Alessandra Gatti is a senior researcher of the Institute of Photonics and Nanotechnologies of CNR. She graduated in Physics cum laude in 1993 at the University of Milano (Italy) and obtained her PhD in Physics in in 1997 from the same university. After some postdoctoral grants, in 1999 she became a permanent researcher at the National Institute for the Physics of Matter, which later merged into the CNR. Since 2010 she is a senior researcher of IFN-CNR. In 2013 (and again in 2019) she qualified to full professorship in theoretical physics of matter; from 2013 to 2019 she was adjunct professor of “Quantum Optics” at the University of Insubria in Como (Italy). In 1996 she had a 4-month research fellowship in the group of S. M.Barnett and G.L Oppo at Strathclyde University (Glasgow, UK), and in 2015 she was visiting researcher at Institut Non Linéaire de Nice (France).
Since her PhD, she participated to several European projects, and was the scientific coordinator of the FP7 project HIDEAS, High Dimensional Entangled Systems (FET OPEN program, 2008-2012). She coauthored more than 150 scientific papers in the field of quantum and nonlinear optics, and presented her work in > 60 scientific events worldwide. In 2014 she became a fellow of Optica (formerly Optical Society of America) «for pioneering contributions to the field of quantum imaging » and in 2013 she received from the European Physical Society the Emmy Noether distinction for Women in Physics.

A.G. carries out theoretical research in the field of quantum and nonlinear optics. The focus is on the multimode and multipartite entangled states of light generated by broadband nonlinear optical processes, and on their applications to quantum imaging and sensing. In collaboration with different experimental groups, she gave several contributions to these topics, including: the analysis of the borderline between the classical and quantum domains in the so-called ghost imaging technique; the introduction of differential ghost imaging and the demonstration of its use for efficient imaging in disordered media; the first demonstration in theory and experiments of a spatial quantum correlation of the twin beams generated by parametric down-conversion; the theory of sub-shot noise imaging; the study and demonstration of the X-entanglement, i.e. of the X-shaped spatio-temporal correlation of twin beams and twin photons, involving a ultranarrow correlation time (femtosecond range).
Her current research focuses on the possibility of enhancing nonlinear light-matter interactions (multiphoton absorption, Raman scattering, second-harmonic generation …) by light entanglement, and to the applications to entangled 2-photon and SHG microscopy. In this framework, she coordinates the italian PRIN project 2022K3KMX7 “ELISE -Enhancing multiphoton Light-matter Interactions with Space-time Entanglement ” (2023-2025)
