Abstract

Abstract: 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.

Key words: quantum uncertainty relation, entropy, variance, quantum information
