Clock synchronization with dispersion cancellation - art. no. 117902

The dispersion cancellation feature of pulses which are entangled in freque ncy is employed to synchronize clocks of distant parties. The proposed prot ocol is insensitive to the pulse distortion caused by transit through a dis persive medium. Since there is cancellation to all orders, also the effects of slowly fluctuating dispersive media are compensated. The experimental s etup can be realized with currently available technology, at least for a pr oof of principle.
