论文摘要
最近的两个著名定理 - “无关观察者无关的事实定理”和“本地友善无关定理”，采用了所谓的扩展的Wigner的朋友场景，以试图对现实的可能性质施加新颖的，非平凡的限制。尽管前者认为没有理论可以将Wigner和他的朋友的结果视为客观，但据说后者比Bell和Kochen-Specker定理更强大。在这里，我对这些定理进行了彻底的分析，并表明它们遭受了质疑其有效性并限制其力量的缺点清单。我得出的结论是，“与观察者无关的事实无关定理”和“本地友好无关定理”未能对物理现实的本质施加重大约束。
Two recent, prominent theorems--the "no-go theorem for observer-independent facts" and the "Local Friendliness no-go theorem"--employ so-called extended Wigner's friend scenarios to try to impose novel, non-trivial constraints on the possible nature of physical reality. While the former is argued to entail that there can be no theory in which the results of Wigner and his friend can both be considered objective, the latter is said to place on reality stronger constraints than the Bell and Kochen-Specker theorems. Here, I conduct a thorough analysis of these theorems and show that they suffer from a list of shortcomings that question their validity and limit their strength. I conclude that the "no-go theorem for observer-independent facts" and the "Local Friendliness no-go theorem" fail to impose significant constraints on the nature of physical reality.
