Personal Biography

I have long been devoted to experimental research in the field of quantum computation based on superconducting quantum circuits. My main innovative research achievements include: 1) the development and implementation of quantum control methods with high-fidelity, high-robustness, and high-scalability for superconducting qubits; 2) the realization of real-time repetitive quantum error correction for a logical qubit encoded in a bosonic mode, which extends the quantum information lifetime beyond the break-even point for the first time, representing a key step towards fault-tolerant quantum computation. 3) the efficient generation of large Fock states with up to 100 photons, which are utilized to achieve Heisenberg-limited quantum metrology.

I have published over 30 academic papers in top international journals, including Nature, Nature Physics, Physical Review Letters, etc. Among these 12 papers are published as the first author or corresponding author (including 1 in Nature, 1 in Nature Physics, 1 in Nature Computational Science, 6 in Physical Review Letters, and 1 in Physical Review Applied). The total citations of these works from Google Scholar exceed 2800 with an h-index of 24 as of Nov. 2025.
