Entanglement transformation at dielectric four-port devices
S. Scheel, L. Knoll, T. Opatrny +1
Quantum communication schemes widely use dielectric four-port devices as basic elements for constructing optical quantum channels. Since for causality reasons the permittivity is n…

QED in dispersing and absorbing media
Ludwig Knoll, Stefan Scheel, Dirk-Gunnar Welsch
After giving an outline of the quantization scheme based on the microscopic Hopfield model of a dielectric bulk material, we show how the classical phenomenological Maxwell equatio…

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…
