Laser Light Yields Versatile Manipulation Of A Quantum Bit
2013-05-01 15:09:02

University of California - Santa Barbara By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond —— the nitrogen-vacancy center —— in a method that not only allows for more unified control than conventional processes, but is more versatile, and opens up the possibility of exploring new solid-state quantum systems. Their results are published in the latest edition of the Proceedings of the National...

Quantum Internet With Combined Optical And Electrical Technique
2013-05-01 14:54:34

University of New South Wales An Australian team led by researchers at the University of New South Wales has achieved a breakthrough in quantum science that brings the prospect of a network of ultra-powerful quantum computers - connected via a quantum internet —closer to reality. The team is the first in the world to have detected the spin, or quantum state, of a single atom using a combined optical and electrical approach. The study is a collaboration between researchers from...

Professor Weimin Chen and his colleagues at Linköping University, in cooperation with German and American researchers, have succeeded in both initializing and reading nuclear spins, relevant to qubits for quantum computers, at room temperature. The results have just been published in the renowned journal Nature Communications. A quantum computer is controlled by the laws of quantum physics; it promises to perform complicated calculations, or search large amounts of data, at a...

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...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
