Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

Above is a video by the physicist, YouTuber and quantum cartographer Dominic Walliman, who describes a map of quantum physics that he has created. The map introduces quantum mechanics by providing ...

Electrons are elementary particles -- indivisible, unbreakable. But new research suggests the electron's quantum state -- the electron wave function -- can be separated into many parts. That has some ...

The heart of quantum mechanics is the wave-particle duality: matter and light possess both wave-like and particle-like attributes. Typically, the wave-like properties are inferred indirectly from the ...
