    "abstract": "A protocol for synchronizing distant clocks is proposed that does not rely on\nthe arrival times of the signals which are exchanged, and an optical\nimplementation based on coherent-state pulses is described. This protocol is\nnot limited by any dispersion that may be present in the propagation medium\nthrough which the light signals are exchanged. Possible improvements deriving\nfrom the use of quantum-mechanical effects are also addressed.",
