摘要:

利用量子安全直接通信(QSDC)的思想,提出1个新的基于Bell态的高效量子秘密共享(QSS)方案. 该方案利用量子相干性和1个随机比特串,Alice直接让Bob和Charlie共享其秘密消息,而不是首先与Bob和Charlie建立共享的联合密钥,再用联合密钥传输消息. 1个Bell态可用于共享2?bit的经典信息. 研究表明该方案是安全的.

Abstract:

Drawing idea from the quantum secure direct communication (QSDC), a novel quantum secret sharing (QSS) scheme with high efficiency based on Bell states was proposed. In this scheme, the sender Alice needed no longer share a joint key between her and the two receivers, Bob and Charlie, as well as used the joint key to transmit her message. Alice shared her secret message with Bob and Charlie directly. One Bell state could be used to share two bits message. Investigation showed that the scheme is secure.

Key words: quantum secret sharing, quantum secure direct communication, dense coding, Bell states
