基于量子隐形传态的数据链路层停等协议

提出了数据链路层中基于量子隐形传态的量子停等协议，即在数据链路层的2个站点进行通信时，传送量子信息，在设定的时间内，若接收方收到量子帧，则用量子信道来返回确认帧.根据量子隐形传态的瞬时性，该协议减少了2个站点通信的传播时延，从而降低了2个发送成功的量子帧之间的最小时间间隔，缩短了通信时间，提高了通信效率，而且发送方对所传送的量子信息是未知的，从而也提高了信息传输的保密性.

Stop-Wait Protocol of Data Link Layer Based on Quantum Teleportation

The communication protocol of data link layer is studied based on quantum teleportation.When two sites communicate in data link layer，quantum frame is sent via quantum channel.When receiving quantum frame within the set time,the receiver returns to confirm frame via the quantum channel.According to the transient of quantum teleportation,the transmission delay of two sites communication is reduced;as a result,the minimum time span between two successfully delivered quantum frames can be reduced,the communication time is shortened and communication efficiency is improved.And since the sender on the transmission of quantum information is unknown，the confidentiality of information transmission is also increased.
