Quantum Optics

3rd edition of the text book by
Werner Vogel and Dirk-Gunnar Welsch

Research Topics


Quantum effects of radiation fields are studied. Observable nonclassicality conditions are derived and related to measurements.


The characterization and detection of entanglement is studied. New algebraic methods are derived and applied.

Detection of light

Measurement schemes are proposed and rigorously analyzed. Sampling, errors, and imperfections are studied.

Propagation of Quantum Light through Media

Quantized fields in macroscopic media, e.g., semiconductors are analyzed. The propagation of quantum light through the turbulent atmosphere is studied.
