An Enormous Test of Bell’s Inequalities

Nicolas Gisin (and colleagues) have executed an enormous test of the Bell-inequalities! Their experiment will span laboratories in the cities of Geneva, Satigny, and Jussy.

I believe that makes it the largest Bell-experiment ever done — the idea being that gravitational effects might have some influence on the measurement problem when there’s a lot of spacelike separation. Gisin first mentioned this idea to us at the New Directions conference in April, which I wrote about before.

And just so that you’re not in suspense: the Bell inequalities were violated, as usual. Read the paper here.
