A cloud of helium atoms split, scattered and fell under gravity, yet still behaved as if its parts were linked. That is the ...

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

In the pursuit of powerful and stable quantum computers, researchers at Chalmers University of Technology, Sweden, have developed the theory for an entirely new quantum system – based on the novel ...

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 ...

Most current models of the Big Bang rely on general relativity along with additional elements that are introduced to make the ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always ...

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 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, ...

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

Physicists in China have simulated the effect of "false vacuum decay": a phenomenon believed to play out constantly in the ...

Other scientists have investigated the idea of a hidden structure further. David Bohm, a 20th-century physicist, built a ...
