Ultra-Precise Clock Synchronization via Distant Entanglement

Abstract

We have demonstrated a spectrally bright source of entangled photon pairs that are necessary for transferring entanglement from photons to a pair of atoms at significant distance. We have shown how a measurement of the degree of entanglement may be used to deduce the relative speed between two frames, without direct measurement of velocities.
