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 ...

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 ...

World Quantum Day is more than a celebration of science. It marks a significant step forward in understanding a technology ...

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 ...

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 ...

The quantum layer will will not be exhausted by one hardware modality, one algorithmic framework or one vendor’s roadmap.

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