论文摘要
Frauchiger-Renner论点的目的是表明“量子理论不能始终如一地描述自身的使用”：在代理本身受量子实验的许多党派环境中，代理可能会做出与观察相矛盾的预测。在这里，我们仅使用三种代理，与初始量子状态无关，从而消除了任何需要纠缠的必要性，而且不需要调用任何最终测量并导致崩溃。然而，代理商所做的预测和观察结果不能集成到一个一致的帐户中。我们建议，这种\ emph {rashomon效应}的存在，即，不可能团结不同的观点，这是由于未能考虑到\ emph {认知学范围}概念中的任何给定系统的可用信息的限制。
The Frauchiger-Renner argument aims to show that `quantum theory cannot consistently describe the use of itself': in many-party settings where agents are themselves subject to quantum experiments, agents may make predictions that contradict observations. Here, we introduce a simplified setting using only three agents, that is independent of the initial quantum state, thus eliminating in particular any need for entanglement, and furthermore does not need to invoke any final measurement and resulting collapse. Nevertheless, the predictions and observations made by the agents cannot be integrated into a single, consistent account. We propose that the existence of this sort of \emph{Rashomon effect}, i.e. the impossibility of uniting different perspectives, is due to failing to account for the limits put on the information available about any given system as encapsulated in the notion of an \emph{epistemic horizon}.
