A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

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, ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

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 ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

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 ...

When we look at the world at the tiniest scales, things get very weird. Take a wild ride through the quantum world, from the discoveries that reveal its strange rules to the amazing technologies it ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

The problem with quantum mechanics, or at least the reason even physicists don’t understand it, isn’t that it paints an unfamiliar picture of reality. It isn’t difficult to accept that the world of ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

Regardless of the answers, the era of entanglement under infinite book‐keeping is giving way to an era of entanglement under limited books, limited clocks and limited gates. And in this more realistic ...
