Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

A cluster of 7,000 sodium atoms has just been coaxed into behaving as a single, ghostly wave, stretching quantum weirdness into a realm that starts to look uncomfortably like everyday matter. Instead ...

It may sound like an oxymoron, but this massive nanoparticle made up of 7,000 sodium atoms is the largest to exhibit such ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a stringent test of quantum mechanics. Matter wave in the spotlight: The image ...

Athought experiment at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally ...
