Quantum photonics in the time and frequency degrees of freedom

Abstract
Light offers several degrees of freedom to encode qubits: of these the time and frequency degrees of freedom are compatible both with long distance propagation using fiber networks and elaboration of information using integrated optics and telecom components. In this seminar I will present how to generate entangled states in frequency and time using on-chip components. I will then discuss QKD protocols using both degrees of freedom. I will conclude presenting a gaussian boson sampling experiment sampling time-frequency modes of entangled pairs generated on a chip.
Bio Daniele Bajoni obtained his PhD degree in 2004 from the University of Pavia with a dissertation on optical spectroscopy of photonic crystals and microcavities. After holding a post-doc position at LPN-CNRS (FR), he obtained a tenure position as assistant professor in experimental solid-state physics at the University of Pavia, where he was appointed associate professor in 2014. His research interests include strong light-matter interaction and experimental quantum photonics. He has demonstrated several devices for quantum optics integrated in silicon chips, including a micrometric source of entangled photon pairs. Overall, he is co-author of more than 80 journal publications with more than 2000 citations, and an H-index of 26 (Scopus).
Daniele Bajoni teaches Basic Electromagnetism (Fisica 2) and Introduction to Quantum Mechanics and Quantum Technologies.
