Three-dimensional quantization of the electromagnetic field in dispersive and absorbing inhomogeneous dielectrics
Ho Trung Dung, L. Knoell, D. -G. Welsch
A quantization scheme for the phenomenological Maxwell theory of the full electromagnetic field in an inhomogeneous three-dimensional, dispersive and absorbing dielectric medium is…
Homodyne measurement of exponential phase moments
M. Dakna, T. Opatrny, D. G. Welsch
It is shown that the exponential moments of the canonical phase can be directly sampled from the data recorded in balanced homodyne detection. Analytical expressions for the sampli…
Number phase uncertainty relations: verification by homodyning
T. Opatrny, M. Dakna, D. -G. Welsch
It is shown that fundamental uncertainty relations between photon number and canonical phase of a single-mode optical field can be verified by means of balanced homodyne measuremen…
Photon-added state preparation via conditional measurement on a beam splitter
M. Dakna, L. Knoll, D. -G. Welsch
We show that conditional output measurement on a beam splitter may be used to produce photon-added states for a large class of signal-mode quantum states, such as thermal states, c…
Least-squares inversion for density-matrix reconstruction
T. Opatrny, D. -G. Welsch, W. Vogel
We propose a method for reconstruction of the density matrix from measurable time-dependent (probability) distributions of physical quantities. The applicability of the method base…
