QUCHIP: Quantum Simulation on a Photonic Chip
Simulation is a fundamental computational tool for modern science with applications ranging from drug design to materials science. Quantum simulators have the potential to revolutionize the way simulations are performed by accessing system sizes that are untractable in classical machines. As a result, they will become a suite of powerful and ...

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 ...
