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. ...

Quantum Correlations of Light and Matter: Quantification and Application (B12, Subproject of SFB 652: Strong Correlations and Collective Effects in Radiation Fields: Coulomb Systems, Clusters and Particles)

In this project, methods for the identification of quantum correlations of fermionic, bosonic and many-party systems will be developed. To this end, a universal quantification of entanglement and nonclassicality will be introduced for arbitrary spatially and temporally dependent systems. Operational measures will be constructed that characterize ...
