System to be Installed at NASA's Ames Research Center, and Operational in Q3 BURNABY, British Columbia and PALO ALTO, Calif., May 16, 2013 /PRNewswire/ -- D-Wave Systems Inc., the world's first commercial quantum computing company, today announced that its new 512-qubit quantum computer, the D-Wave Two, will be installed at the new Quantum Artificial Intelligence Lab, a collaboration among NASA, Google and the Universities Space Research Association (USRA). The purpose...

Lawrence Berkeley National Laboratory From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs – and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes. Now scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and...

Synthetic Diamond Material Integral to Achieving Quantum Entanglement Between Atom-like Defects in Two Pieces of Diamond, Driving Advancements in Information Technologies and Fundamental Physics SAN FRANCISCO, May 3, 2013 /PRNewswire/ -- Element Six, the world leader in synthetic diamond supermaterials and member of the De Beers Group of Companies, today announced in collaboration with Delft University of Technology the entanglement of electron spin qubits (quantum bits) in two...

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 Academy of the...

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 the...

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 speed that...

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...

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...

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...
