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

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

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

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

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 ...

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

The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery—and physicists are deeply divided about what is actually going on, a ...

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 ...

Quantum technology has spent more than a century in the lab, but the commercial spark is finally catching. Hardware is maturing, investors are piling in, and early real world deployments are starting ...

In a groundbreaking achievement, researchers at the University of Waterloo have accomplished what quantum researchers believed to be impossible for nearly five decades: the ability to copy quantum ...

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...

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