Personal Biography

I have long been devoted to experimental research in the field of quantum information, focusing on continuous-variable quantum optics and superconducting quantum circuit systems. My main innovative research achievements include: 1) the efficient generation of large Fock states with up to 100 photons, which are utilized to achieve Heisenberg-limited quantum metrology; 2) the generation and amplification of squeezing state in superconducting quantum circuit, which are utilized to achieve Heisenberg-limited quantum metrology. 3) the demonstration of monogamy relation for Einstein-Podolsky-Rosen steering in Gaussian Cluster states.

I have published over 20 academic papers in top international journals, including Nature, Nature Physics, Physical Review Letters, etc. Among these 8 papers are published as the first author or corresponding author (including 1 in Nature Physics, 1 in Physical Review Letters). I have been honored with awards such as the Wang Daheng Optics Award. Additionally, I have led projects including the National Natural Science Foundation Youth Fund and General Program.
