Cracking a decades-old test, researchers bolster case for quantum mechanics
(PHYSorg.com Physics)

In a new study, researchers demonstrate creative tactics to get rid of loopholes that have long confounded tests of quantum mechanics. With their innovative method, the researchers were able to demonstrate quantum interactions between two particles spaced more than 180 meters (590 feet) apart while eliminating the possibility that shared events during the past 11 years affected their interaction.
