Fidelity and Mutual Entropy in Mixed States for Fermi-resonance Coupling Vibrations of CS₂

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.
