Quantum theory can consistently describe the use of itself in Frauchiger-Renner's Gedankenexperiment

Abstract

Theoretical physics has faced many challenges since the advent of quantum mechanics. Recently, Frauchiger and Renner have presented a no-go theorem, which makes quantum mechanics more controversial. However, from our perspective, the process of proving appears questionable. Therefore, we discuss the validity of their proof approach in this letter. Here, we propose a simple thought experiment that clarifies how correctly the attributed quantum state can be written in problems similar to Frauchiger and Renner's Gedankenexperiment. In the next step, with the help of the correct form of the quantum state, it is demonstrated that a fallacy occurred in the proof of the no-go theorem, which means it cannot be valid because of the wrong proof. Ultimately, getting help from Hardy's paradox, we investigate whether there is an approach to modify their proof in order to lend the no-go theorem validity.

arXiv commentUpon conducting a meticulous evaluation of the aforementioned manuscript in the scholarly publication "Studies in History and Philosophy of Science," it is my scholarly judgment that the methodological approach espoused within the paper is inherently vulnerable to inaccuracies and inconsistencies. Accordingly, I respectfully request that this work be withdrawn
