Two-photon walk a giant stride for quantum computing
Research conducted at the University of Bristol means a number of quantum computing algorithms may soon be able to execute calculations of a complexity far beyond what today's computers allow us to do. The breakthrough involves the use of a specially designed optical chip to perform what's known as a "quantum walk" with two particles ... and it suggests the era of quantum computing may be approaching faster than the scientific establishment had predicted.

We're all aware of how annoying a tangled mass of electrical wires can be. Fortunately, a research effort from Fujitsu is tackling the problem at its very source. During a conference held in the Institute of Electronics, Information and Communication Engineers at Osaka Prefecture University, the Japanese electronics giant announced a major step in developing a wireless recharging technology that can work simultaneously with multiple portable devices.

In an effort to explore what is perhaps the last salient region of our solar system yet to be visited by a spacecraft, NASA has announced Solar Probe Plus, a mission that will launch a probe directly into the sun's atmosphere. The mission will seek to answer some of the outstanding questions about the nature of our very own star, while helping to understand and forecast the radiation environment in which future space explorers will be living and operating.

Adopting a new, highly automated and reconfigurable approach to hardware acceleration, researchers at the University of California, San Diego (UCSD) have come up with a way to harness the unused silicon real estate in smartphones – the so-called "dark silicon" – as special-purpose processors dynamically optimized to perform the most common tasks in an efficient way.

Scientists from the Georgia Institute of Technology have documented a major breakthrough in the production of nanocircuitry on graphene, a material that many envision as the successor of silicon for our electronics needs. Using thermochemical nanolithography (TCNL), the team found that the electrical properties of reduced graphene oxide (rGO) can be easily tuned to reliably produce nanoscale circuits in a single, quick step.

Eye-controlled earphones let you pick up phone calls with a glance
The Japanese wireless carrier NTT DoCoMo has recently developed and demonstrated a peculiar pair of headphones that can precisely detect a user's eye movements without a camera, and use those movements to control electronic devices such as mobile phones and portable music players. DoCoMo started working on this idea back in 2008 by adapting an electrooculogram (EOG), a medical device used for measuring eye response, to their purposes. An EOG works on the principle that the human cornea has a positive electrical charge. As the user looks to the left or right, the charge shifts in the space between the user's ears – a change that can be easily detected by appropriate sensors. Read More
One of the biggest challenges in creating a better light-emitting diode (LED) is the search for a way to efficiently extract the light generated in the semiconductor device into the surrounding air, while avoiding the internal light reflection that is cause for a considerable waste of energy. A team of Japanese researchers have recently managed to achieve just that, in what is believed to be a huge step toward significantly more energy-efficient LEDs. Read More
Researchers at MIT have found that using specially treated thin layers of carbon nanotubes in batteries can boost the amount of power delivered per unit of weight by up to ten times. While the technology still needs improving, its full development and large-scale employment would certainly revolutionize the way we use any electronic devices, from an iPod to an electric car.

An international team of researchers from the University of Surrey, UCL, Heriot-Watt University and the FOM Institute for Plasma Physics have used infra-red laser to obtain precise control of the quantum superpositions of an electron in silicon for the first time . This feat marks yet another leap toward the dream of an affordable, fast and reliable quantum computer. Read More
