Quantifying the Entanglement of Gaussian States — •Geza Giedke1,2, Michael Wolf3,1, Reinhard F. Werner3, and J. Ignacio Cirac1 — 1Max-Planck-Institut für Quantenoptik, Garching — 24. Physikalisches Institut, Universität Stuttgart — 3Institut für Mathematische Physik, TU Braunschweig
We introduce an entanglement measure for general Gaussian states that can be easily computed and is non-zero for entangled states with positive partial transpose. We calculate the entanglement of formation for two-mode Gaussian states. We relate these measures to concrete quantum information tasks.
