Abstract

Considering a complicated extension of a Wigner's friend scenario, Frauchiger and Renner (FR) allegedly showed that “quantum theory cannot consistently describe the use of itself.” However, such a result has been under severe criticism, as it has been convincingly argued to crucially depend on an implicit, non-trivial assumption regarding details of the collapse mechanism. In consequence, the result is not as robust or general as intended. On top of all this, in this work we show that a much simpler arrangement—basically an EPR setting—is sufficient to derive a result fully analogous to that of FR. Moreover, we claim that all lessons learned from FR's result are essentially contained within the original EPR paper. We conclude that FR's result does not offer any novel insights into the conceptual problems of quantum theory.

维格纳那些令人费解的朋友

考虑到维格纳的朋友场景的复杂扩展，弗劳希格和雷纳(FR)据称表明，“量子理论不能始终如一地描述自身的使用。”然而，这样的结果受到了严厉的批评，因为它令人信服地认为，它关键地依赖于一个隐含的、关于坍缩机制细节的非平凡假设。因此，结果不像预期的那样健壮或通用。最重要的是，在这项工作中，我们证明了一个更简单的安排——基本上是一个EPR设置——足以得出一个完全类似于FR的结果。此外，我们声称，从FR的结果中吸取的所有教训基本上都包含在原始的EPR论文中。我们得出结论，FR的结果并没有为量子理论的概念问题提供任何新颖的见解。

期刊介绍： Studies in History and Philosophy of Modern Physics is devoted to all aspects of the history and philosophy of modern physics broadly understood, including physical aspects of astronomy, chemistry and other non-biological sciences. The primary focus is on physics from the mid/late-nineteenth century to the present, the period of emergence of the kind of theoretical physics that has come to dominate the exact sciences in the twentieth century. The journal is internationally oriented with contributions from a wide range of perspectives. In addition to purely historical or philosophical papers, the editors particularly encourage papers that combine these two disciplines. The editors are also keen to publish papers of interest to physicists, as well as specialists in history and philosophy of physics.
