The quantum network is a fundamentally new information infrastructure, which promises an exponential speed up in computing and an unconditionally secure communication. The key challenges to achieve quantum network are security, distance and practicality. I will address our recent efforts to solve these challenges. I will primarily talk the recent experiments on high-rate and chip-based quantum communication, and the implementations of measurement-device-independent, twin-field and device-independent QKD protocols. Further details can be seen in [Xu et al., RMP 92, 025002 (2020)].


Feihu Xu has been a Full Professor of Physics at USTC since 2021. Before joining USTC in 2017, he was a Postdoctoral Associate at MIT in 2015-2017. He received an M.A.Sc and Ph.D from University of Toronto in 2011 and 2015. He works on quantum information science and single-photon imaging, and has co-authored more than 100 journal papers including Rev. Mod. Phys., Nature, Nat. Photon., Phys. Rev. X, etc. He is the fellow of the Optica and IOP. He is the recipient of Xplorer Prize, International Quantum Technology Early Career Scientist Award, Changjiang Scholar, and MIT Technology Review 35 Innovators Under 35 of China. He serves as the Associated Editor for npj Quantum Information and the editor board for PRX Quantum.
