Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...

Physicists in Japan have, for the first time, observed quantum interference in a beam of positronium — a short-lived atom made of an electron and its antimatter twin, the positron. The experiment ...

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