论文摘要
关系量子力学（RQM）声称是量子理论的一种解释[请参见Arxiv：2109.09170，它出现在《量子物理学解释史》手册中。 However, there are significant departures from quantum theory: (i) in RQM measurement outcomes arise from interactions which entangle a system $S$ and an observer $A$ without decoherence, and (ii) such an outcome is a "fact" relative to the observer $A$, but it is not a fact relative to another observer $B$ who has not interacted with $S$ or $A$ during the foregoing measurement process.对于$ b $，系统$ s \ otimes a $仍然纠缠。我们得出一个类似GHz的矛盾，表明这些陈述描述的相对事实与量子理论不相容。因此，根据我们引入的解释标准，关系量子力学不应被视为量子理论的解释。该标准指出，每当解释引入结果的概念时，这些结果，无论它们是什么，都必须遵循诞生规则指定的概率分布。
Relational Quantum Mechanics (RQM) claims to be an interpretation of quantum theory [see arXiv:2109.09170, which appears in the Oxford Handbook of the History of Interpretation of Quantum Physics]. However, there are significant departures from quantum theory: (i) in RQM measurement outcomes arise from interactions which entangle a system $S$ and an observer $A$ without decoherence, and (ii) such an outcome is a "fact" relative to the observer $A$, but it is not a fact relative to another observer $B$ who has not interacted with $S$ or $A$ during the foregoing measurement process. For $B$ the system $S \otimes A$ remains entangled. We derive a GHZ-like contradiction showing that relative facts described by these statements are incompatible with quantum theory. Hence Relational Quantum Mechanics should not be considered an interpretation of quantum theory, according to a criterion for interpretations that we have introduced. The criterion states that whenever an interpretation introduces a notion of outcomes, these outcomes, whatever they are, must follow the probability distribution specified by the Born rule.
