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

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

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

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

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

Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...

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

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