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 ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase ...

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

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 ...

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

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When we divide up matter into the smallest possible chunks that it's ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
