For decades, entanglement has been the hallmark of quantum weirdness, a ghostly connection between particles that Einstein famously called "spooky action at a distance." It is at the heart of quantum ...
In the early 1960s the physicist John Bell dreamt up one of the most profound experimental tests ever imagined. While on sabbatical in the US on leave from CERN, he had been contemplating the ...
Researchers at ETH Zurich say they have succeeding in demonstrating that quantum mechanical objects that are far apart can be much more strongly correlated with each other than is possible in ...
A group of researchers led by Andreas Wallraff, Professor of Solid State Physics at ETH Zurich, has performed a loophole-free Bell test to disprove the concept of “local causality” formulated by ...
