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 ...

Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre ...

A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the ...

Scientists have pulled off a mind-bending quantum experiment that sounds almost impossible: they showed that tiny metal ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

Scientists have shown that sunlight alone can generate quantum-correlated photons capable of producing “ghost images,” a feat ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
