摘要
提出了重复使用纠缠W态的量子秘密分享方案.在该方案中,发送方和接受方之间的纠缠W态作为载体,发送方将数据比特与这一载体产生纠缠,再由接受方解除纠缠而最终获得秘密消息.所有这些都由一些简单逻辑门来完成.研究结果表明,窃取或联手欺骗成功的可能性都非常小.
A protocol for quantum secret sharing by reusing entangled W state is proposed.In this protocol,the entangled W state between the sender and the receivers acts as a carrier.The data bits are entangled to the carrier by the sender and disentangled from it by the receivers who get the secret message in the end.All of these can be achieved by the actions of simple gates.Finally,it shows that the possibility of success in interception or cheating by one of the receivers is very small.
