基于团簇态的量子秘密共享方案
Quantum secret sharing scheme based on cluster states
摘要
Abstract
A quantum secret sharing scheme based on cluster states is proposed. The sender encodes the classical secret on cluster states by Pauli operation and the receivers recover secret information by joint measurement. It inserts EPR pairs as decoy states into the sequences of state to prevent eavesdropping. It is showed that this protocol is secure to resist attacks of intercept-measurement, intercept-resend and entanglement-measurement by security analysis. At the same time, one cluster state with four particles can share four bits of classical information, such that qubit efficiency goes to100%.关键词
