【摘要】 金刚石中的氮-空位色心（nitrogen-vacancy center,NV center）为室温乃至极端环境（如低温高压）条件下的量子传感技术提供了极具潜力的发展平台。金刚石中的NV色心具有超长的相干时间，在室温下有稳定的光学特性并兼有易读出的特点，因此可以利用光探测磁共振（optical detection magnetic resonance,ODMR）技术进行高精度的探测及量子操控。近二十年来，基于金刚石的量子传感技术的基础研究蓬勃发展，金刚石中的NV色心在如量子精密测量和量子信息处理等科学领域中的应用越来越深入，目前已经实现了在生物化学、凝聚态、温度传感、磁场传感及压力传感等领域的精密测量。本文对基于NV色心的量子传感技术在上述领域中的发展进行了综述。更多还原

【Abstract】 The nitrogen-vacancy(NV) color centers in diamonds provide a remarkable platform for quantum sensing techniques at ambient conditions and high pressure and high temperature. NV centers in diamond have ultralong coherence time, stable optical properties and the fluorescence signal is easy to read out at room temperature, so the optical detection magnetic resonance(ODMR) technique is utilized for high-precision measurement of physical quantities as well as quantum control. By using the coherence of NV centers, we can detect weak signals such as magnetic field, electronic field, pressure, and temperature while obtaining quite high sensitivity and resolution.In the past two decades, the basic research of quantum sensing technology based on the diamond has developed vigorously, NV centers in diamond have been widely used in quantum precision measurement and quantum information processing, heretofore, precise measurements have been achieved in biochemical, condensed matter,temperature, magnetic and pressure sensing field. In this article, we discuss the development and challenges of quantum sensing technology based on NV centers in the above areas.更多还原
