摘要

The transport properties of the photons injected into one-dimensionalcoupled-cavity-arrays (CCAs) are studied. It is found that the number ofphotons cannot change the evolution cycle of the system and the time points atwhich W states and NOON state are obtained with a relatively higherprobability. Transport dynamics in the CCAs exhibits that entanglement-enhancedstate transmission is more effective phenomenon, and we show that for a quantumstate with the maximum concurrence, it can be transmitted completely withoutconsidering the case of photon loss.
