论文摘要
量子波函数的状态是量子基础中最讨论的问题之一 - 它是直接与现实相对应的还是仅代表有关现实某些方面的知识或信息。在这封信中，我们提出了一个{\ it $ψ$ - 内联}定理，该定理排除了一类本体论解释，其中量子波函数仅视为信息。与著名的Pusey-Barrett-Rudolph定理不同，我们的结果并不认为没有用于产品量子制剂的整体本体论特性。在我们推导的核心中，我们利用了约翰·贝尔（John S. Bell）的开创性不进行的结果，它排除了量子理论的任何当地现实世界观。我们表明，观察到的量子非局部性现象不能纳入一类$ψ$ - pepistemic模型中。使用众所周知的clauser-horne-horne-holt不平等现象，我们获得了认识论程度的阈值，在该程度上，本体论模型与量子统计不兼容。
Status of quantum wavefunction is one of the most debated issues in quantum foundations -- whether it corresponds directly to the reality or just represents knowledge or information about some aspect of reality. In this letter we propose a {\it $ψ$-ontology} theorem that excludes a class of ontological explanations where quantum wavefunction is treated as mere information. Our result, unlike the acclaimed Pusey-Barrett-Rudolph's theorem, does not presume the absence of holistic ontological properties for product quantum preparations. At the core of our derivation we utilize the seminal no-go result by John S. Bell that rules out any local realistic world view for quantum theory. We show that the observed phenomenon of quantum nonlocality cannot be incorporated in a class of $ψ$-epistemic models. Using the well known Clauser-Horne-Shimony-Holt inequality we obtain a threshold bound on the degree of epistemicity above which the ontological models are not compatible with quantum statistics.
