Researchers find a way to close both loopholes in testing entanglement with Bell's inequality

(Phys.org)--A team of researchers working at Delft University in The Netherlands, has perhaps succeeded in closing the two loopholes that have prevented proving that local realism does not hold at the quantum level. They have written a paper detailing their work and have uploaded it to the preprint server arXiv so that others may see it while it undergoes peer review prior to being published in a yet to be announced journal.
