标题： Parameter estimation with efficient photodetectors

摘要： 当前的参数估计技术依赖于亮度较低的光电探测器，因此基于收集平均统计信息。 最近有说法称，完美的光电探测将改变传感算法的本质，并将传感效率提高到超越更大收集效率的直接影响。 在本文中，我们提出观察到完美的光电探测意味着参数估计的海森堡极限（$\frac{1}{T}$）。 我们进行了详细分析的一个具体例子。 显示英文摘要

摘要： Current parameter estimation techniques rely on photodetectors which have low brightness and thus are based on gathering averaged statistics. Recently it was claimed that perfect photodetction will change the nature of sensing algorithms and will increase sensing efficiency beyond the immediate effect of having larger collection efficiency. In this paper we bring up the observation that perfect photodetection implies Heisenberg scaling($\frac{1}{T}$) for parameter estimations. We analyze a specific example in detail.
