For more than 60 years, Bell's theorem has been the gold standard for demonstrating that quantum mechanics defies the rules of classical physics. Now, an international team of researchers, including ...

Physicists at "B-factories" in the US and Japan are closing in on an abstract diagram called the unitarity triangle in the quest to explain the difference between matter and antimatter. But such ...

Researchers in Germany have moved one step closer to closing the “quantum metrology triangle”, by fabricating a proof-of-principle circuit that links two quantum electrical devices in series, for the ...
