Overview of Academic Research
Professor Chen’s main research direction is quantum key distribution. He has published more than 100 SCI papers in journals such as Nature Photonics, Nature Communications, and Physical Review X, and was invited to contribute one chapter to Chinese and English monographs respectively. Key research achievements include: completing representative works such as hundred-kilometer loopback differential phase and 830-kilometer two-field quantum key distribution. Developing practical quantum cryptography equipment with a frequency reaching 5 GHz. As the technical leader, constructing multiple field quantum secure communication networks, including the "Beijing Four-User Network", "Quantum Government Network", and "Hefei-Wuhu Intercity Network". In the research of integrated optical quantum communication devices, designing and developing a polarization-independent silica waveguide optical quantum encoder-decoder, verifying a 1.25 GHz repetition rate time-bin encoding system using the self-designed integrated optical quantum encoder-decoder, proposing an integrated device scheme for SOI (silicon-on-insulator) chips where loss is independent of modulation phase, putting forward an induced photorefractive attack scheme for lithium niobate waveguide devices, and completing the first quantum communication experiment using an on-chip optical soliton source and high-quality HOM interference with an independent on-chip optical soliton source.
