In the standard teleportation protocol,the direct transfer of a quantum system from a sender to a receiver can be perfectly simulated by the transfer of a finite amount of classical bits,provided that the sender and the receiver share a sufficient amount of entanglement.Extending this idea to a different scenario,one can take a quantum version of Eddingtons clock synchronization--where a quantum clock is transferred from the sender to the receiver--and try to convert it into a new protocol where the direct transfer of the clock is replaced by the use of entanglement along with the transfer of classical bits.
