Australian Engineers Create Functional Quantum Bit Based On The Nucleus Of A Single Atom In Silicon
2013-04-18 10:48:04

University of New South Wales A team of Australian engineers at the University of New South Wales (UNSW) has demonstrated a quantum bit based on the nucleus of a single atom in silicon, promising dramatic improvements for data processing in ultra-powerful quantum computers of the future. Quantum bits, or qubits, are the building blocks of quantum computers, which will offer enormous advantages for searching expansive databases, cracking modern encryption, and modelling atomic-scale...

No More Loopholes For Photons
2013-04-15 14:53:36

University of Vienna 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. The researchers have thus provided the most complete experimental proof that the quantum world is in conflict with our everyday experience. The results of this study appear this week in the renowned journal Nature (Advance Online Publication/AOP). When we observe an object, we make a number of intuitive assumptions,...

Einstein's "Spooky Action" Theory Could Be Tested Aboard Space Station
2013-04-10 12:02:29

April Flowers for redOrbit.com - Your Universe Online "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. Researchers have proposed a solution to this in a new study published in the New Journal of Physics. To test the limits of Einstein's "spooky action" and potentially...

Rubidium Vapor Stores Visual Images
2013-04-04 19:22:16

Lee Rannals for redOrbit.com — Your Universe Online Scientists have demonstrated how they are able to store visual images within a thin vapor of rubidium atoms. Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland reported in the New Journal of Physics about how they used the cloud of atoms as an optical memory device. The team believes their work could be helpful in creating memory for quantum...

German Researchers Take Next Step In Quantum Communications
2013-04-03 14:44:48

Brett Smith for redOrbit.com - Your Universe Online Quantum-based communications is still in its infancy, but the technology is widely expected to become used as the next generation of secure data transfer. According to a new report in Nature Photonics, a group of German physicists has announced the successful transmission of a quantum security key from an aircraft to a ground station via laser, overcoming one of the technology´s biggest hurdles: the ability to transmit and receive...

Quantum Computers Are In Lockheed's Future
2013-03-24 06:27:59

redOrbit Staff & Wire Reports - Your Universe Online A US-based aerospace and defense developer is looking to become the first company in the world to use quantum computing technology as part of its commercial business ventures. According to Quentin Hardy of the New York Times, Lockheed Martin is planning to use one of the next generation computers, which theoretically will be able to complete complex calculations exponentially faster than modern technology, to help create and test...

Major Step Towards Quantum 'Internet' Signaled By Laser-like Photons
2013-03-19 13:30:09

University of Cambridge The realization of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'internet'. The number of transistors on a microprocessor continues to double every two years, amazingly holding firm to a prediction by Intel co-founder Gordon Moore almost 50 years ago. If this is to continue, conceptual and technical advances...

Technology will continue to be a leader in the development of quantum computing architectures Recently Science Magazine invited JQI fellow Chris Monroe and Duke Professor Jungsang Kim to speculate on ion trap technology as a scalable option for quantum information processing. The article is highlighted on the cover of this week's issue, which is dedicated to quantum information. The cover portrays a photograph of a surface trap that was fabricated by Sandia National Labs and used to trap...

Word of the Day
  • Scandinavian punch made of claret and aquavit with spices and raisins and orange peel and sugar.
This word comes from the Swedish 'glogg,' which is an alteration of 'glodgat,' mulled (wine).
