Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

According to a new theory, our universe developed from a “pre-inflationary multiverse” made of particles in quantum superposition.

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one.

The investigation into quantum mechanics and identity in physics explores the profound implications of particle indistinguishability and the emergence of distinct identities from fundamentally ...

Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly ...

Add Yahoo as a preferred source to see more of our stories on Google. Two Physical Review A papers outline how anyons could exist in one dimension, and how cold-atom experiments might spot them.

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

Scientists built a quantum gate linking four-state photons, showing complex quantum tasks can be done with fewer steps using qudits.

Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...
