Quantum-state extraction from high-Q cavities
M. Khanbekyan, L. Knöll, A. A. Semenov +2
The problem of extraction of a single-mode quantum state from a high-Q cavity is studied for the case in which the time of preparation of the quantum state of the cavity mode is sh…
Electromagnetic-field quantization and spontaneous decay in left-handed media
Ho Trung Dung, Stefan Yoshi Buhmann, Ludwig Knöll +2
We present a quantization scheme for the electromagnetic field interacting with atomic systems in the presence of dispersing and absorbing magnetodielectric media, including left-h…
Input-output relations at dispersing and absorbing planar multilayers for the quantized electromagnetic field containing evanescent components
Mikayel Khanbekyan, Ludwig Knöll, Dirk-Gunnar Welsch
By using the Green-function concept of quantization of the electromagnetic field in dispersing and absorbing media, the quantized field in the presence of a dispersing and absorbin…
Linear optics substituting scheme for multi-mode operations
J. Clausen, L. Knoell, D. -G. Welsch
We propose a scheme allowing a conditional implementation of suitably truncated general single- or multi-mode operators acting on states of traveling optical signal modes. The sche…
The van der Waals energy of atomic systems near absorbing and dispersing bodies
Stefan Yoshi Buhmann, Ho Trung Dung, Dirk-Gunnar Welsch
Within the frame of macroscopic quantum electrodynamics in causal media, the van der Waals interaction between an atomic system and an arbitrary arrangement of dispersing and absor…
Entanglement purification of multi-mode quantum states
J Clausen, L Knoell, D-G Welsch
An iterative random procedure is considered allowing an entanglement purification of a class of multi-mode quantum states. In certain cases, a complete purification may be achieved…
