Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

Researchers at Tokyo University of Science have, for the first time, observed quantum interference in a beam of positronium — an exotic atom made of an electron and its antimatter twin, the positron.

An intense X-ray beam (in pink) is focused into a small spot on a single nanoscale grain of a platinum electrode (highlighted within the droplet). Diffraction interference patterns from that grain ...
