We complement our colleagues in China on their fantastic experiment published in Entanglement in composite quantum systems can be regarded as the most genuine trait of quantum physics. Quantum networks and communications will enhance and accelerate optical and electronic communication, while quantum computing could radically enhance Information Technologies. In recent years, miniaturization of optical elements, sources and detectors have allowed a full integration of very complex optical circuits in tunable photonic chips. His thesis is about the work on the lattice project, with title of "Two- and four-body spin-exchange processes in optical lattices". The position will be part of he theoretical quantum optics group, which investigates a broad range of topics in theoretical quantum optics and quantum information.
