Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

This interaction could help explain both why quantum processes can occur within environments like the brain and why we lose consciousness under anesthesia.

Physicists are preparing an experiment that sounds like science fiction: a device designed to snare individual particles of ...

When IBM’s pioneering artificial intelligence Watson stumped future Jeopardy! cohost Ken Jennings in primetime in 2011, the machine’s gray matter resided in nearly a hundred super-cooled ...

Add Yahoo as a preferred source to see more of our stories on Google. A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Beyond physics and computer science, understanding quantum computing is now essential for ethical, strategic, and creative leadership in every field.

If a quantum computer can solve a problem that a classical computer cannot, that doesn’t automatically mean the solution will be hard to check. Take, for example, the problem of factoring large ...
