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 ...
European researchers have made important advances in understanding the major stumbling block to realisation of quantum computers, a phenomenon known as decoherence.
Diamonds are forever – or, at least, the effects of this diamond on quantum computing may be. A team that includes scientists from USC has built a quantum computer in a diamond, the first of its kind to include protection ...
A sort of Holy Grail for physicists and information scientists is the quantum computer. Such a computer, operating on the highly complex principles of quantum mechanics, would be capable of performing specific calculations ...
(PhysOrg.com) -- Last week, Burnaby, British Columbia-based company D-Wave Systems, Inc., announced that it sold its first commercial quantum computer. Global security company Lockheed Martin, based in Bethesda, Maryland, ...
(PhysOrg.com) -- In "ordinary" quantum entanglement, two particles possess properties that are inherently linked with each other, even though the particles may be spatially separated by a large distance. Now, physicists S. ...
(PhysOrg.com) -- For the first time, scientists have successfully teleported information between two separate atoms in unconnected enclosures a meter apart - a significant milestone in the global quest for practical quantum ...
The Viterbi Algorithm, the elegant 41-year-old logical tool for rapidly eliminating dead end possibilities in data transmission, has a new application to go alongside its ubiquitous daily use in cell phone communications, ...
If successfully implemented, quantum communication could be an extremely secure method of transmitting information – but there are major roadblocks to pass. Recently, physicists suggested a way, at least in theory, to overcome ...
One of the most exciting and diverse fields of science today involves quantum information processing. There are many designs for quantum computers suggested, and a few that have been demonstrated. Among the demonstrated suggestions ...
