【摘要】 研究CS₂费米共振耦合振动局域态的Neumann纠缠熵动力学,并研究伸缩与弯曲振动的相互作用能量,目的是建立纠缠与能量的联系.结果表明伸缩振动局域态的纠缠与能量是反关联更明显,而弯曲振动局域态的纠缠与能量是正关联更明显.还讨论了非局域态的纠缠与能量的关系.更多还原

【Abstract】 The dynamics of quantum entanglement described by the von Neumann entropy is studied for the localized states of Fermi-resonance coupling vibrations in molecule CS₂,where the interacting energy between the stretching and the bending modes is considered to establish a connection between entanglement and energy.It is shown that entanglement reveals dominant anti-correlation with the interacting energy for the stretch-localized state,while that exhibits dominantly positive correlation for the bend-localized state.The entanglement and the energy for the dislocahzed states are discussed as well.Those are useful for molecular quantum computing and quantum information in high dimensional states.更多还原
