Abstract

Abstract: Qubits must be sent again when some qubit errors occur in the data frame in the quantum network between the two communicate sites.Although this repeat guarantees the data accuracy,the pressure of the communication channel is increased.In order to reduce the pressure of the channel and improve the efficiency of selective repeat protocol,the authors analyze the existing selective repeat protocol from the process of quantum states’ replication and teleportation.So the cache of the channel is introduced and the selective repeat protocol of the data link layer is improved.Furthermore,the authors compare the efficiency of protocol and the utilization ratio of channel with previous scheme and provide a reference for seeking more effective and efficient communication means.

Key words: quantum communication, data link layer, protocol, transport efficiency
