Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of gravity ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The promise of quantum computing seems ...

Scientists believe that spacetime may have emerged, in part, from a quantum property called “magic.” “Magic” describes how hard a quantum state is to simulate on a regular computer. According to a ...

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 ...

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 ...

Scientists are like prospectors, excavating the natural world seeking gems of knowledge about physical reality. And in the century just past, scientists have dug deep enough to discover that reality’s ...

Quantum mechanics, the theory that describes the physics of the universe at very small scales, is notorious for defying common sense. Consider, for instance, the way that standard interpretations of ...
