A new theory that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon. The nature of this interaction ...

Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub. Normally, vortices ...

China’s rapid induction of a mass-produced, ultra-low-noise, four-channel single-photon detector marks a transformative moment in the escalating technological contest between next-generation quantum ...

Controlled generation of single-photon emitters in silicon (red) by broad-beam implantation of ions (blue) through a lithographically defined mask (left) and by a scanned focused ion beam (right).

Alexandru Lupsasca and Michael Johnson won the physics prize for their work on photon spheres — weird rings of light around black holes that may reveal a theory of quantum gravity. When you purchase ...

Researchers have finally proven what it takes to kickstart photosynthesis. Using techniques from the realms of biology and quantum physics, the scientists were able to track photons interacting with ...
