摘　　要：讨论物理系统在不同的正交态之间演化所需要的时间.首先讨论了两能级系统,随后进一步讨论多能级系统.发现对多能级系统而言,在任意两个正交态之间演化的时间是两能级系统的2倍.这有利于在量子调控时,进行最优化的量子操作.Discussed the time needed for a system that evolves among different orthogonal states.Not only the two energy level system but also the system with many energy levels were discussed.We found that the time needed between any two orthogonal states for the system with many energy levels was double that needed by the system with two energy levels.The results were important for optimal operation on a quantum system.

关 键 词：正交态 最优化 量子操作
