His main research areas are
1. Study on topological phase and corresponding properties. This paper explores the characterization and description of corresponding topological properties in lattice model, and applies the corresponding properties of topological physics to quantum information technology to realize effective topological quantum computation.
2. Research on quantum random walk properties. On the one hand, the properties of topological systems are simulated based on quantum random walk systems. On the other hand, the quantum random walk system is used to realize the effective quantum information transmission process.

one Research on the Properties of topological States Based on Circuit Systems
The ground state of kitaev toric code model is constructed by using microwave circuit system simulation, and the topological phase transition resulting from the enhancement of external field intensity is further observed [Nat.Commun. 10, 1557 (2019)]. Non-hermitian lattices are constructed using circuits to demonstrate a hybrid topology-skin boundary model driven by skin effects [Nat.Commun. 12, 7201 (2021)].
two Research and Application of topological Properties Based on Optical Systems
Anomalous topologically protected boundary states of two-dimensional quantum random walks have been experimentally observed for the first time in an optical system in free space [PRL 121, 100501 (2018)]. Using optical systems, a quantum random walk system with special boundary is constructed to demonstrate novel non-Hermitic topological boundary states [Laser Photonics & Reviews 14, 2000092 (2020)]. And high-fidelity entangled state transmission and transformation [Laser Photonics & Reviews 16, 2100519 (2022)].
Three. Experimental implementation of quantum algorithms
Performing quantum algorithms in a circuit. We have experimentally implemented a Quantum algorithm based on graph structure [Research, 2021, 9793071 (2021); Advanced Quantum Technologies 5, 2100143 (2022)].
