发送器与接收器共享六粒子最大纠缠态作为量子通道。如果量子信道是安全的，发送方将执行投影测量并将测量结果告知接收方。接收者执行酉变换并对其粒子进行投影测量以获得秘密信息。利用隐形传态，可以在每个量子通道中完成三个量子比特秘密信息的传输。
The sender shares six-particle maximally entangled states as quantum channel with the receiver. If the quantum channel is secure, the sender performs projective measurements and tells the measurement outcome to the receiver. The receiver performs the unitary transformations and makes projective measurements on his particles to obtain the secret information. Using teleportation, the transmission of three-qubit secret information can be completed in each quantum channel.
