Pusey-Barrett-Rudolph定理中的检测效率漏洞

Detection efficiency loophole in Pusey-Barrett-Rudolph theorem

Arijit Dutta, Marcin Pawlowski, Marek Zukowski

摘要:

检测效率漏洞是贝尔不等式实验检验的一个重要问题。最近发现的Pusey-Barrett-Rudolph(PBR)定理也有同样的弱点。本文计算了临界探测效率,在此值以下,PBR对量子态存在论性质的论证是不确定的。这是对最大$ψ$ -认知模型进行的。我们对这个属性有两种不同的定义。给出了临界检测效率最低的最优参与方数目。我们也从相反的方向来处理这个问题。我们提供了一个功能,使我们能够指定哪些认知模型被排除在一个给定的检测效率的实验结果。

英文摘要:

Detection efficiency loophole poses a significant problem for experimental tests of Bell inequalities. Recently discovered Pusey-Barrett-Rudolph (PBR) theorem suffers from the same vulnerability. In this paper we calculate the critical detection efficiency, below which the PBR argument for the ontic nature of quantum state is inconclusive. This is done for the maximally $ψ$-epistemic models. We use two different definitions of this property. The optimal number of parties, for which the critical detection efficiency is the lowest is given. We also approach the problem from the opposite direction. We provide a function which enables us to specify which epistemic models are ruled out by the results of an experiment with a given detection efficiency.
