论文摘要
在本文中,通过使用空腔QED中的原子的进化定律提出了通过腔QED的安全量子对话方案。本协议同时采用了两步传输和统一操作编码。采用了两项安全检查,以确保其对外部窃听器的主动攻击的传输安全性。目前的协议通过使用与共享的秘密钟形状态使用任何两个铃铛状态之间的纠缠交换来避免信息泄漏问题。与以前的信息泄漏量量子对话方案相比,本协议在量子测量中利用了优势。
In this paper, a secure quantum dialogue protocol via cavity QED is suggested by using the evolution law of atom in cavity QED. The present protocol employs both the two-step transmission and the unitary operation encoding. Two security checks are adopted to ensure its transmission security against the active attacks from an outside eavesdropper. The present protocol avoids the information leakage problem by using the entanglement swapping between any two Bell states via cavity QED together with the shared secret Bell state. Compared with the previous information leakage resistant quantum dialogue protocol via cavity QED, the present protocol takes advantage in quantum measurement.
