Latest Photon Stories
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
Innovation promises better biochemical weapons detection and body scanners, and new instruments for studying dark energy & the structure of the universe.
The storage of light-encoded messages on film and compact disks and as holograms is ubiquitous---grocery scanners, Netflix disks, credit-card images are just a few examples.
Researchers are edging toward the creation of new optical technologies using "nanostructured metamaterials" capable of ultra-efficient transmission of light, with potential applications including advanced solar cells and quantum computing.
Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied.
Quantum technologies promise to redefine the landscape of information processing and communication.
A strong laser beam can remove an electron from an atom – a process which takes place almost instantly.
A team of Chinese physicists have shattered the record for quantum teleportation, teleporting photons approximately six times further than the previous best.
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...
