“Spookiness” Confirmed by the First Loophole-free Quantum Test
Spookiness, it seems, is here to stay. Quantum theory has been put to its most stringent “loophole free” test yet, and it has come out victorious, ruling out more common sense views of reality (well, mostly). Many thanks to Matt Leifer for bringing this experiment -- by a collaboration of researchers in the Netherlands, Spain, and the UK -- to my attention. A few years ago, I wrote a feature for Science about the quest to close loopholes in quantum entanglement experiments...
