Xiu-Hao Deng, Associate Researcher (assistant professor, PI) of Institute of Quantum Science and Engineering in SUSTech, adjunct associate researcher of Center for Quantum Computing in Peng Cheng Lab. He obtains B.S. in 2005 from the Department of Modern Physics, University of Science and Technology of China (USTC). After several years of study and research in USTC, he went to the University of California, Merced for graduate school, and obtained Ph.D. in 2015. After he finished a short-term research associate at UC Merced he joined Sophia and Ed Barnes's joint group in VirginiaTech as a postdoctoral associate. He returned to China in late 2018 and started his position in the institute in December.

During the 9-year study and research in the US, Xiu-Hao produced original work in quantum control theory and quantum dynamics. He also did some creative work in a superconducting quantum circuit, superconducting qubits, and quantum simulation. He participates in two major projects at the province level. He organized several international conferences including a premier one, QIP 2020.
