Scientists found a way to purify photons and clean light
Light is usually treated as something simple, a clean beam that either shines or does not. At the quantum level, however, ...
Scientists build a new light source for quantum communications by combining existing technologies together to create a stronger and more robust quantum signal. When you purchase through links on our ...
The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...
Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...
