Overview of Academic Research
Prof. Zhang Liang's research focuses on systematic studies in the field of space quantum communication. His work addresses core challenges such as high-precision pointing, acquisition, and tracking for satellite-ground quantum optical links and space quantum communication and optical communication networking.
His major achievements include:
Proposed and implemented sub-microradian precision optical tracking and pointing technology for satellite-ground links, overcoming the challenge of establishing high-efficiency quantum links under satellite dynamic disturbances. This technology was successfully applied to the world's first quantum science experiment satellite, Micius .
Developed polarization spatial phase compensation and polarization basis correction methods , enabling high-precision polarization state preservation in complex opto-mechanical systems.
Constructed an optical transmission system suitable for space quantum key distribution (QKD) networking and developed the optical transmission unit for the world's first quantum micro/nano-satellite.
