Multi photon entangled states based on integrated frequency combs.



报告人:加拿大魁北克大学Roberto Morandotti教授




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 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.


Prof Morandotti received a MSc in Physics from the University of Genova (Italy) in 1993 and a PhD in Electronic Engineering from the University of Glasgow (Scotland) in 1999, where his research activity focused on the study of the linear and nonlinear properties of optical discrete systems.In June 2003 he joined INRS-EMT (University of Quebec) in Montreal, where he is a Full Professor since 2008. His research interests mainly deal with the linear and nonlinear properties of periodic structures, both in III-V semiconductors and silica, as well as with optics at unusual wavelengths, including THz. Prof Morandotti is author and coauthor of more than 700 papers in scientific journals and conferences (including 15 in Nature, Science, Nature Photonics, Nature Physics, Nature Communication and Science Advances, as well as 34 in Physical Review Letters) and gave over 100 invited keynote and plenary talks in various international conferences. He is currently serving/ has served as a subcommittee chair/technical committee member for several OSA, IEEE and SPIE meetings. Prof Morandotti is an E.W.R. Steacie Memorial Fellow 2011 (awarded to the 6 best early career scientists in Canada), a Fellow of the Royal Society of Canada, a Fellow of the Optical Society of America, a Fellow of the American Physical Society, a Fellow of the Institute of Physics and a Fellow of the SPIE, among others.
