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…
Interaction of the quantized electromagnetic field with atoms in the presence of dispersing and absorbing dielectric bodies
Stefan Scheel, Dirk-Gunnar Welsch
A general theory of the interaction of the quantized electromagnetic field with atoms in the presence of dispersing and absorbing dielectric bodies of given Kramers--Kronig consist…
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…
Entanglement transformation at absorbing and amplifying four-port devices
Stefan Scheel, Ludwig Knoll, Tomas Opatrny +1
Dielectric four-port devices play an important role in optical quantum information processing. Since for causality reasons the permittivity is a complex function of frequency, diel…
