Abstract
In this paper we study the quantum selective repeat protocol of data link layer based on quantum teleportation. When two sites are communicating in the physical layer, the sender divides a series of qubits intom frames by adding auxiliary qubits. After continuously transmitting m quantum frames, the receiver judges whether he receives the correct quantum frame according to the classical information provided by the sender. If the receiver receives the correct quantum frames, he returns confirmed frames using the quantum channel. If the correct quantum frames are not received, the receiver does not return denial frames. The sender judges quantum frames which he must resend according to the received confirm frames in setting time. Because the sender resends only the quantum frames which are lost or mistaken, this protocol reduces the transmission delay and improves communication efficiency. In the entire course of communications, the classical channel is used only to transmit the survey information, thus its burden is reduced.
