19 Aug 2013 | | Abstract: | Two physical principles, Macroscopic Locality (ML) and Information Causality
(IC), so far, have been most successful in distinguishing quantum correlations
from post-quantum correlations. However, there are also some post-quantum
probability distributions which cannot be distinguished with the help of these
principles. Thus, it is interesting to see whether consideration of these two
principles, separately, along with some additional physically plausible
constraints, can explain some interesting quantum features which are otherwise
hard to reproduce. In this paper we show that, in a Bell-CHSH scenario, ML
along with constraint of equal-biasness for the concerned observables, almost
reproduces the quantum joint probability distribution corresponding to maximal
quantum Bell violation, which is unique up to relabeling. In this context, the
known necessary condition that respects IC stands far apart. | | Source: | arXiv, 1308.4003 | | Services: | Forum | Review | PDF | Favorites | |
