完全实在吗?对 Colbeck 与 Renner 论断的批判性注记

摘要
在一系列论文中,Colbeck 和 Renner 声称已证明量子态为预测未来测量结果提供了完备描述。在本文中,我认为迄今为止尚未给出支持该论断的坚实且令人满意的证明。基于 Leifer、Landsman 和 Leegwater 的早期工作,我提出并证明了仅部分支持该论断的两个结果。随后我讨论了 Colbeck、Renner 和 Leegwater 关于这些结果如何推广至完整论断的论证。该论证转而关键依赖于隐式使用了一个关于幺正演化在量子力学任何可能完备化中应如何表示的假设。我认为该假设不能令人满意,并且试图基于测量理论来验证它的尝试也未能成功。

备注
This version is identical to the published version (modulo a few typos). The typesetting has been altered slightly in comparison to the previous arXiv version to improve readability. This is done because the appendix in the published version is not very readable. In fact, the published version refers to the appendix of this version for the proofs of the theorems
