Optical sensors based on quantum light need to work even in the presence of imperfections. Here we discuss how to address the presence of noise by measuring multiple parameters at once: those we seek to monitor and those linked to the imperfections. Our method is applied to the investigation of the optical activity of sugary solutions limited by reduced visibility. These studies introduce multiparameter estimation as a viable approach to allow for robust operation of quantum sensors as they are developed from fundamental research to technology.

可见度有限的量子相位估计的多参数方法

即使存在缺陷，基于量子光的光学传感器也需要工作。在这里，我们讨论了如何通过一次测量多个参数来解决噪声的存在：我们想要监视的参数以及与缺陷相关的参数。我们的方法适用于对可见度降低的含糖溶液的旋光性的研究。这些研究将多参数估计作为一种可行的方法，使量子传感器在从基础研究发展到技术的过程中就能够稳定运行。
