Researchers in Birmingham have created the first image of a photon, a lemon-shaped particle of light emitted from the surface of a nanoparticle. The theory that made this image possible ...

From high-speed communication to quantum computing and sensing, the detection, transmission, and manipulation of light ...

In 1905, Einstein proposed the photon theory of light. According to this, light consists of discrete packets of energy called photons. His work on the photoelectric effect introduced us to wave ...

Data security on the internet is under threat: in the future, quantum computers could decode even encrypted files sent over ...

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. Disclaimer: AAAS and ...

One recent experiment backs up Minkowski's answer — but still may not prove Abraham wrong. One might expect that the momentum of a photon, under almost any conditions, would no longer be a ...
