Adding decoy photons to quantum-cryptographic signals should finally make them “unconditionally secure.” Researchers at Toshiba, in Cambridge, U.K., have found a way to plug a security hole that currently limits how far and how fast encryption keys can be distributed using existing quantum-cryptographic systems. The developments could broaden the commercial appeal of “unconditionally secure” quantum …
Professor Andre Geim and Dr Kostya Novoselov from The School of Physics and Astronomy at The University of Manchester, reveal details of transistors that are only one atom thick and less than 50 atoms wide, in the March issue of Nature Materials. Professor Geim and colleagues have shown for the first time that graphene remains …
A contest to build a robot that can operate autonomously in urban warfare conditions, moving in and out of buildings to search and destroy targets like a human soldier, was launched in Singapore on Tuesday. Defence Science and Technology Agency (DSTA) is offering one million Singapore dollars ($652,000) to whoever develops a robot that completes …
Fuel cells have been made efficient for small machines like lawnmowers. Many standard fuel cell designs use electronics to control power output, but such designs require complex systems to manage humidity and fuel recovery and recycling systems to achieve acceptable efficiency. The new process controls the hydrogen feed to match the required power output, just …
