摘要
为了实现可靠的、远距离的量子安全通信,提出一种高效的具有自避错传输的量子中继器网络方案。方案中,基于中继器的量子网络利用每个中继器之间进行Con^A_C→D和Rem_B→D操作,最终使得目地中继器和源中继器之间建立Bell态的量子信道,传输的安全性也由Bell态的纠缠特性保证。为了提高量子中继器的抗噪声功能,利用了单光子态自避错传输技术设计了具有避错传输功能的由各种光学元器件组成的量子中继器,利用光子传输的时间差纠正错误,有效地避免了联合噪声对传输信息的影响,使得其他的量子中继器可以顺利恢复出未知信息,大大提高了量子态传输的可靠性。
In order to achieve reliable, long-range quantum secure communication, we propose a safe and efficient quantum repeater network scheme with the function of self-avoiding transmission. The quantum repeater network in the scheme operates Conc→D and RemB→D between each node. Finally, the Bell state is shared between the destination node and the source node as a quantum channel after above operation. The security of the transmission is ensured by the entanglement of the Bell state. In the transmission process,in order to improve the anti-noise function of the quantum repeater,we design a quantum re- peater with the avoidance transmission function based on the role of optics. The repeater, consisting of a variety of non-ideal optical components, make full use of photon transmission time difference between different opticals to correct the error. The quantum repeater with this design can effectively and afely a- void the joint noise effects on the transmission of information,which make the other quantum repeater successfully restore the unknown information that it is disturbed by noise. At the same time, the quan- tum repeater network scheme greatly improves the reliability of quantum state transmission.
