摘要

在最近的一篇论文中，Cabbolet 认为 PBR 定理是不真实的，因为在量子力学的集合解释中，用于推导 PBR 定理的纠缠测量是不存在的。然而，除了我们已经从PBR定理中知道的纠缠测量的存在与（\psi\）表征模型的存在不相容之外，Cabbolet（1）并没有为纠缠测量的不存在提供任何论证；（2）他也没有说明为什么放弃纠缠测量而不是放弃（\psi\）表征模型更合理。因此，PBR定理仍然完好无损。

PBR, Nonreality and Entangled Measurement

In a recent paper, Cabbolet argues that the PBR theorem is nonreal since in the ensemble interpretation of quantum mechanics the entangled measurement used in the derivation of the PBR theorem is nonexisting. However, Cabbolet (1) does not provide any argument for the nonexistence of entangled measurements beyond the incompatibility of the existence of entangled measurements and the existence of \(\psi\)-epistemic models which we already know from the PBR theorem; and (2) he does not show why it is more reasonable to abandon entangled measurements instead of \(\psi\)-epistemic models. Hence, the PBR theorem remains intact.

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.
