Latest Photon Stories
Two physicists, one from the United States and one from France, were revealed on Tuesday October 9, 2012 as winners of the Nobel Prize in Physics.
Since 1927, when Werner Heisenberg formulated the uncertainty principle, it has stood as one of the cornerstones of quantum mechanics. It has also driven quantum physicists crazy for nearly a century.
An international team of researchers has achieved quantum teleportation over a record distance of 143 kilometers. The experiment marks a major step towards satellite-based quantum communication.
Berkeley Lab scientists and their colleagues have successfully probed the effects of light at the atomic scale by mixing x-ray and optical light waves at the Linac Coherent Light Source
Scientists have long believed that spacetime is foamy, like a freshly pulled draft beer, but new information from an intergalactic photo finish shows it might just be as smooth as a single malt whiskey, instead.
Berkeley Lab and UC Berkeley researchers record first direct observations of quantum effects in an optomechanical system
Single particles of light, also known as photons, have been produced and implemented into a quantum key distribution (QKD) link, paving the way for unbreakable communication networks.
Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography and quantum computing.
At the Vienna University of Technology, a very special kind of bright coherent x-ray radiation has been created by an international team of scientists; the new method was presented in the current issue of Science
Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
