Continuous-variable quantum teleportation through lossy channels
A. V. Chizhov, L. Knöll, D. -G. Welsch
The ultimate limits of continuous-variable single-mode quantum teleportation due to absorption are studied, with special emphasis on (quasi-)monochromatic optical fields propagatin…
Entanglement degradation in continuous-variable quantum teleportation
Dirk-Gunnar Welsch, Stefan Scheel, Aleksej V. Chizhov
The influence of losses in the transmission of continuous-variable entangled light through linear devices such as optical fibers is studied, with special emphasis on Gaussian state…
Propagation of entangled light pulses through dispersive and absorbing channels
A. V. Chizhov, E. Schmidt, L. Knoll +1
The modification of initially entangled light pulses passing through dispersive and absorbing four-port devices is studied, using recently obtained results on quantum state transfo…
Quantum state transformation by dispersive and absorbing four-port devices
L. Knoell, S. Scheel, E. Schmidt +1
The recently derived input-output relations for the radiation field at a dispersive and absorbing four-port device [T. Gruner and D.-G. Welsch, Phys. Rev. A 54, 1661 (1996)] are us…
