Scalable, universal quantum computer? Quantum information processed with system comprising optical photon and trapped atom Posted: 09 Apr 2014 12:57 PM PDT When it comes to recognizing complex patterns or to decoding encrypted messages, conventional computers reach their limits. A whole new quality in the communication and processing of data is expected from a technology that exploits the special properties of quantum particles such as superposition and entanglement. Scientists are pursuing a variety of different concepts towards the development of such a quantum computer. One professor follows the strategy of combining two rather dissimilar techniques: quantum communication using photons, and information processing using stationary atoms. His team has now for the first time realized a quantum logic gate between a single photon and a single atom.

New 'switch' could power quantum computing: Light lattice traps atoms, builds networks of quantum information transmitters Posted: 09 Apr 2014 10:47 AM PDT Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists have developed a new method for connecting particles -- one that could help in the development of powerful quantum computing systems. The new technique allows researchers to couple a lone atom of rubidium, a metal, with a single photon, or light particle.

See what a child will look like using automated age-progression software Posted: 09 Apr 2014 10:46 AM PDT Researchers have developed software that automatically generates images of a young child's face as it ages through a lifetime. The technique is the first fully automated approach for aging babies to adults that works with variable lighting, expressions and poses.

Novel ultra-fast electrical circuits use light-generated tunneling currents Posted: 09 Apr 2014 06:36 AM PDT Scientists have successfully designed and fabricated electrical circuits that can operate at hundreds of terahertz frequencies, which is tens of thousands times faster than today's state-of-the-art microprocessors.

Researchers measure smartphone malware infection rates and explore ways to identify infection with previously unknown malware Posted: 08 Apr 2014 08:14 AM PDT Researchers measure smartphone malware infection rates and explore ways to identify infection with previously unknown malware. Smartphones are now ubiquitous, personal and have a lot of personal information about their users. Calls and messaging cost money to users, and smartphones are also used increasingly for more direct financial transactions. Therefore, one of the great fears about smartphone use is the possibility of large-scale viral infection.
