摘要
我们研究两耦合非线性振子模型的量子纠缠和量子相干动力学,结果表明在适当条件下,纠缠熵与相干度是正相关的.我们也讨论纠缠熵和相干度与两振子相互作用能的联系.
The dynamics of quantum entanglement and coherence is studied for two coupled nonlinear oscillators.The results show that entanglement and coherence are dominantly positive correlated for a suitable condition.The relationship among quantum entanglement,quantum coherence,and the interacting energy between two oscillators is discussed as well.
