Exotic paths: artist's impression of the microwave triple-slot experiment. Courtesy: G Rengaraj et al/New Journal of Physics) The importance of including exotic “non-classical paths” in analyses of ...

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

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

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

Even younger: illustration of the new double-slit experiment using resonant inelastic X-ray scattering on an iridium oxide crystal. An intense beam of high-energy X-ray photons (violet) hits two ...

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in multiple states at once.
