Latest Photon Stories
Picture two light beams intersecting one another in space.
Researchers from the Niels Bohr Institute have announced the capacity to consistently teleport information between two clouds of gas atoms, according to a report in the journal Nature Physics.
Rice University scientists have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color.
Entanglement, by general consensus of physicists, is the weirdest part of quantum science.
Exchange of electromagnetic energy is fairly well understood. The force carrier, the photon, is readily detectable and manipulated, making the physics of electromagnetic radiation easy to study.
According to a groundbreaking announcement, scientists at Los Alamos National Labs in New Mexico have been utilizing a small-scale “quantum internet” for the past two years.
A team led by the Austrian physicist Anton Zeilinger has now carried out an experiment with photons, in which they have closed an important loophole.
"Spooky action at a distance" is how Albert Einstein rather famously described the theory of quantum entanglement. Until now, however, experiments attempting to examine this peculiar quantum mechanical phenomenon have been limited to relatively small distances on Earth.
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...
