对Rowe 2001探测器效率实验的评论

Critique of the Rowe 2001 Detector Efficiency Experiment

Douglas G. Danforth

摘要:

Rowe 2001实验从两个制备的9 Be+离子散射光子。散射光子的测量使用单个光电倍增管(PMT)。所得直方图似乎是单个离子分布的叠加,但这是不正确的。PMT记录离子的联合概率密度的卷积。有许多不同的关节密度产生相同的PMT直方图。每种密度都有不同的相关性。对于固定的PMT直方图,这些相关性的范围可以很大,例如-0.730到+0.997。报告的相关性的基础上的水平和类别的“零亮”,“一亮”,和“两亮”是不支持的。因此,声称检测效率漏洞已被关闭是无效的。对于这个实验,检测漏洞仍然是开放的。

英文摘要:

The Rowe 2001 experiment scattered photons from two prepared 9Be+ ions. Measurement of the scattered photons used a single photomultiplier tube (PMT). The resultant histograms appear to be a superposition of the individual ions' distribution, but that is not correct. The PMT records the convolution of the joint probability density of the ions. There are many different joint densities which yield the same PMT histograms. Each density has a different correlation. For a fixed PMT histogram the range of those correlations can be large, e.g. -0.730 to +0.997. The reported correlations based on discriminator levels and the categories 'zero bright', 'one bright', and 'two bright' are unsupported. As such the claim that the detection efficiency loophole is closed is invalid. For this experiment, the detection loophole remains open.
