The detection of light at the single-photon level is important for tasks ranging from fluorescence imaging to quantum information processing, reports Neil Savage. High-sensitivity detectors that ...

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. Research at the University ...

Researchers from the University of Birmingham have managed, for the first time, to establish the exact representation of a photon, this particle of light. The discovery, made possible thanks to a new ...

The findings could be useful in fields ranging from quantum computing to renewable energy ... model photon emission in idealized conditions, such as a perfect vacuum with a single atom.

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 532-nm photon alone will either be absorbed at the surface (if its energy is enough to excite the medium) or it will be transmitted through the volume of the medium if it is of less energy.
