Descrizione

Matteo G A Paris , born in Milano, 15 July 1967.

Matteo G A Paris is associate professor at the Department of Physics, University of Milano, where he founded and lead a research group currently composed of seven persons, working on quantum information, quantum optics and foundations of quantum mechanics. He got his Ph.D. at the University of Pavia, and then worked two years as a post-doc in the group "Nichtklassiche Strahlung" of the Max-Planck-Society (Berlin). Before joining UniMi he was research fellow of the University of Pavia and INFM research associate.

He is a theoretician working in close collaborations with experimentalists on quantum information and quantum optics. In these fields he is author of about 200 publications, which received more than 2300 citations, with 35 invited talks and seminars; his H-index is currently 27. His main contributions are in the fields of quantum estimation of states and operations, generation and application of entanglement, quantum information processing, interferometry and high-precision measurements.

Matteo Paris suggested and developed the method of Quantum Tomography to reconstruct the density matrix of a physical system from the measurement of a set of observables. The method, originally developed for the radiation field, has been then generalized to an arbitrary system and received several experimental confirmations. The original paper about Quantum Tomography actually received more than 180 citations and actually originated a new research field, as witnessed by a successful volume of the Springer series "Lecture Notes in Physics", of which MGAP has been the editor. MGAP suggested and developed many scheme based on quantum entanglement to improve high-precision measurement, quantum state engineering and quantum commununication. His PRL about the use of entanglement in high-precision measurement received more than 80 citations and has been implemented in many different physical systems. In 2004 MGAP and his group proposed a novel method to reconstruct the photon statistics of the radiation field using only on/of detectors. The method has been implemented soon after for single and two-mode beams and the corresponding papers has been published on PRL and Opt Lett in 2005 and 2006. Recently he suggested a novel method to estimate entanglement of a pair qubits with the ultimate precision allowed by quantum mechanics. The method has been implemented in collaboration with the italian metrological labs and the paper has been published on PRL at the beginning of 2010. The recent activity of MGAP is focused on the role of nonGaussianity in quantum information processing with continuous variables, in the analysis of quantum correlations other than entanglement and in the behaviour of open quantum system in the presence of structured reservoirs.
