A Teleportation Scheme Based on Quantum Signature
Dong Ding · Journal of Hebei Normal University · 2011
A teleportation scheme based on quantum digital signature,in which a GHZ state is used as the quantum channel,is proposed.In this protocol,the sender teleports a one-particle state based on the availability of an honest arbitrator,the keys are shared by the communication parties and the arbitrator.The key point is that the fact of the teleportation can neither be disavowed by the sender nor be denied by the receiver.
