Comment on: Nonlocal Realistic Leggett Models Can be Considered Refuted by the Before-Before Experiment
Marek Zukowski
TL;DR
This paper critiques previous interpretations of Leggett's inequalities and their experimental tests, clarifying assumptions and challenging claims of refutation of nonlocal hidden variable models.
Contribution
It clarifies the assumptions behind Leggett's inequalities and their experimental tests, correcting misrepresentations in prior analyses.
Findings
Suarez's critique of Leggett's assumptions is valid
The modified inequalities used in experiments are based on misrepresented assumptions
Previous experimental refutations of nonlocal hidden variable models are called into question
Abstract
It is shown here that Suarez [Found. Phys. 38, 583 (2008)] wrongly presents the assumptions behind the Leggett's inequalities, and their modified form used by Groeblacher et al. [Nature 446, 871 (2007)] for an experimental falsification of a certain class of non-local hidden variable models.
