Tang Jianshun, Associate Researcher, has been with the Key Laboratory of Quantum Information at the Chinese Academy of Sciences since 2006. Under the mentorship of Academician Guo Guangcan and Professor Li Chuanfeng, he is now a key member of Professor Li Chuanfeng’s Quantum Entanglement Network Research Group. For many years, he has been engaged in research on quantum dots and quantum entanglement networks, accumulating rich research experience. He has published over ten papers in SCI journals such as Nature Photonics, Physical Review X, and Physical Review Letters. He was the first to complete the quantitative measure of non-Markovianity of single photons in optical fibers, a work highlighted by Europhysics Letters as a high-profile article in 2012. He also realized the quantum Wheeler’s delayed-choice experiment, creating a quantum superposition state of wave and particle nature, reinterpreting wave-particle duality and breaking the traditional limits of Bohr's complementarity principle. His research has been reported by Nature Photonics, Nature Physics, New Scientist, and Nature China. Recently, he has been a key participant in the experiment of single-photon docking between two solid-state nodes (quantum dots and solid-state quantum memory) in a quantum network. This is a fundamental step in building quantum entanglement networks and will have profound impacts on the field of quantum networks and quantum information.
