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.

On 2010 she joined as a post-doc the group led by Philippe Granger at the Institut d’Optique. She worked on the project which aims to implement non-linear effects at the single photon level by exploiting the long-range interactions in ensemble of Rydberg atoms.

On 2013 she worked as a post-doc with Julien Laurat at LKB  on an atomic quantum memory for vector beams. On 2014 she worked with Valentina Krachmalnicoff and Yannick De Wilde on near-field 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 currently involved in the implementation of complex quantum networks in a multi-mode continuous-variables scenario and she has been recently (2018) awarded 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.
