量子不确定关系是量子力学和经典力学的本质区别，不确定关系分为熵的不确定关系和方差的不确定关系.本文主要回顾了两种类型不确定关系的发展历程，并介绍了不确定关系在量子信息科学中的应用.希望能对今后不确定关系的发展有所帮助.

Quantum uncertainty relations，the foundational difference between classical and quantum mechanics，are divided into variance-based uncertainty relations and entropic uncertainty relations.Here，we mainly review the development of two types of uncertain relationships and introduce the application of uncertainties in quantum information science.We hope that our review is helpful for the future study of the quantum uncertainty.
