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

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

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 ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls ...

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behaviour – in conflict with our everyday ...
