依赖光学读出场的传感和计量平台中的最小可分辨信号越来越受到标准量子极限的限制，该极限由光子散粒噪声和反作用噪声之和决定。反作用和散粒噪声降低技术的结合对于开发下一代传感器至关重要，这些传感器适用于从高能物理到生物化学的应用，以及能够解析以前被量子噪声掩盖的材料特性的新型显微镜平台。本视角回顾了近年来使用压缩光进行亚散粒噪声量子传感所取得的巨大进展，并重点介绍了新兴应用，这些应用使基于信号的新科学成为可能，否则这些信号将被标准量子极限的噪声所掩盖。
The minimum resolvable signal in sensing and metrology platforms that rely on optical readout fields is increasingly constrained by the standard quantum limit, which is determined by the sum of photon shot noise and back-action noise. A combination of back-action and shot noise reduction techniques will be critical to the development of the next generation of sensors for applications ranging from high-energy physics to biochemistry and for novel microscopy platforms capable of resolving material properties that were previously obscured by quantum noise. This Perspective reviews the dramatic advances made in the use of squeezed light for sub-shot-noise quantum sensing in recent years and highlights emerging applications that enable new science based on signals that would otherwise be obscured by noise at the standard quantum limit.
