Abstract

Based on the second-order quantum interference between frequency entangled photons generated via parametric down conversion process, we have demonstrated a new experiment of synchronizing two clocks separated by 6-km fiber link. A synchronization accuracy of 13 ps has been achieved with a minimum timing stability of 60 fs.
