Abstract

Optical clock networks promise advances in global navigation, time distribution, coherent sensing, relativity experiments, dark matter searches and other areas1–12. Such networks will need to compare and synchronize clocks over free-space optical links. Optical two-way time- frequency transfer (O-TWTFT) has synchronized clocks to 10^-19 in frequency and
