Abstract

We propose a quantum-enhanced two-way time transfer protocol by using frequency entangled pulses to enhance accuracy compared with their classical analogues. It can be shown that the measurement accuracy of the time offset can achieve the order of femtosecond which is determined by the width of the fourth-order correlated function and is immune from the effect of the path length change.
