Continuous-variable Werner state: separability, nonlocality, squeezing and teleportation
Ladislav Mista, Radim Filip, Jaromir Fiurasek
We investigate the separability, nonlocality and squeezing of continuous-variable analogue of the Werner state: a mixture of pure two-mode squeezed vacuum state with local thermal…
Bell-inequality violation with "thermal" radiation
Radim Filip, Miloslav Dusek, Jaromir Fiurasek +1
The model of a quantum-optical device for a conditional preparation of entangled states from input mixed states is presented. It is demonstrated that even thermal or pseudo-thermal…
Continuously induced coherence without induced emission
J. Rehacek, L. Mista, J. Fiurasek +1
The coherence properties of two downconversion processes continuously coupled via idler beams are analyzed. We find that the amount of which-way information about a signal photon c…
