Understanding the Frauchiger-Renner Argument

Quantum Physics 2020-09-07 v2

Abstract

In 2018, Daniela Frauchiger and Renato Renner published an article in Nature Communications entitled `Quantum theory cannot consistently describe the use of itself.' I clarify the significance of the result and point out a common and persistent misunderstanding of the argument, which has been attacked as flawed from a variety of interpretational perspectives.
