Latest Quantum mechanics Stories

Tokyo, Jan 21, 2011 - (JCN Newswire) - Professor Kohei Itoh, who is developing quantum computers based on silicon semiconductors at Keio University's Faculty of Science and Technology, together with Dr. John Morton at Oxford University and others, has successfully generated and detected quantum entanglement between electron spin and nuclear spin in phosphorus impurities added to silicon. This is the world's first successful generation and detection of...

Scientists have moved a step closer to creating quantum computers by generating 10 billion bits of quantum entanglement in silicon for the first time. According to a team from Britain, Japan, Canada and Germany, whose study was published in the journal Nature on Wednesday, the achievement in silicon has important implications for integration with existing technology. "Creating 10 billion entangled pairs in silicon with high fidelity is an important step forward for us," John Morton...

A new fractional vortex state observed in an unconventional superconductor may offer the first glimpse of an exotic state of matter predicted theoretically for more than 30 years. In a paper published in the January 14 issue of Science, University of Illinois physicists, led by Raffi Budakian, describe their observations of a new fractional vortex state in strontium ruthenium oxide (SRO). Such states may provide the basis for a novel form of quantum computing in which quantum information is...

CAMBRIDGE, Mass., Dec. 21, 2010 /PRNewswire/ -- Raytheon BBN Technologies, a wholly owned subsidiary of Raytheon Company (NYSE: RTN), has been awarded $2.1 million in funding by DARPA (the Defense Advanced Research Projects Agency) for two projects under the Information in a Photon, or InPho, program. The goal of the two projects is to develop new theory and experimental techniques that enable optical communications and imaging systems to operate at their ultimate limits of information...

A mechanical device that operates in the quantum realm tops the journal's list of advances in 2010Until this year, all human-made objects have moved according to the laws of classical mechanics. Back in March, however, a group of researchers designed a gadget that moves in ways that can only be described by quantum mechanics"”the set of rules that governs the behavior of tiny things like molecules, atoms, and subatomic particles. In recognition of the conceptual ground their experiment...

Researchers pave the way for spin computersA research team from the Institut Català de Nanotecnologia (ICN), in Barcelona, has demonstrated a device that induces electron spin motion without net electric currents, a key step in developing the spin computers of the future. The results are published in the Dec 17 issue of the journal Science. The authors are Marius V. Costache and Sergio O. Valenzuela, an ICREA Professor who is leader of the Physics and Engineering of Nanodevices Group at...

Tracking down Cooper pairs: RUB researchers confirm theoretical hypothesisThe results achieved by this research team headed by Prof. Kurt Westerholt and Prof. Hartmut Zabel (Department of Physics and Astronomy at RUB) could contribute to new, power saving components in the future. The researchers reported on their findings in the American Physical Society's noted journal "The Physical Review".Electron pairs in singlet stateIf it were possible to eliminate electrical resistance we...

Milestone reached on the path to integrated quantum technologyQuantum information processing is arguably one of the most fascinating facets of modern quantum physics.A quantum computer operates with quantum bits (qubits) as units of information. Obeying the laws of quantum mechanics, such a computer would be capable of addressing several of the most difficult computational tasks unsolvable with present technology. In the past few decades, scientists learned to perform room-sized experiments...
