纠缠的六粒子的格言联盟者与接收装置作为量隧道说的发送者份额。如果量隧道是安全的,发送者执行射影的大小并且把测量结果告诉接收装置。接收装置执行单一的转变并且在他的粒子上做射影的大小获得秘密信息。用远距传物, three-qubit 秘密信息的传播能在每条量隧道被完成。
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
