摘要

在最近的一篇论文（Found Phys 54:14, 2024）中，卡尔卡西、奥多弗雷迪和艾达拉得出结论说，哈里根和斯派肯斯定义的（$\psi$-ontic）模型不可能与量子力学一致，因为根据他们的信息论分析，在这两种理论中，非正交态混合物的信息熵是不同的。在本文中，我通过解释量子力学中冯-诺依曼熵的物理起源，论证了这个关于（\psi\）-ontic模型的禁区定理是错误的。

On the Reality of the Quantum State Once Again: A No-Go Theorem for $\psi$-Ontic Models?

In a recent paper (Found Phys 54:14, 2024), Carcassi, Oldofredi and Aidala concluded that the $\psi$-ontic models defined by Harrigan and Spekkens cannot be consistent with quantum mechanics, since the information entropy of a mixture of non-orthogonal states are different in these two theories according to their information theoretic analysis. In this paper, I argue that this no-go theorem for $\psi$-ontic models is false by explaining the physical origin of the von Neumann entropy in quantum mechanics.

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.
