When sand grains wedge together in a funnel, the whole column locks up. Something strikingly similar can happen to quantum ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

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 ...

A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work ...

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, ...

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades in the making, could help physicists probe the relationship between quantum ...

Quantum key distribution (QKD) has been positioned as a physics-based method of securing encryption keys that cannot be ...

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...
