摘要
In order to solve the damage problem during remote transmission of quantum signaling, a repeater model of signaling quantum is proposed. In this model, firstly purifying and distributing entanglement of the received signaling quantum state is carried out, to establish entangled channels between the signed sending and receiving. Secondly, through quantum entanglement swapping the quantum signaling is transmitted, for completing the quantum signaling relay. Simulation results show that the success rate of signaling relay can reach more than 97% under the condition that the fidelity is 0.98 and the entangled pairs successful establishing rate is 0.98; the throughput of quantum signaling relay is up to 183 kbps when the probability of entanglement swapping, purification, and entangled pairs successful establishing is 0.98.
