我们认为，分析计划的计量仅仅在平均粒子数可以掩盖粒子的数量有效地用于信息事件。对于一些国家，我们证明，在频率论和贝叶斯框架，状态的平均数基本上可以解耦的方面的总人数分布与任何其他优势。
We argue that analysing schemes for metrology solely in terms of the average particle number can obscure the number of particles effectively used in informative events. For a number of states we demonstrate that, in both frequentist and Bayesian frameworks, the average number of a state can essentially be decoupled from the aspects of the total number distribution associated with any metrological advantage.
