Researchers show that relatively simple physical systems could yield powerful quantum computers
Quantum computers are devices—still largely theoretical—that could perform certain types of computations much faster than classical computers; one way they might do that is by exploiting "spin," a property ...
Too much entanglement can render quantum computers useless
Work needed to make algal biofuel viable, study suggests
(Phys.org)—Though biofuels from algae hold great promise, Cornell researchers find that more innovation is needed to make the technology economically and energetically viable at a commercial scale.
Delft professor puts kites high on list for renewable energy
Computer simulations for multiscale systems can be faster, better, more reliable
University of Oregon scientists have found a way to correctly reproduce not only the structure but also important thermodynamic quantities such as pressure and compressibility of a large, multiscale system at variable levels ...
HPC means business in Cray XC30-A supercomputer debut
Can we accurately model fluid flow in shale?
(Phys.org)—Given that over 20 trillion cubic meters of natural gas, a third of the United States' total reserves, are thought to be trapped in shale, and given the rush to exploit shale oil and gas resources ...
Using equations to mine nuclear energy resources
Rising energy demands and environmental concerns have intensified the search for valuable energy resources. As myriad public and private entities pursue increased efficiency, reliable renewable energy or ...
Microsoft to open 'app store' in February
Microsoft began wooing developers for a February opening of its first "app store" for computers powered by the US technology giant's Windows software.
Texas Stampede supercomputer to join the eXtreme Digital (XD) program
When most people hear the word "graph," an image springs to mind: a pair of perpendicular lines overlaid with a line, a curve, or bars of different heights.
Modeling plant metabolism to optimize oil production
(PhysOrg.com) -- Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a computational model for analyzing the metabolic processes in rapeseed plants -- particularly ...
Engineers improve allocation of limited health care resources in resource-poor nations
In the developing world, allocating limited health care resources as effectively and equitably as possible is a top priority.
Do we live in a computer simulation? Researchers say idea can be tested
A decade ago, a British philosopher put forth the notion that the universe we live in might in fact be a computer simulation run by our descendants. While that seems far-fetched, perhaps even incomprehensible, ...
