论文摘要
观察者在量子力学中的地位和作用一直是自理论诞生以来一直在进行的辩论的主题。威格纳（Wigner）在著名的场景中提出了这个问题，其中一名超级观察者观察一个朋友进行测量。在这里，我们简要回顾了为何{wigner friends sponario}为何需要引入观察者的意识，或者以表明量子测量理论的不一致。我们将认为，量子理论只能通过对观察者的叙事方式始终如一地将观察者置于其叙事之外，这仅对如何存储有关观察到的结果的信息存储在材料记录中。
The place and role of an Observer in quantum mechanics has been a subject of an ongoing debate since the theory's inception. Wigner brought this question to the fore in a celebrated scenario in which a super-Observer observes a Friend making a measurement. Here we briefly review why this \e{Wigner Friend scenario} has been taken to require the introduction of the Observer's consciousness, or alternatively to show the inconsistency of quantum measurement theory. We will argue that quantum theory can consistently leave observers outside its narrative, by making only minimal assumptions about how the information about the observed results is stored in material records.
