Assistant Researcher Institute for Quanfum Science and Engineering

Graduated from the School of Physics, Peking University in 2012 with bachelor's degree; and from IIIS, Tsinghua University in 2018 with Ph.D. degree. My research interest mainly lies in developing quantum computation platform based on trapped-ion system.
