Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, ...

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

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.

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

The demonstration marks an important step toward practical quantum communication networks. During the experiment, researchers ...

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 ...

The errors that quantum computers make are holding the technology back. But recent progress in quantum error correction has ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

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

One of the biggest promises of quantum computing is the ability to simulate molecules ...

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

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