Valentina Parigi obtained her PhD at LENS (European Laboratory for Non-Linear Spectroscopy) in Florence under the supervision of Marco Bellini. During her PhD she worked on  generation, manipulation and characterization of non-classical states of light and she realized the first experimental test on quantum commutation rules. She then worked on non-linear effects at the single photon level by exploiting the long-range interactions in ensemble of Rydberg atoms,  atomic quantum memories and near-field characterization of disordered nanostructures.

She is Full Professor since 2023 and had been Associate Professor (2015-2023)  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 multi-mode continuous-variables 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.
