Loophole-free Bell violations

The most profound discovery of science appears to be confirmed with essentially no wiggle room. The group led by Ronald Hanson at the Delft University of Technology in the Netherlands claim to have reported a loophole-free observation of Bell violations. Links:

I hope Matt Leifer is right and they give a Nobel Prize for this work.

EDIT Nov 12: Two other groups, who were clearly in a very close race, have just posted their loophole-free experiments: arXiv:1511.03189 and arXiv:1511.03190. (H/t Peter Morgan. Also, note the sequential numbers.) Delft’s group published as soon as they had sufficient statistics to reasonably exclude local realism, but the two runner-ups have collected gratifyingly larger samples, so their p-values are more like 1 in 10 million.
