Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

Discover how helium atoms can achieve quantum entanglement, revealing new insights into quantum physics and gravity.

The concept of entanglement links far-flung particles. That relationship can prove that someone is in the location they claim ...

What makes something quantum? This question has kept a small but dedicated fraction of the world’s population – most of them quantum physicists – up at night for decades. At very small scales, we know ...

The results are just what theory predicts, but when the theory clashes as strongly with everyday experience as this, ...

Add Yahoo as a preferred source to see more of our stories on Google. Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless ...

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 ...

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...
