AI总结:

本文质疑Frauchiger-Renner不可行定理的证明,提出思想实验阐明量子态正确书写,指出证明谬误,并探讨借助Hardy悖论修正以使其有效。

摘要:

理论物理学自量子力学问世以来面临诸多挑战。近期,Frauchiger和Renner提出了一个不可行定理,使量子力学更具争议性。然而,从我们的视角来看,其证明过程存在可疑之处。因此,我们在本文中讨论其证明方法的有效性。在此,我们提出一个简单的思想实验,阐明在类似Frauchiger-Renner思想实验的问题中,如何正确书写所归属的量子态。下一步,借助量子态的正确形式,我们证明该不可行定理的证明中出现了谬误,这意味着由于证明错误,该定理不能成立。最终,借助Hardy悖论,我们探究是否存在修改其证明以赋予该不可行定理有效性的途径。

英文摘要:

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.
