As an important concept in fundamental physics, quantum speed limits (QSLs) impose lower bounds on the evolution time required for a quantum system to evolve between two distinguishable states,[1] and the time–energy uncertainty principle is one of its possible physical interpretations.[2] QSL plays an important role in quantum information processing, which could be used to infer the maximal rate of information transfer,[3,4] analyze the scrambling of information,[5] improve measurement precision in quantum metrology,[6–8] estimate computational capacity,[9,10] explore quantum optimal control,[11–17] investigate entropy production rate in nonequilibrium quantum processes,[18,19] enhance the charging power of quantum batteries,[20–22] and so on.翻译并解释

量子速度极限(Quantum Speed Limits,QSLs)是量子物理学中一个重要的概念,它对量子系统从一个可区分状态演化到另一个可区分状态所需的时间施加了下限。时间-能量不确定性原理是它的一种可能的物理解释。QSL在量子信息处理中扮演着重要的角色,可用于推断最大信息传输速率,分析信息的混沌,提高量子计量学中的测量精度,估计计算能力,探索量子最优控制,研究非平衡量子过程中的熵产生速率,增强量子电池的充电能力等等。
