基于可重用GHZ态作为安全载体的量子秘密共享

Quantum secret sharing based on reusable GHZ states as secure carriers

Saber Bagherinezhad, Vahid Karimipour

摘要:

介绍了一种基于可重用纠缠态的量子秘密共享协议。发送器和接收器之间的纠缠态仅作为一个载体,发送器将数据比特纠缠到该载体上,接收器将数据比特从该载体上解纠缠,所有这些都是通过简单门的局部动作实现的。我们还表明,拦截夏娃或作弊的接收器之一引入了量子误码率(QBER)大于25%,可以通过比较比特的子序列来检测。

英文摘要:

We introduce a protocol for quantum secret sharing based on reusable entangled states. The entangled state between the sender and the receiver acts only as a carrier to which data bits are entangled by the sender and disentangled from it by the receivers, all by local actions of simple gates. We also show that the interception by Eve or the cheating of one of the receivers introduces a quantum bit error rate (QBER) larger than 25 percent which can be detected by comparing a subsequence of the bits.
