量子密钥分配的通信安全一直是量子信息理论的重要特征之一。不需要建立任何共享密钥的安全直接通信的新概念已成为下一步。提出了一种以三粒子GHZ状态为初始状态的安全通信方案，使接收机可以同时接收来自双方的信息。已经调查了窃听的可能性。
Communication security with quantum key distribution has been one of the important features of quantum information theory. A novel concept of secured direct communication with no need of establishing any shared secret key has been the next step forward. The present paper presents a secured communication scheme with three particle GHZ state as the initial state where the receiver can simultaneously receive information from two parties. Possible eavesdropping has been examined.
