Atomic entanglement near a realistic microsphere
Ho Trung Dung, S Scheel, D-G Welsch +1
We study a scheme for entangling two-level atoms located close to the surface of a dielectric microsphere. The effect is based on medium-assisted spontaneous decay, rigorously taki…
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…
Entanglement generation and degradation by passive optical devices
Stefan Scheel, Dirk-Gunnar Welsch
The influence of losses in the interferometric generation and the transmission of continuous-variable entangled light is studied, with special emphasis on Gaussian states. Based on…
3D input-output relations of quantized light at dispersing and absorbing multilayer dielectric plates
Stefan Scheel, Dirk-Gunnar Welsch
The theory developed by Gruner and Welsch [Phys. Rev. A 54, 1661 (1996)] for calculating the 1D input-output relations of the quantized electromagnetic field at dispersing and abso…
