New developments in quantum computing

Quantum computers are computers that exploit the weird properties of matter at extremely small scales. Many experts believe that a full-blown quantum computer could perform calculations that would be hopelessly time consuming on classical computers, but so far, quantum computers have proven hard to build. Researchers have planned an experiment that, if it worked, would offer strong evidence that quantum computers can do things that classical computers can

World’s first eye-controlled laptop presented at CeBIT 2011

Computer manufacturer Lenovo has partnered with Swedish startup Tobii Technology to launch (at CeBIT in Hannover) the world

Versatile ultra-low power biomedical signal processor

Researchers have developed a versatile ultra-low power biomedical signal processor, CoolBioTM, meeting the requirements of future wearable biomedical sensor systems. The biomedical signal processor consumes only 13pJ/cycle when running a complex ECG (electrocardiogram) algorithm at 1MHz and 0.4V operating voltage. This C-programmable chip is voltage and performance scalable supporting a frequency range of 1MHz up to 100MHz with an operating voltage from 0.4 to 1.2V.

Toward computers that fit on a pen tip: new technologies usher in the millimeter-scale computing era

A prototype implantable eye pressure monitor for glaucoma patients is believed to contain the first complete millimeter-scale computing system.

World's smallest magnetic field sensor: researchers explore using organic molecules as electronic components

Further development of modern information technology requires computer capacities of increased efficiency at reasonable costs. In the past, integration density of the relevant electronic components was increased constantly. In continuation of this strategy, future components will have to reach the size of individual molecules. Researchers have now come closer to reaching this target.

Toward an optical atomic clock: physicists develop atomic frequency standard for one of world’s most precise clocks

Polish physicists have been aiming to build an optical atomic clock, an extremely precise device with an accuracy of one second in a few dozen billion years, since 2008. The last of the three key components of the clock: an atomic frequency standard based on cold strontium atoms has just been developed. The clock itself will be assembled already this year.

Robot hummingbird passes flight tests [+video]

(PhysOrg.com) -- A prototype robot spy "ornithopter," the Nano-Hummingbird, has successfully completed flight trials in California. Developed by the company AeroVironment Inc., the miniature spybot looks like a hummingbird complete with flapping wings, and is only slightly larger and heavier than most hummingbirds, but smaller than the largest species.

Researchers use virtual-reality avatars to create 'out-of-body' experience

Volunteers experienced the virtual bodies as if they were their own, with possible applications in computer games or to transport people digitally to other locations

CEBIT 2011: preparing for the unexpected

How can you plan for an emergency the nature of which you don’t know? Several Fraunhofer institutes are working on strategies and technologies that would help to predict and improve the response to crises. Their solutions are shown at the CeBIT in Hannover (March 1 – 5).

Milestone in path to large-scale quantum computing reached: new level of quantum control of light

An important milestone toward the realization of a large-scale quantum computer, and further demonstration of a new level of the quantum control of light, were just accomplished.

New wireless technology developed for faster, more efficient networks

A new technology that allows wireless signals to be sent and received simultaneously on a single channel has been developed. The research could help build faster, more efficient communication networks, at least doubling the speed of existing networks.
