摘要
提出了利用三粒子最大纠缠态作为信道的量子信息签名的隐形传态方案.方案中引入一个忠实的第三方作为公证,发送方传输一个单粒子态给接收方.通讯双方与公证人间各自建立密钥,从而保证通讯双方对传态的发送或接收过程不可抵赖.
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.
