论文摘要
在本文中,我们表明,Harrigan和Spekkens(HS)定义的$ψ$单模型无法再现量子理论。我们没有专注于概率,而是使用信息理论考虑来表明$ψ$单模型的所有纯状态都必须彼此正交,并且明显违反了量子力学。鉴于(i)Pusey,Barrett和Rudolph(PBR)先前表明,HS定义的$ψ$ - 上皮模型也与量子力学相矛盾,并且(ii)HS分类被这两种类型的模型所耗尽,我们得出的结论是,HS分类本身是有问题的,因为它没有对模型的空间,因为模型没有可转换量子的模型。
In this paper we show that $ψ$-ontic models, as defined by Harrigan and Spekkens (HS), cannot reproduce quantum theory. Instead of focusing on probability, we use information theoretic considerations to show that all pure states of $ψ$-ontic models must be orthogonal to each other, in clear violation of quantum mechanics. Given that (i) Pusey, Barrett and Rudolph (PBR) previously showed that $ψ$-epistemic models, as defined by HS, also contradict quantum mechanics, and (ii) the HS categorization is exhausted by these two types of models, we conclude that the HS categorization itself is problematic as it leaves no space for models that can reproduce quantum theory.
