摘　　要：极低温、高压强、强磁场等极端条件是发现和调控新奇物态的重要途径.为了能在极端条件下实现灵敏的物性测量,需要发展先进的传感探测方案.基于金刚石氮空位中心的自旋量子传感可实现磁学、电学、力学、热学等物理参数的灵敏测量,而且拥有微纳尺度的空间分辨率和极其宽泛的工作区间,有望成为极端条件下灵敏物性测量的重要工具.本文主要介绍低温、高温、零场、强磁场以及高压强等极端条件下金刚石氮空位中心的光学性质和自旋相干性质,探讨极端条件下金刚石自旋量子传感所面临的机遇和挑战.本文也包含自旋量子传感的基础知识和极端条件下量子传感应用进展.Extreme conditions,such as ultra-low temperatures,high pressures,and strong magnetic fields,are critical to producing and studying exotic states of matter.To measure physical properties under extreme conditions,the advanced sensing schemes are required.As a promising quantum sensor,the diamond nitrogen-vacancy(NV)center can detect magnetic field,electronic field,pressure,and temperature with high sensitivity.Considering its nanoscale spatial resolution and ultra-wide working range,the diamond quantum sensing can play an important role in frontier studies involving extreme conditions.This paper reviews the spin and optical properties of diamond NV center under extreme conditions,including low temperature,high temperature,zero field,strong magnetic fields,and high pressures.The opportunities and challenges of diamond quantum sensing under extreme conditions are discussed.The basic knowledge of spin-based quantum sensing and its applications under extreme conditions are also covered.
