摘    要:在集体噪声条件下提出三个带身份认证的量子对话协议,两个量子对话协议分别用于抵抗集体消相干噪声和集体旋转噪声,另一个用于同时抵抗这两种集体噪声.通信双方通过广义幺正变换将自己的秘密信息编码到量子态中;并根据自己的秘密信息和携带秘密信息的粒子的初末两量子态,便可推知对方的秘密信息实现量子对话.协议的效率、安全性和无信息泄露等性能分析表明了协议的有效性.

关 键 词:集体噪声  身份认证  量子对话  无信息泄露

Abstract:Three quantum dialogue protocols with identification are proposed under the condition of collection noise. They are used to resist collective-dephasing noise, collective-rotation noise and both collective noises respectively. The two communication parties encode their own secret information into the quantum states with the generalized unitary transformation. Each communication party can deduce the secret message of his counterpart according to his secret message and the two quantum states (one is quantum state before being encoded, and the other is quantum state after being encoded), to achieve a quantum dialogue. It is important that our protocols all should be able to resist various attacks, such as disturbance attack, Trojan horse attack, intercept-resend attack and entanglement measure attack. Moreover, the efficiency and the information leakage of the proposed protocol are analyzed in detail.
