Continuous-variable Werner state: Separability, nonlocality, squeezing, and teleportation
Ladislav Mišta, Radim Filip, Jaromı́r Fiurášek · Physical Review A · 2002
We investigate the separability, nonlocality, and squeezing of the continuous-variable analog of the Werner state: a mixture of a pure two-mode squeezed vacuum state with local thermal radiations. Utilizing this Werner state, coherent-state teleportation in the Braunstein-Kimble setup is discussed.
