A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglement, fast and high-efficiency detection and unpredictable measurement

On the equivalence of the Langevin and auxiliary field quantization methods for absorbing dielectrics

Autor: Tip, A., Knoll, L., Scheel, S., Welsch, D. -G.

Recently two methods have been developed for the quantization of the electromagnetic field in general dispersing and absorbing linear dielectrics. The first is based upon the introduction of a quantum Langevin current in Maxwell's equations [T. Grune

Conditional quantum state engineering in repeated 2-photon down conversion

Autor: Clausen, J., Hansen, H., Knoll, L., Mlynek, J., Welsch, D. -G.

Publikováno v: Appl. Phys. B 72, 43 (2001)

The U(1,1) and U(2) transformations realized by three-mode interaction in the respective parametric approximations are studied in conditional measurement, and the corresponding non-unitary transformation operators are derived. As an application, the

Measuring quantum state overlaps of traveling optical fields

Autor: Clausen, J., Dakna, M., Knoll, L., Welsch, D. -G.

Publikováno v: Opt. Commun. 179, 189 (2000)

We propose a detection scheme for measuring the overlap of the quantum state of a weakly excited traveling-field mode with a desired reference quantum state, by successive mixing the signal mode with modes prepared in coherent states and performing p

Conditional quantum-state transformation at a beam splitter

Autor: Clausen, J., Dakna, M., Knoll, L., Welsch, D. -G.

Using conditional measurement on a beam splitter, we study the transformation of the quantum state of the signal mode within the concept of two-port non-unitary transformation. Allowing for arbitrary quantum states of both the input reference mode an
