How smart technology gadgets can avoid speed limits

Speed limits apply not only to traffic. There are limitations on the control of light as well, in optical switches for internet traffic, for example. Physicists at Chalmers University of Technology now understand why it is ...

Terahertz computer chip now within reach

Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times ...

High-speed communication systems based on ultraviolet radiation

Military and civil authorities could benefit from secure optical communication systems that use light to carry messages between moving vehicles. Researchers at KAUST have now demonstrated rapid data transfer using ultraviolet-B ...

Lens trick doubles odds for quantum interaction

It's not easy to bounce a single particle of light off a single atom that is less than a billionth of a metre wide. However, researchers at the Centre for Quantum Technologies at the National University of Singapore have ...

Light to break bandwidth ceiling

The rise of big data and advances in information technology has serious implications for our ability to deliver sufficient bandwidth to meet the growing demand.

Atomic cousins team up in early quantum networking node

Large-scale quantum computers, which are an active pursuit of many university labs and tech giants, remain years away. But that hasn't stopped some scientists from thinking ahead, to a time when quantum computers might be ...
