摘要：

关系量子力学（RQM）是对量子力学的一种解释，其基础是量子态不是描述系统的绝对属性，而是描述系统之间的关系。在这篇文章中，我们观察到，有一个紧张关系RQM的自然强调的物理信息和某些种类的信息在目前的配方RQM的不可访问性。因此，我们提出了一个新的假设RQM，它要求所有的信息所拥有的某个观察者被存储在该观察者的物理变量，从而通过测量访问其他观察者，所以观察者可以达到相互主观的协议，在过去发生的量子事件。基于这一假设，我们提出了一个本体论的RQM坚持的原则，量子态总是关系，但也假定了一组量子事件是不严格的关系。我们表明，新的假设有助于解决一些现有的反对RQM，最后我们解决的Frauchiger-Renner实验的背景下，RQM。

英文摘要：

Relational quantum mechanics (RQM) is an interpretation of quantum mechanics based on the idea that quantum states describe not an absolute property of a system but rather a relationship between systems. In this article, we observe that there is a tension between RQM's naturalistic emphasis on the physicality of information and the inaccessibility of certain sorts of information in current formulations of RQM. Therefore we propose a new postulate for RQM which requires that all of the information possessed by a certain observer is stored in physical variables of that observer and thus accessible by measurement to other observers, so observers can reach intersubjective agreement about quantum events which have occurred in the past. Based on this postulate, we suggest an ontology for RQM which upholds the principle that quantum states are always relational, but which also postulates a set of quantum events which are not strictly relational. We show that the new postulate helps address some existing objections to RQM and finally we address the Frauchiger-Renner experiment in the context of RQM.
