Abstract

Recently, a counter-argument has been presented regarding the invalidity of the Pusey-Barrett-Rudolph (PBR) theorem (Cabbolet, Found. Phys. 53, 64 2023). This claim has sparked a debate, with some authors defending the PBR theorem (Hofer-Szabó, Found. Phys. 54, 36 2024), but the proponent of the claim has insisted on his argument (Cabbolet, Found. Phys. 54, 69 2024; Cabbolet, Found. Phys. 54, 48 2024). Moreover, the author claimed to have proved that the PBR theorem is incorrect by a generic counterexample (Cabbolet, Found. Phys. 54, 48 2024). In this paper, we contribute to the discussion with some new arguments. We demonstrate that the PBR theorem contains no errors and remains intact.

关于PBR定理有效性的讨论

最近，关于普西-巴雷特-鲁道夫（PBR）定理的无效提出了一个相反的论点（Cabbolet, Found）。物理学报，53,64（2023）。这一说法引发了一场争论，一些作者为PBR定理(Hofer-Szabó， Found。物理学，54,36 2024)，但该主张的支持者坚持他的论点(Cabbolet, Found。物理学报54,69 2024；Cabbolet,发现。物理学报，54,48 2024)。此外，作者声称已经通过一个一般的反例证明了PBR定理是不正确的（Cabbolet, Found）。物理学报，54,48 2024)。在本文中，我们提出了一些新的论点。我们证明了PBR定理不包含错误并且保持完整。

期刊介绍： The conceptual foundations of physics have been under constant revision from the outset, and remain so today. Discussion of foundational issues has always been a major source of progress in science, on a par with empirical knowledge and mathematics. Examples include the debates on the nature of space and time involving Newton and later Einstein; on the nature of heat and of energy; on irreversibility and probability due to Boltzmann; on the nature of matter and observation measurement during the early days of quantum theory; on the meaning of renormalisation, and many others. Today, insightful reflection on the conceptual structure utilised in our efforts to understand the physical world is of particular value, given the serious unsolved problems that are likely to demand, once again, modifications of the grammar of our scientific description of the physical world. The quantum properties of gravity, the nature of measurement in quantum mechanics, the primary source of irreversibility, the role of information in physics – all these are examples of questions about which science is still confused and whose solution may well demand more than skilled mathematics and new experiments. Foundations of Physics is a privileged forum for discussing such foundational issues, open to physicists, cosmologists, philosophers and mathematicians. It is devoted to the conceptual bases of the fundamental theories of physics and cosmology, to their logical, methodological, and philosophical premises. The journal welcomes papers on issues such as the foundations of special and general relativity, quantum theory, classical and quantum field theory, quantum gravity, unified theories, thermodynamics, statistical mechanics, cosmology, and similar.
