摘　　要：为了在多参与者之间实现链式量子通信,采用十量子比特团簇态作为量子信道(quantum channel,QC),提出一种在4方之间进行多量子比特初始态的双向链式受控量子隐形传态(bidirectional-chain controlled quantum teleportation,BCCQT)协议.在通信参与者Alice、Bob、Charlie和通信控制者David之间进行量子通信,并且在量子通信过程中的安全性由控制者的权限和QC的纠缠特性予以保证的情况下,经过多量子比特初始态的复单转换、顺序通信、逆序通信、单重塑和复重塑等一系列复杂的过程和方法来重塑多量子比特初始态,实现了链式量子通信.结果证明该协议是可行的,同时,在此基础上对n+1方量子隐形传态和QC之间的关系提出了猜想.To realize chained quantum communication between multiple actors,a bidirectional-chain controlled quantum teleportation(BCCQT)protocol that provided multi-qubit initial states between four parties was proposed using the ten-qubit cluster state as the quantum channel(QC).Quantum communication was carried out between communication participants Alice,Bob,Charlie and communication controller David,and the security of quantum communication process was guaranteed by the authority of the controller and the entanglement characteristics of QC.After a series of complex processes and methods such as complex single transformation of multi-qubit states,sequential communication,reverse communication,single remodeling and complex remodeling,the initial state of multi-qubit was reconstructed,and the chain quantum communication was finally achieved.Results show that the protocol is feasible.Meanwhile,based on this,a conjecture about the relationship between n+1 square quantum teleportation and QC was proposed.
