本文针对一篇研究极化超子-反超子系统量子资源的工作展开评论，指出其物理解释缺乏依据、存在技术与概念问题，呼吁修正其结论并厘清唯象建模与物理机制的区别。
AI 中文摘要
本文针对近期发表的工作[Eur. Phys. J. C 86, 988 (2026)]展开评论，该工作利用带记忆的关联退相通道研究极化超子-反超子系统中的量子资源。尽管利用实验重建的自旋密度矩阵表征超子产生过程中的量子关联或许是合理的研究动机，但本文认为，将超子-反超子对视为经历关联环境退相干的开放量子系统这一解释缺乏物理依据：未识别出支撑所假设关联退相通道的物理环境或系统-环境相互作用，且强子化过程无法简单解读为这类环境退相过程。因此，该工作声称的非马尔可夫性、信息回流及记忆辅助的量子资源保护，应被视为唯象通道的属性，而非超子-反超子产生过程中已确立的物理效应。本文还指出了该工作在退相动力学、纠缠量化、相干性的基矢依赖性及量子资源层级声称等方面的若干技术与概念问题，这些问题要求对该工作的物理解释和定量结论进行重大修正。希望本文的评论有助于厘清高能粒子系统中唯象量子通道建模与已确立的物理动力学机制的区别，为未来研究提供有益指导并避免类似概念与技术问题。
英文摘要
We comment on the recent work [Eur. Phys. J. C 86, 988 (2026)], which investigates quantum resources in polarized hyperon--antihyperon systems using correlated dephasing channels with memory. Although the use of experimentally reconstructed spin-density matrices to characterize quantum correlations in hyperon production may be a good motivation, we argue that the interpretation of the hyperon--antihyperon pair as an open quantum system undergoing correlated environmental decoherence is not physically established. In particular, no physical environment or system--environment interaction responsible for the assumed correlated dephasing channel is identified, and hadronization cannot simply be interpreted as such an environmental dephasing process. Consequently, the claimed non-Markovianity, information backflow, and memory-assisted protection of quantum resources should be regarded as properties of a phenomenological channel rather than established physical effects in hyperon--antihyperon production. We also identify several technical and conceptual issues concerning the dephasing dynamics, entanglement quantification, basis dependence of coherence, and the claimed hierarchy of quantum resources. These issues call for a substantial revision of the physical interpretation and quantitative conclusions of the work. We hope that the present Comment will help clarify the distinction between phenomenological quantum-channel modeling and physically established dynamical mechanisms in high-energy particle systems, and thereby provide useful guidance for future studies and help avoid similar conceptual and technical issues.
