Hardy's paradox, created in 1992, hinted at a scenario haunting the edges of quantum physics. It presented a thought ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

Quantum theory – our best understanding of the world at the smallest level – is famously weird and notoriously confusing. It’s a theory that seems to say particles can be in two places at once, or ...

Unless you're a physicist, you've probably only encountered quantum mechanics on TV. And even when it was explained, you might've still been a little confused. The field of quantum mechanics was ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Long considered a serious technical challenge, superradiance could actually help quantum devices go even further.

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...
