The combination of optical time transfer and optical clocks opens up the possibility of large-scale free-space networks that connect both ground-based optical clocks and future space-based optical clocks. Such networks promise better tests of general relativity1–3, dark-matter searches4 and gravitational-wave detection5. The ability to connect optical clocks to a distant satellite could enable space-based very long baseline interferometry6,7, advanced satellite navigation8, clock-based geodesy2,9,10 and thousandfold improvements in intercontinental time dissemination11,12. Thus far, only...

Scientists are on a mission to create a global network of atomic clocks that will enable us to, among other things, better understand the fundamental laws of physics, investigate dark matter, and navigate across Earth and space more precisely.

An optical link for communication between distant atomic clocks is 100 times more stable than previous links and could enable new precision tests of general relativity.
