A research team led by Prof. Chang Hong from the National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS) has developed a strontium optical lattice clock with both frequency stability and systematic uncertainty surpassing 2--10-18. This achievement places China among the global leaders in the field of optical lattice clock development.
