量子速率极限时间

Quantum speed limit time

系统从初始态演化到目标态所需要的最短时间被定义为量子速率极限时间.此概念可以被用来估量由给定量子态到期望目标态的最大演化速率.本文主要回顾了从封闭系统量子速率极限时间过渡到开放系统量子速率极限时间的发展历程,并讨论了非马尔科夫环境对开放系统量子速率极限时间的影响.希望能对今后量子速率极限时间的发展有所帮助.

The minimum time required for the system to evolve from the initial state to the target state is defined as the quantum speed limit time.This concept can be used to estimate the maximum rate of evolution from a given quantum state to a desired target state.Here,the development of quantum speed limit time from closed system to open system is reviewed,and the influence of non-Markovian environment on the quantum speed limit time of open system is discussed.We hope that our review is helpful for the future study of the quantum speed limit time.
