一种新型的可改进的量子秘密共享方案是在A.C.A.Nascimento等人提出的一种改进的量子秘密共享方案(简称IQSS方案)的基础上提出的,新方案较IQSS方案可实现更多的量子存取结构。进一步地,在理论上证明了所有的超星量子存取结构均可由这一新型的量子秘密共享方案实现。作为应用,给出了参与者人数至多为4的所有最优限制量子存取结构共10个,其中9个可以用新方案实现。
A new and improved quantum secret sharing scheme is proposed based on an improved quantum secret sharing scheme proposed by ACANascimento et al. (IQSS scheme for short). The new scheme can realize more quantum storage than the IQSS scheme Take the structure. Further, it is theoretically proved that all the super-quantum access structures can be realized by this new quantum secret sharing scheme. As an application, 10 optimal quantum access structures with a maximum number of participants of 4 are given, of which 9 can be implemented with new schemes.
