Algebraic approach to geometric Quantum Speed Limits in triatomic molecules

Abstract

The appropriate metric of quantum speed limit for the triatomic molecules is discussed using a generalized geometric approach. The researches show the quantum Fisher information metric is tighter than the Wigner-Yanase information metric in realistic molecular dynamical evolution. The quantum speed limit metric is related to the initial evolution state of molecules. PACS: 02.20.Sv, 03.67.-a, 33.15-e
