Provided by Ken Kingery, Duke University Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal — setting a speed record and making an important step toward realizing superfast light emitting diodes (LEDs) and quantum cryptography. This year's Nobel Prize in physics was awarded for the discovery of how to make blue LEDs, allowing everything from more efficient light bulbs to video screens. While the discovery has had an...

TURKU, Finland, October 1, 2014 /PRNewswire/ -- Novel detection technology is finally breaking through in the life science field The life science field has seen numerous detection technologies come and go over the years. Some are shooting stars and others become the golden standard. Photon upconversion is a novel detection technology that has raised much enthusiasm among researchers during recent years. Now, finally, this technology is becoming commercially available....

Nothing Seems To Stop Quantum Teleportation
2014-09-22 03:25:34

Université de Genève Physicists at the University of Geneva (UNIGE) have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment, carried out in the laboratory of Professor Nicolas Gisin, constitutes a first, and simply pulverizes the previous record of 6 kilometers achieved ten years ago by the same UNIGE team. Passing from light into matter, using teleportation of a photon to a crystal, shows that, in quantum physics, it...

artificial atom generates sound waves
2014-09-13 05:55:40

Chuck Bednar for redOrbit.com - Your Universe Online If you’ve ever wondered exactly what kind of sound would be produced by a single atom, researchers from the Chalmers University of Technology in Sweden have the answer you’ve been looking for, as they have become the first scientists ever to demonstrate the use of sound to communicate with the building blocks of matter. [ Watch the Video: What is in Atom ] Writing in the latest edition of the journal Science, microtechnology...

Light With A Twist
2014-07-21 03:21:54

Australian National University Scientists at The Australian National University (ANU) have uncovered the secret to twisting light at will. It is the latest step in the development of photonics, the faster, more compact and less carbon-hungry successor to electronics. A random find in the washing basket led the team to create the latest in a new breed of materials known as metamaterials. These artificial materials show extraordinary properties quite unlike natural materials. "Our...

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...

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...

  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
