Interstellar space-travel and near-instant communication; discovering a network of intelligent extraterrestrial signals; harnessing the mysterious instantaneous quantum-entanglement effect.
One of the primary science goals of MESSENGER is to study Mercuryâ€™s very thin atmosphere, or exosphere.
A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips.
A team of physicists in the United Kingdom has taken a giant step toward realizing efficient single-photon sources, which are expected to enable much-coveted completely secure optical communications, also known as "quantum cryptography."
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have learned to control the quantum pathways determining how light scatters in graphene.
Northwestern University researchers have developed a new switching device that takes quantum communication to a new level.
Device may help process information and measure motion at quantum scale.
Nanometer-scale gold particles are currently intensively investigated for possible applications in catalysis, sensing, photonics, biolabeling, drug carriers and molecular electronics.
Like snowflakes or fingerprints, no two quantum dots are identical.
The fabric of space-time around spinning black holes should impart a â€œtwistâ€ in the property of light called orbital angular momentum.
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...
