首先利用非最大（纯）纠缠Greenberger-Horne-Zeibinger（GHZ）态提出了一个可控安全的量子对话协议，然后讨论了实现真实的量子对话的条件.我们证明了在第三方的控制下，经过净化的非最大纠缠GHZ态量子信道，两个授权用户可以无条件安全地同时交换他们的秘密信息.
We present a controlled secure quantum dialogue protocol using a non-maximally (pure) entangled Greenberger–Horne–Zeibinger (GHZ) states at first, and then discuss the requirements for a real quantum dialogue. We show that the authorized two users can exchange their secret messages after purifying the non-maximally entangled GHZ states quantum channel unconditionally securely and simultaneously under the control of a third party.
