【摘要】 为提高协议在实验中的可操作性,提出了一个利用二粒子最大纠缠Bell态的量子秘密共享协议,其中发送方利用随机插入的正交单量子位,不仅可以有效地检测窃听行为,而且可以减少用于检测安全性的纠缠粒子,进而提高了纠缠粒子的利用率及产生密钥的效率;而接收方Bob和Charlie必须执行联合测量才能获得密钥,单独一方无法获得秘密信息.更多还原

【Abstract】 In order to enhance maneuverability of the protocol in the experiment,aprotocol of quantum secret sharing based on the four Bell states is proposed.In the protocol,using the orthonormal single qubits and randomly interting them to two sequences,the sender not only find the listener-in effectively,but also decrease the number of entangled particles,which improves the efficiency in use of entangled particles and the efficiency of producing the secret key;the receivers,both Bob and Charlie must perform the Bell basis measurement to obtain the secret,but either of them cannot.更多还原
