The generation of optical quantum states on an integrated platform will enable low-cost and accessible advances for quantum technologies such as secure communications and quantum computation. We demonstrate that integrated quantum frequency combs (based on high-Q microring resonators made from a CMOS-compatible, high refractive-index glass platform) can enable, among others, the generation of pure heralded single photons, cross-polarized photon pairs, as well as bi- and multi-photon entangled qubit and quDit states over a broad frequency comb covering the S, C, L telecommunications band, constituting an important cornerstone for future practical implementations of photonic  quantum information processing.


Roberto Morandotti received a M.Sc. in Physics from the University of Genova (Italy) in 1993, and a Ph.D. degree from the University of Glasgow (Scotland) in 1999. From 1999 to 2001, he was with the Weizmann Institute of Science, Rehovot, Israel, and from 2002 to 2003, he was with the University of Toronto, Toronto, ON, Canada, where he worked on the characterization of novel optical structures. In June 2003, he joined the Institut National de la Recherche Scientifique-Centre Energie, Materiaux et Telecommunications (INRS-EMT), Université du Quebec, Montreal, QC, Canada, where he has been a Full Professor since 2008.

He is the author and coauthor of more than 750 papers in international scientific journals (>200, including over 50 contributions to Physical Review Letters, Nature, Science, Nature Photonics, Science Advances, Nature Communication and Physics Report) and conferences. His research interests deal with the linear and nonlinear properties of various structures for integrated optics, nonlinear and quantum optics as well as with nonlinear optics at unusual wavelengths (e.g., THz). Dr. Morandotti is currently serving and/or has served as a Technical Committee Member and a Chair for several Optical Society of America (OSA), Lasers and Electro-Optics Society, IEEE and SPIE meetings. He is an E.W.R. Steacie Memorial Fellow (the most prestigious award for young scientists in Canada), a Fellow of the Royal Society of Canada, and a Fellow of the OSA, APS, SPIE among others.
