摘 要: 根据量子隐形传态基本特性,研究可控量子隐形传态、Greenbergey-Horne-Zeilinger (GHZ)纠缠粒子对、密度编码与量子网络编码的融合特性,提出利用2对非最大化GHZ纠缠粒子在蝶形网络中传输2-level量子纠缠态的量子网络编码方案,从而解决量子网络中传输效率及安全问题。在该方案中,所有的传输信道都是量子信道,由于采用了可控量子隐形传态的技术,可以保证此方案的传输效率能够达到100%.

Abstract: Based on ideas of quantum teleportation, controlled quantum teleportation, Greenbergey-Horne-Zeilinger (GHZ) entangled state and the characteristics of the quantum network coding was studied. In order to solve the problems of transmission and security of messages in quantum network, a scheme which transmits two 2-level quantum states crossly over the butterly network with two non-maximally entangled GHZ pairs shared by two senders was proposed in this paper. In this protocol, all the channels are the quantum channels. Since the controlled quantum teleportation was adopted in this scheme, the intrinsic efficiency for particles in this scheme was 100% in principle.
