Toshiba touts Quantum Key Distribution
Blog Current QKD systems are limited by the semiconductor devices (avalanche photodiodes) used to detect the single photons. Quantum Key Distribution -- ] QKD -- relies on sending encoded single photons (particles of light) along the fibre.

Researchers, literally, catch some rays
News The light, composed of particles called photons, essentially lost its zing as the information from the photons was transferred into the spin inherent in the gas atoms. Both MIT and Caltech are trying to build communication applications based on...

It's not just the LHC that could rewrite physics
Blog Radiation happens when a nucleus's component parts - neutrons and protons - are tipped from one stable relationship to another at lower energy, resulting in the expulsion of the spare energy as mass or photons.
