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. This includes analyses of highly multimode entanglement between arbitrary degrees of freedom and their role in quantum metrology. Experimentally accessible quantum process reconstruction techniques are formulated, and experimental scenarios are simulated to optimize the performance of quantum devices.
