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

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

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

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