摘要：
Fundamental physical limits on the speed of state evolution in quantum systems exist in the form of the Mandelstam-Tammand the Margolus-Levitin inequalities. We give an expository review of the development of these quantum speed limit (QSL) inequalities, including extensions to different energy statistics and generalizations to mixed system states and open and multipartite systems. The QSLs expressed by these various inequalities have implications for quantum computation, quantum metrology, and control of quantum systems. These connections are surveyed, and some important open questions are noted.
