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...

To maneuver a car into a parking spot parallel to the road can be quite a challenge. It would be an easy task, of course, if only the vehicle could move sideways. As this is not possible, the sideways motion must be pieced together — sometimes elegantly, sometimes less so — in a series of forward and backward movements and turns on the steering wheel. Such a finely tuned sequence of movements also enables cats to almost always land on their feet after a free fall. Researchers at...

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...

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...

Carbon nanotubes can be used as quantum bits for quantum computers. A study by physicists at the Technische Universitaet Muenchen (TUM) has shown how nanotubes can store information in the form of vibrations. Up to now, researchers have experimented primarily with electrically charged particles. Because nanomechanical devices are not charged, they are much less sensitive to electrical interference. Using quantum mechanical phenomena, computers could be much more powerful than their...

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...

New tech­nolo­gies that exploit quan­tum behav­ior for com­put­ing and other appli­ca­tions are closer than ever to being real­ized due to recent advances, accord­ing to a review arti­cle pub­lished this week in the jour­nal Sci­ence. These advances could enable the cre­ation of immensely pow­er­ful com­put­ers as well as other appli­ca­tions, such as highly sen­si­tive detec­tors capa­ble...

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...

Algorithm
2013-12-16 10:46:30

In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculations, automated reasoning, and data processing. An algorithm is an effective technique expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and an initial input, the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states and eventually...
