Alessandro Gagliano was born in December 1997 in Como, Italy. He received his B.Sc. degree in Engineering Physics in 2019 and his M.Sc. degree cum laude in Telecommunication Engineering in 2021, both from Politecnico di Milano. In his thesis, Alessandro deeply analysed the integration between quantum and classical signals in shared optical links, including theoretical and experimental evaluations with a focus on the spontaneous Raman scattering impact. From February 2022 to October 2022, he was a temporary research fellow at the Optical Communication Laboratory (PoliCom) of Politecnico di Milano within the FIRST project, where he investigated the performance of quantum communication systems in innovative photonic solutions based on space-division multiplexing. Since November 2022, he has been attending the Ph.D. program in Information Technology offered by the Department of Electronics, Information and Bioengineering of Politecnico di Milano. His doctoral research interests focus on quantum key distribution protocols and optical infrastructure for integrated quantum-classical networks.
