摘要
本注记是对 M. Navascu\'es 声称“所有纠缠态都违反 Leggett 的加密非定域性”[arXiv:1303.5124v2] 的回应。我认为，只有引入进一步限制 Leggett“加密非定域性”概念的额外假设，才能得出该结论。反之，如果仅坚持 Leggett 的原始公理，则存在某些纠缠态，其关联始终与 Leggett 的加密非定域性相容——因此，这是一个真正不同于量子可分性的概念。本注记阐明了这两个概念之间的关系，以及它们与 Bell 的定域因果性假设的关系。

备注
3.5 pages. v2: typo corrected. Published version (titled "Bell's local causality, Leggett's crypto-nonlocality and quantum separability are genuinely different concepts") concentrates on clarifying the differences between these 3 notions, rather than on the claims of arXiv:1303.5124v2 (which has since been updated)
