| Rush a light wave and you'll break its data, say scientists Posted: 30 May 2014 09:44 AM PDT Quantum information can't break the cosmic speed limit, according to researchers. The scientists have shown how attempts to 'push' part of a light beam past the speed of light results in the loss of the quantum data the light carries. The results could clarify how noise might limit the transfer of information in quantum computers.  |
| Get ready for computers of the future Posted: 29 May 2014 11:20 AM PDT Experts expect multiple computing device-level technologies in the future, rather than one dominant architecture. About a dozen possible next-generation candidates exist, including tunnel FETs (field effect transistors, in which the output current is controlled by a variable electric field), carbon nanotubes, superconductors and fundamentally new approaches, such as quantum computing and brain-inspired computing.  |
