TRR 142 - Generation and characterization of quantum light in nonlinear systems: A theoretical analysis (C10*)
We develop novel approaches based on integro-differential equations and quantum-channel descriptions for the tailored generation of nonclassical light and its propagation in structured media. By devising a multilinear process matrix formalism and accounting for complex dispersion in photonic crystals, we characterize quantum properties of light. ...

Semiconductor quantum wells excited by non-classical states of light: Interplay between photonic quantum correlations and many-body interactions in solid state systems
Compared to atomic systems, the theoretical description of the optical properties of bulk semiconductors and nanostructures is significantly more complex but also much richer and over a wide range designable by the choice of the nanostructure geometry and the material composition, e.g., in quantum wells. Whereas in atoms the electronic states are ...

TTR 142 - Integrated SU(1,1) interferometers (C02)
The primary goal of this project phase is to develop LiNbO3 based integrated circuits for quantum metrology applications. Based on LiNbO3-tool box components developed in the first phase of the project, we plan to develop integrated non-linear SU(1,1) interferometers in different configurations. Such interferometers are a very promising tool for ...
