An Improved Quantum Stop-Wait Communication Protocol

다국어 초록 (Multilingual Abstract)

Based on the delocalized entanglement correlation and transience of transferring quantum information of quantum teleportation, an improved quantum stop-wait communication protocol for data link layer is presented. In the previous quantum stop-wait protocols, they only send the quantum acknowledgement frame (QACK) without sending quantum negative acknowledgement frame (QNACK). In this paper, we present an improved quantum stop-wait communication protocol that sends the negative frame QNACK as soon as possible when Bob detects the error of received data frame, instead of waiting for the retransmission time tout. As a result, the minimum time span between two successfully delivered data frames can be significantly reduced, and the communication time is shortened. It is shown that our protocol enhances the maximum throughput effectively and improves the communication efficiency in the data link layer.
