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, ...

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 ...

Jacob A. Barandes is a senior preceptor in physics and associated faculty in philosophy. This interview has been edited for length and clarity. FM: You’re from New York, and you’ve since moved to ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

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 theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

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

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 ...

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