论文摘要
钻石中的氮 - 视口中心已广泛用于量子传感中，因为它对不同的物理量敏感。同时，在实际应用中，很难将干扰与不良物理量分离。在这里，我们提出了一个强大的基于纤维的量子温度计，该温度计可以显着隔离磁场噪声和微波功率移位。使用频率调制方案，我们通过检测高密度氮气胶合体中零视场光学检测到的磁共振光谱中尖锐浸入的变化来实现温度测量。由于其在磁性和微波噪声中的实现和鲁棒性方面的简单性和兼容性，然后将此量子温度计应用于电子芯片的表面温度成像，其灵敏度为$ 18 $ \ $ \ rm {mk}}/\ sqrt {\ rm rmm {hz}} $。它为模棱两可的环境中的高灵敏温度测量铺平了道路。
The nitrogen-vacancy center in diamond has been broadly applied in quantum sensing since it is sensitive to different physical quantities. Meanwhile, it is difficult to isolate disturbances from unwanted physical quantities in practical applications. Here, we present a robust fiber-based quantum thermometer which can significantly isolate the magnetic field noise and microwave power shift. With a frequency modulation scheme, we realize the temperature measurement by detecting the variation of the sharp-dip in the zero-field optically detected magnetic resonance spectrum in a high-density nitrogen-vacancy ensemble. Thanks to its simplicity and compatibility in implementation and robustness in the isolation of magnetic and microwave noise, this quantum thermometer is then applied to the surface temperature imaging of an electronic chip with a sensitivity of $18$ $\rm{mK}/\sqrt{\rm{Hz}}$. It paves the way to high sensitive temperature measurement in ambiguous environments.
