Dr. Keyu Xia is a full professor working at the College of Engineering and Applied Sciences, Nanjing University. He received his Doctoral degree of 'Optics” in 2007 from Shanghai Institute of Optics and Fine Mechanics, CAS. After postdoctoral research in Max-Planck Institute for Nuclear Physics in Germany, in Texas A&M University in USA, and in Macquarie University in Australia, he was offered the professor position and joined Nanjing University. Dr. Xia's research interests focus on the fields of quantum optics and quantum information, in particular, superconducting quantum circuits, quantum network, quantum metrology and quantum nonlinear optics. He has more than 30 peer-reviewed publications in the top-level journals including Nature Photonics, PRL, PRX and so on. His works have been reported by Science Magazine, Nature Photonics and media Phys.Org. The theoretical proposals for single-photon isolation have been experimentally realized by the Vienna Center of Quantum Science and Technology. His recent work of 'Thermal-motion-induced quantum optical system”, published in Nature Photonics, is selected as 'Top-10 progresses of Optics in China in 2018-Fundamental Research”. Dr. Xia was awarded the honor of 'Outstanding Reviewer of J. Phys. B” by IOP in 2018.
