[Seminar] Quantum nonreciprocity and applications

Prof. Keyu Xia from Nanjing University

Abstract:

Nonreciprocity in the quantum regime can reveal exotic physics breaking the time-reversal symmetry and also paves the way for unconventional quantum information processing. This presentation will introduce three principles for achieving quantum nonreciprocity and show applications in optical and single-photon isolation, quantum computation.

Biography:

Dr. Keyu Xia was awarded the doctorate in “Optics” in 2007 by Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences. Now, he is a full professor working in Nanjing University, China. His research interest concentrates on the fields of cavity QED, quantum nonreciprocity and chiral quantum optics. He has more than 80 peer-reviewed publications in the renowned journals, including Science, Nature Photonics, Science Advances, PRL, PRX, and Nature Communications. His works have shown high impact in review papers and news/perspective published in Science, Nature, Nature Photonics and Reviews of Modern Physics, and have also been reported by many scientific media such as Physics World and Phys.Org. He revealed three mechanisms for conducting chiral quantum optics and quantum nonreciprocity.
