World’s First Photonic Router
2014-07-14 03:14:29

Weizmann Institute of Science Weizmann Institute scientists take another step down the long road toward quantum computers Weizmann Institute scientists have demonstrated for the first time a photonic router – a quantum device based on a single atom that enables routing of single photons by single photons. This achievement, as reported in Science magazine, is another step toward overcoming the difficulties in building quantum computers. At the core of the device is an atom that can...

Measuring A Quantum System Using 'Compressive Sensing'
2014-06-30 03:59:48

Leonor Sierra, University of Rochester Researchers show momentum and position of quantum system can be determined using technique from signal processing In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg’s Uncertainty Principle, which says that both quantities cannot be simultaneously measured precisely. Recently, researchers have been developing novel techniques, such as “weak measurement,” to measure both...

New Hybrid Energy Transfer System Developed
2014-05-28 11:13:55

University of Southampton Scientists from the University of Southampton, in collaboration with the Universities of Sheffield and Crete, have developed a new hybrid energy transfer system, which mimics the processes responsible for photosynthesis. From photosynthesis to respiration, the processes of light absorption and its transfer into energy represent elementary and essential reactions that occur in any biological living system. This energy transfer is known as Forster Resonance...

Joint Quantum Institute Sending entangled beams through fast-light materials Michael Lewis's bestselling book "Flash Boys" describes how some brokers, engaging in high frequency trading, exploit fast telecommunications to gain fraction-of-a-second advantage in the buying and selling of stocks. But you don't need to have billions of dollars riding on this-second securities transactions to appreciate the importance of fast signal processing. From internet to video streaming, we want...

Turning Light Into Matter: Scientists Say 80-Year-Old Theory Is Provable
2014-05-19 08:30:22

Lawrence LeBlond for redOrbit.com - Your Universe Online First theorized in 1934 by a pair of scientists – Gregory Breit and John Wheeler – turning light into matter was deemed a fantastical and equally impossible feat. By smashing two photons together at a high rate of speed, the scientists hypothesized that it could create an electron and a positron. An occurrence of such magnitude was deemed extremely rare and difficult to reproduce. So rare that it has never been observed in any...

HADES Experiments Searching For Dark Matter
2014-05-13 03:30:32

Helmholtz-Zentrum Dresden-Rossendorf Although Dark Energy and Dark Matter appear to constitute over 95 percent of the universe, nobody knows of which particles they are made up. Astrophysicists now crossed one potential Dark Matter candidate – the Dark Photon or U boson – off the list in top position. This is the result of recent HADES experiments, where researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and from 17 other European institutes try to pin down the nature of...

redOrbit Staff & Wire Reports - Your Universe Online While excitons have been understood in theory for decades, the authors of a new Nature Communications study have directly observed these quasiparticles responsible for energy transfer in solar cells, LEDs and semiconductor circuits for the first time. According to the MIT and City University of New York (CUNY) scientists behind the research, being able to image the motions of the excitons directly could result in significant...

Los Alamos National Laboratory The project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight. A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University of Milano-Bicocca (UNIMIB), Italy. Their project demonstrates that superior light-emitting properties...

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...
