Valentina Parigi obtained her PhD at LENS (European Laboratory for NonLinear Spectroscopy) in Florence under the supervision of Marco Bellini. During her PhD she worked on generation, manipulation and characterization of nonclassical states of light and she realized the first experimental test on quantum commutation rules. She then worked on nonlinear effects at the single photon level by exploiting the longrange interactions in ensemble of Rydberg atoms, atomic quantum memories and nearfield characterization of disordered nanostructures.
Since 2015 she is Associate Professor in the Quantum Optics group at LKB, working in the Multimode Quantum Optics team.
She is leading the activity on complex quantum networks in a multimode continuousvariables scenario, awarded (2018) with an – ERC Consolidator Grant.
Her interests range from the foundations of quantum mechanics to the experimental implementation of basic tools for quantum information technologies.
