Model and Simulation of Entanglement Signaling Repeater Network Based on Entanglement Swapping
Aiming at the quantum signalling repeater network model for multi-user, environment quantum noises effect on remote transmission of signalling was studied. A kind of quantum signaling repeater strategy was purposed after the theory of quantum swapping being analyzed. Then a bus network model was put forward and the success rate of long distance quantum signaling transmission was simulated. The results show that long distance signaling transmission has a close relationship with the noise power spectral density, transmission distance and repeater times. When noise power spectral density is constant and there is no repeater during the transmission process, the success rate declines like plesio-flat-parabola with increasing of the transmission distance. On the condition of constant noise power spectral density and constant transmission distance, the success rate increases obviously while the repeater times is increasing. Therefore, on the behalf of reliable quantum signaling transmission the transmission distance and repeater times should be designed properly under the circumstance of constant background noise.
