基于局域区分的新的量子秘密共享方案

摘要

Rahaman proposed a quantum secret sharing scheme based on local distinguishability.In check phase,participants make local measurements using special X(Y)-basis to distinguish the orthogonal states so as to detect the eavesdropping.In order to obtain a more general scheme,this paper extended the special basis to a general one.Then it proposed a new (n,n) threshold quantum secret sharing scheme by means of the general basis.The new scheme is more general in theory.Furthermore,it discussed the security of the scheme.%Rahaman提出了一种基于局域区分的量子秘密共享方案.在检测阶段,参与者使用特殊的X(y)基进行局域测量,用来区分这对正交态,从而检测窃听.为了得到更为一般的方案,特将特殊基推广为一般基,并利用一般基得到了一种新的(n,n)门限量子秘密共享方案.与原方案相比,新方案在理论上更具一般性.最后讨论了新方案的安全性.
