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 ...

A rewarding book that offers a cogent look at the science’s history and the second quantum revolution that’s under way ...

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

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

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 ...

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