Bell's local causality, Leggett's crypto-nonlocality, and quantum separability are genuinely different concepts
Bell's local causality, Leggett's crypto-nonlocality, and quantum separability are genuinely different concepts
This note is a reply to M. Navascu\'es' claim that "all entangled states violate Leggett's crypto-nonlocality" [arXiv:1303.5124v2]. I argue that such a conclusion can only be reached if one introduces additional assumptions that further restrict Leggett's notion of "crypto-nonlocality". If a contrario one sticks only to Leggett's original axioms, there …
