The researchers have demonstrated the ability to electrically manipulate, at gigahertz rates, the quantum states of electrons trapped on individual defects in diamond crystals. This could aid in the d...
Physics and Astronomy |The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable today.The NIST demonstration, described in Nature Ph...
Physics and Astronomy |Because of its scientific significance and social impact, the project is reported in Volume 54, Issue 17 (September, 2009) of the Chinese Science Bulletin authored by Fang-xing Xu et al.During...
Information Technology |Even tiny, easily overlooked events can completely change the behavior of a complex system, to the point where there is no apparent order to most natural systems we deal with in everyday life....
Physics and Astronomy |Most life on earth depends on the sun to provide the energy needed to sustain its function. For more than a billion years, photosynthesis—a mechanism that has evolved to perfection—has allowed plants ...
Power and Electrical Engineering |Research professor Sergey Prosandeev and professor Laurent Bellaiche of the University of Arkansas and A.R. Akbarzadeh of the University of California-Los Angeles report the state, called incipient fe...
Materials Sciences |Quantum dots---often called artificial atoms or nanoparticles---are tiny semiconductor crystals with wide-ranging potential applications in computing, photovoltaic cells, light-emitting devices and ot...

Physics and Astronomy |The team’s work has the long-term goal of developing quantum computers, but it has borne fruit that may have more immediate application in medical science. Their finding that a candidate “quantum bit”...
Physics and Astronomy |A Tiny, Tunable Well of LightPhotonics, the science of using photons to carry information, promises to continue improving a wide variety of technologies, from computing to high-speed communica...
Physics and Astronomy |Advances by the Rice University lab of James Tour have brought graphite’s potential as a mass data storage medium a step closer to reality and created the potential for reprogrammable gate arrays that...
Physics and Astronomy |In order to achieve control over single electrons in a bunch, ultrashort light pulses of a few femtoseconds duration are needed. Physicists of the Max Planck Institute of Quantum Optics (MPQ) in Garch...
Physics and Astronomy |Compared with our everyday experience, the quantum world – the world of the very small, of atoms and elementary particles – is incredibly bizarre. For example, it is possible for a single particle to ...
Physics and Astronomy |The electric and magnetic properties of solids are impossible to calculate exactly: The complex interactions of the many electrons which underly these phenomena cannot be computed even by the most pow...
Physics and Astronomy |The explosive growth of genomic and proteomic data has ushered in a new era of molecular medicine in which cancer detection, diagnosis and treatment are tailored to each individual's molecular pr...
