Nonclassicality
The characterization and application of nonclassical effects is studied, based on the full information on a given quantum state.
Nonclassicality conditions are derived and related to observation principles.
In particular we are interested in quantum effects due to nonclassical radiation fields.

Entanglement
Entanglement is the key resource of Quantum Information Technologies.
The characterization and detection of entanglement is studied.
New algebraic methods are derived and applied.

Cavity QED
We are dealing with the description of realistic cavities by taking into account the unwanted scattering and absorption losses.
The strong atom-field coupling under such conditions is of particular interest.
The entanglement effects of cascaded systems of cavities are studied.

Propagation of Quantum Light through Media
We have combined methods of field quantization in macroscopic media with the microscopic theory of semiconductors.
Another situation is the propagation of nonclassical light through the turbulent atmosphere.
