Test of the no-signaling principle in the Hensen "loophole-free CHSH experiment"

Abstract

We analyze the data from the loophole-free CHSH experiment performed by Hensen et al., and show that it is actually not exempt of an important loophole. By increasing the size of the sample of event-ready detections, one can exhibit in the experimental data a violation of the no-signaling principle with a statistical significance at least similar to that of the reported violation of the CHSH inequality, if not stronger.

This version was updated on the basis of our talk at the conference "Quantum and Beyond", Växjö, Sweden, June 2016, and a few emails received from the readers of the first version of this arXiv, we improved statistical analysis and clarified essentially our point
