论文摘要
我们表明，可以通过用包含$ 0 $ s的coset矩阵代替原始的单一散射矩阵来简化多光子干涉测量实验中精心选择的巧合率的总和。这些$ 0 $ s的数量和位置可在不影响原始费率的情况下降低每个项的复杂性。特别是，在某些情况下，证明对持久物的模量平方和平方的总和的评估变成了决定因素的模量平方之和。速率总和显示等于去除干涉仪中的某些光学元素。
We show that sums of carefully chosen coincidence rates in a multiphoton interferometry experiment can be simplified by replacing the original unitary scattering matrix with a coset matrix containing $0$s. The number and placement of these $0$s reduces the complexity of each term in the sum without affecting the original sum of rates. In particular, the evaluation of sums of modulus squared of permanents is shown to turn in some cases into a sum of modulus squared of determinants. The sums of rates are shown to be equivalent to the removal of some optical elements in the interferometer.
