Alessandro Zavatta was born in 1973 and he is a research scientist at the Istituto Nazionale di Ottica (INO) of the Consiglio Nazionale delle Ricerche (CNR) since 2008.

He received his Laurea degree (M.Sc.) in Physics from the University of Bologna in 1999, and his Ph.D. degree from the University of Firenze in 2003. During the M.Sc., he received a Diploma in Physics at University of Kent (UK) supported by EU-ERASMUS scholarship.

In 2013 and 2014 he received the Italian Habilitation for Associate Professor for Experimental and Theoretical Matter Physics.

In 2016-2019 he was short-term invited Professor at Université Nice Sophia Antipolis, Nice, France.

RESEARCH ACTIVITIES AND SCIENTIFIC PRODUCTION

His research activities fall in the emerging field of quantum technologies and concern the quantum engineering of light, spacing from fundamental tests of quantum mechanics to the realization of innovative quantum optical devices. In particular, his main achievements include the realization of an ultrafast homodyne detection apparatus to characterize nonclassical states of light. The first experimental realization of the quantum creation operator obtained by single-photon addition using parametric amplification and complex superpositions of creation and annihilation operators that lead to prove the quantum commutation rules and noiseless amplification of quantum light states. He has demonstrated the realization of a new kind of hybrid-entangled states of light, where a single-photon state is entangled with a coherent one. Among the several contributions in the generation, manipulation and characterization of quantum states of light, he has demonstrated an efficient, compact and “plug & play” source of squeezed states of light compatible with telecommunications optical fibre networks and ready to be used for quantum communication protocols.

He is co-author of more than 60 papers (first author in 25 of them) published in peer-reviewed top international scientific journals (among which, 2 Science, 2 Nature Photonics, and 11 Phys. Rev. Lett. papers), and more than 20 (10) conference contributions as (invited) speaker. From ISI Web of Science his publications are recognized with more than 1800 citations with an H-factor of 20.
