Kui Zhao

　　Kui Zhao received a bachelor's degree from Central South University and a Ph.D. from the Institute of Physics, Chinese Academy of Sciences (IOP, CAS). He is currently a postdoctoral researcher at the Beijing Academy of Quantum Information Sciences (BAQIS). His research focuses on the development of quantum measurement and control systems for cloud quantum computing platforms (CQCP), as well as quantum computation and simulation experiments based on superconducting quantum chips. He has extensive experience in building measurement and control systems for multi-qubit CQCPs, automated calibration, and quantum simulation. His research interests include the experimental realization of high-fidelity2(3)-qubit gates, the implementation of spin Hamiltonians based on Trotter decomposition and Floquet engineering, and quantum simulation.
