Photon-subtracted graph states

Mattia Walschaers

Laboratoire Kastler Brossel

Mattia Walschaers is a post-doctoral researcher at the Laboratoire Kastler Brossel in Paris. After doing a PhD on benchmarks for quantum transport in complex systems, his research is now centred on continuous-variable quantum optics. As a theorist in an experimental group, he develops a theoretical framework for studying multimode non-Gaussian states, in particular those that can be experimentally generated through photon-subtraction. On the level of methods, he merges tools from quantum statistics mechanics with more standard aspects of quantum optics.


Quantum entanglement, one of the key resources for quantum information processing, can be deterministically generated in a scalable manner in continuous variable (CV) systems. However such CV entangled states typically display... [ view full abstract ]
