Experts used China's quantum satellite - Quantum Experiments at Space Scale (QUESS) - to verify quantum-secure time transfer for the first time, which laid a foundation for building a safe satellite navigation system. The study published on Nature Physics was jointly accomplished by Professor Pan Jianwei from the University of Science and Technology of China and his colleagues. High-precision time synchronization plays an important role in fundamental science and real-life applications, including navigation and positioning.
