Next, in the scheme for teleportation of an arbitrary multipartite GHZ-class state by one EPR pair, only one EPR pair and 3 classical bits are needed, which greatly lessens the oppressiveness of both quantum and classical channels. Then, in the scheme for deterministic, unilateral and controlled teleportation via cavity QED, Alice can determinately send her state to anyone of her agents, whereas the agents can not, with the channel being noiseless. What the agents can do is just to control the teleporting process, which enhance the security of the communication.Besides,based on the schemes discussed above,it is easy to see the character of an entangled state which can accomplish deterministic teleportation via cavity QED.

利用一个EPR对实现n-体类-GHZ态的量子隐形传态方案，整个通讯过程只需要一个EPR对和3 cbits的经典信息，大大节省了物理资源，缓解信道压力；利用非对称类-W态实现确定的单向受控量子隐形传态，在没有噪声的条件下，Alice可以将量子信息准确无误地发送给任一个客户，但每一个客户只能控制配合整个信息的传输过程，客户之间不能实现确定的信息传递，这样便保证了信息的安全性。
