2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/169778I make some critical comments on the article "An experimental test of non-local realism", by S. Groblacher, T. Paterek, R. Kaltenbaek, C. Brukner, M. Zukowski, M. Aspelmeyer, & A. Zeilinger, Nature 446, p. 871-875 (2007). This article makes incorrect claims concerning Bell's theorem. Moreover, I point to the fact that a hypothesis referred to as "realism" in the article (Groblacher et al.) is not used in the deduction of Leggett's inequality.6 pages, 16 references, no figuresQuantum Physicstext
