Latest Photon Stories
They said it could be done and now theyâ€™ve done it.
The quantum computers of tomorrow might use photons, or particles of light, to move around the data they need to make calculations, but photons are tricky to work with.
CAMBRIDGE, Mass., Dec.
Physicists from the University of Bonn have developed a completely new source of light, a so-called Bose-Einstein condensate consisting of photons.
Researchers at the California Institute of Technology (Caltech) have demonstrated quantum entanglement for a quantum state stored in four spatially distinct atomic memories.
Controlling and modulating the flow of light is essential in today's telecommunications-based society.
Next-Generation Light Source Gets Boost From Powerful New Analysis Technique A new analysis technique for the design and optimization of beam optics has successfully been used to model the group behavior of electron beams over a linear accelerator, paving the way for its use at linear accelerator based light source facilities around the world. Tokyo, Japan (PRWeb UK) November 5, 2010 A new analysis technique for the design and optimization of beam optics has successfully been used to model...
When the military needs to send the key to encrypted data across the world, it can't necessarily rely on today's communication lines, where the message could be covertly intercepted.
Using optically dense, ultra-cold clouds of rubidium atoms, researchers have made advances in three key elements needed for quantum information systems â€“ including a technique for converting photons carrying quantum data to wavelengths that can be transmitted long distances on optical fiber telecom networks.
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...
