Abstract:
states of Fermi-resonance coupling vibrations in molecule CS2. It is demonstrated that those fidelities are dominant-positively correlated with each other, one of which by Wang et al. (Phys. Lett. A 373, 58 (2008)) is the most striking in dominant anti-correlation with quantum mutual entropy. That is useful for molecular quantum computing and quantum information.

CS2费米共振耦合振动混态的保真度和互熵
彭东平,侯喜文*
摘要:
以CS2费米共振耦合振动为例,用混合的相干态和压缩态研究四种保真度动力学,结果表明新近提出的三种保真度是相互正关联的,其中由Wang等提出的保真度(Phys. Lett. A 373,58 (2008))与量子互熵的反关联行
