for the density operator. Such states arise as natural generalizations of the entangled state originally introduced by Einstein, Podolsky, and Rosen. We present explicit forms of separable and nonseparable Gaussian states.
