论文摘要
在本文中，我们提出了一项量子通信协议，以达成多个各方之间的拜占庭一致性。与现有协议相比，我们的提案的引人注目的特征是，我们不使用纠缠来达成协议。我们的协议中有两个阶段。在第一阶段，一组通过量子安全通信将满足某些特殊属性的数字列表分配给每个参与者。然后，在第二阶段，这些参与者交换了一些信息以达成协议。
In this paper we propose a protocol of quantum communication to achieve Byzantine agreement among multiple parties. The striking feature of our proposal in comparison to the existing protocols is that we do not use entanglement to achieve the agreement. There are two stages in our protocol. In the first stage, a list of numbers that satisfies some special properties is distributed to every participant by a group of semi-honest list distributors via quantum secure communication. Then, in the second stage those participants exchange some information to reach agreement.
