量子现象统计模型的Pusey-Barrett-Rudolph定理的推广

Generalisations of the recent Pusey-Barrett-Rudolph theorem for statistical models of quantum phenomena

Michael J. W. Hall

摘要:

Pusey,Barrett和Rudolph(PBR)最近给出了一个完全新颖的论点,限制了量子现象的可能模型(arXiv:1111.3328)。在这些注释中,PBR使用的假设被大大削弱,以进一步限制可能的模型类别。PBR使用的“可因式分解”假设被一个弱得多的“相容性”假设所取代,这个假设适用于不相关的量子子系统,而且不需要为每个子系统分配单独的基本属性(即还原论)。此外,它示出的测量独立性的假设可以被丢弃,以获得具有相同的实验意义的相关结果(以较弱的概念意义为代价)。后者是PBR方法的显著特征,因为贝尔不等式、转向不等式和Kochen-Specker定理都需要这种类型的假设。

英文摘要:

Pusey, Barrett and Rudolph (PBR) have recently given a completely novel argument that restricts the class of possible models for quantum phenomena (arXiv:1111.3328). In these notes the assumptions used by PBR are considerably weakened, to further restrict the class of possible models. The `factorisability' assumption used by PBR is replaced by a far weaker `compatibility' assumption for uncorrelated quantum subsystems which, moreover, does not require the assignation of separate underlying properties to each subsystem (i.e, reductionism). Further, it is shown that an assumption of measurement independence may be dropped to obtain a related result having the same experimental significance (at the expense of a weaker conceptual significance). The latter is a remarkable feature of the PBR approach, given that Bell inequalities, steering inequalities and Kochen-Specker theorems all require an assumption of this type.
