Silicon nanophotonics: Using light signals to transmit data

(Phys.org)—IBM announced today a major advance in the ability to use light instead of electrical signals to transmit information for future computing. The breakthrough technology – called "silicon nanophotonics" – allows ...

Researchers find way to boost WiFi performance 400-700 percent

As many WiFi users know, WiFi performance is often poor in areas where there are a lot of users, such as airports or coffee shops. But researchers at North Carolina State University have developed a new software program, ...

Speeding algorithms by shrinking data

In computer science, the buzzword of the day is "big data." The proliferation of cheap, Internet-connected sensors—such as the GPS receivers, accelerometers and cameras in smartphones—has meant an explosion of information ...

Dark matter filament studied in 3-D for the first time

(Phys.org)—Astronomers using the NASA/ESA Hubble Space Telescope have studied a giant filament of dark matter in 3D for the first time. Extending 60 million light-years from one of the most massive galaxy clusters known, ...

Magnetic vortex reveals key to spintronic speed limit

(Phys.org)—The evolution of digital electronics is a story of miniaturization - each generation of circuitry requires less space and energy to perform the same tasks. But even as high-speed processors move into handheld ...

Quantum mechanics enables perfectly secure cloud computing

Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. ...

Tool detects patterns hidden in vast data sets

Researchers from the Broad Institute and Harvard University have developed a tool that can tackle large data sets in a way that no other software program can. Part of a suite of statistical tools called MINE, it can tease ...

Using nanophotonics to reshape on-chip computer data transmission

A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able to transmit data ...
