Distant Clock Synchronization Using Entangled Photon Pairs
arXiv:quant-ph/0407204 · doi:10.1063/1.1797561
Abstract
We report a proof-of-principle experiment on distant clock synchronization. Besides the achievement of picosecond resolution at 3 kilometer distance, this experiment demonstrated a novel concept for high accuracy non-local timing and positioning based on the quantum feature of entangled states.
