论文摘要
自从量子力学出现以来，理论物理学已经面临许多挑战。最近，Frauchiger和Renner提出了一个无关定理，这使量子力学更具争议性。但是，从我们的角度来看，证明的过程似乎值得怀疑。因此，我们在这封信中讨论了他们证明方法的有效性。在这里，我们提出了一个简单的思想实验，阐明了可以用类似于Frauchiger和Renner的Gedankenexperiment的问题编写的量子状态。在下一步中，借助量子状态的正确形式，证明了谬论发生在无关定理的证明中，这意味着由于错误的证明，它是无效的。最终，从Hardy的悖论中获得帮助，我们研究是否有一种修改其证据的方法以借出无关定理的有效性。
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.
