Title: Quantum information processing with photons and atoms

The nonlocality and intrinsic randomness of quantum entanglement not only deepen our understanding of the laws of quantum world, but also give rise to emerging quantum information technologies, including quantum communication and quantum computation, which can ensure secure information exchange and greatly enhance the computing power, respectively. I will introduce how to experimentally test quantum entanglement and how to turn quantum information technology from purely theoretical concepts into reality. Specifically, how to overcome the security loopholes caused by imperfection of realistic devices, how to extend the distance of quantum communication, and how to use the coherent manipulation of multiple qubits to achieve a quantum computer that can surpass classical supercomputers. I will also introduce the future prospects of the global quantum communication network and its new applications in the field of quantum metrology, as well as the development roadmap of quantum computing.

About Jian Wei Pan
Jian-Wei Pan, born on 11 March 1970, received his Bachelor (1992) and Master (1995) in Physics from the University of Science and Technology of China, Hefei, and his PhD (1999) from the University of Vienna. He is currently a Professor of Physics at the University of Science and Technology of China, an Academician of Chinese Academy of Sciences (CAS), a Fellow of the World Academy of Sciences (TWAS) and a foreign member of the Royal Society (London). He serves as the Director of the CAS Center for Excellence in Quantum Information and Quantum Physics.

Prof. Jian-Wei Pan’s research fields focus on quantum foundations, quantum optics and quantum information. Pan pioneers in multi-particle interferometry and quantum experiments in space. He closed major loopholes for secure quantum communication associated with imperfect devices, making it a viable technology under realistic conditions. He group developed the quantum satellite Micius, demonstrated the first intercontinental quantum communication. These pioneering efforts bring global-scale secure quantum communication from a purely theoretical concept to reality. His group demonstrated quantum computational advantage, validating the feasibility of quantum computing systems to outperform classical machines in solving specific problems. He has also conducted a series of studies in quantum simulation with ultracold gas, including research on synthetic gauge potentials, atom-atom entanglement, ultracold molecular chemistry, and quantum simulation of the Fermi-Hubbard model.
