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.

A groundbreaking experiment at the Tokyo University of Science has proven that beams of antimatter atom exhibit wave-like ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...
