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

This publication is essentially a compilation of the lecture notes taken by several people at the introductory course in quantum mechanics given by the authors in conjunction with Los Alamos ...

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, ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

A century ago, science went quantum. To celebrate, physicists are throwing a global, year-long party. In 1925, quantum mechanics, the scientific theory that describes the unintuitive rules of physics ...

Quantum mechanics remains a cornerstone of modern physics, providing a framework for understanding phenomena at the microscopic scale. At the heart of its formulation lies the concept of Hilbert ...

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

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

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 ...

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

The 2025 Nobel Prize in physics has been awarded to a trio of scientists – a Briton, a Frenchman and an American – for their ground-breaking discoveries in the field of quantum mechanics.John Clarke, ...

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 ...
