Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By ...

Quantum communication promises many advantages over today's standard technologies, including absolutely secure transmission ...

New research shows that cutting a single particle of light spawns photons all the way to infinity.

A photon is a single particle of light, and under normal circumstances, it can’t be divided. But a photon is also not a particle, in the sense that it does not have a specific location. Instead, it is ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

Forbes contributors publish independent expert analyses and insights. I write about biodiversity and the hidden quirks of the natural world. Research reveals how close human vision comes to sensing ...

Nearly a century after Italian physicist Ettore Majorana laid the groundwork for the discovery that electrons could be divided into halves, researchers predict that split photons may also exist, ...
