两个基于四粒子纠缠态的量子秘密共享方案
Two quantum secret sharing scheme based on four-qubit entangled states
摘要
Abstract
Used a four-qubit Cluster state and an asmmetric four-qubit entangled state respectively,this paper proposed two schemes for quantum secret sharing of single-qubit state.The sender of the secret performed Bell-basis measuremented on her particles,and the cooperator operated measurements on his paticles or implemented unitary operators,then the secret receiver could reconstruct the original secret by applying the appropriate unitary operation or controlled-not gate.The analysis shows that any agent can recover secret with the help of the others,so the proposed schemes show more effcient and secure.关键词
