In a recent result, Frauchiger & Renner argue that if quantum theory accurately describes complex systems like observers who perform measurements, then “we are forced to give up the view that there is one single reality.” Following a review of the Frauchiger-Renner argument, I argue that quantum mechanics should be understood probabilistically, as a new sort of non-Boolean probability theory, rather than representationally, as a theory about the elementary constituents of the physical world and how these elements evolve dynamically over time. I show that this way of understanding quantum mechanics is not in conflict with a consistent “single-world” interpretation of the theory.

在最近的结果中，Frauchiger＆Renner认为，如果量子理论准确地描述了诸如执行测量的观察者之类的复杂系统，那么“我们被迫放弃存在单一现实的观点。” 继Frauchiger -伦纳论证的审查，我认为，量子力学应该理解概率，作为一个新的排序非布尔概率论的，而不是表象，作为一个对物理世界的基本成分和如何将这些元素理论随着时间的推移动态变化。我表明，这种理解量子力学的方式与理论的一致“单世界”解释没有冲突。
