Thanks to advances in experimental design, physicists at NIST have achieved a record-low probability of error in quantum information processing with a single quantum bit (qubit)—the first published error rate small enough to meet theoretical requirements for building viable quantum computers.
Physicists at The City College of New York have found a new way to map spiraling light that could help harness untapped data channels in optical fibers. The new model, called a Higher Order Poincaré Sphere, could also advance quantum computing.
The number of farmers with Internet access on a variety of digital gadgets has dramatically increased, changing the way farms do business. Farmers say they're increasingly using the Net to speed up their work flow, improve their farming techniques, market their crops, connect with customers and retailers, and fulfill a variety of regulatory requirements.
Ground controllers turned Robonaut on Monday for the first time since it was delivered to the International Space Station in February. The test involved sending power to all of Robonaut's systems. The robot was not commanded to move; that will happen next week. It is, however, tweeting now.
Hewlett-Packard plans to spin off its personal computer division into a separate business, according to unnamed sources in major news outlets. It marks a reversal from HP's previous stance, in March, when it denied this rumor.
Computer scientists in the field of artificial intelligence have made an important advance that blends computer vision, machine learning, and automated planning, and created a new system that may improve everything from factory efficiency to airport operation or nursing care. It is based on watching football.
The big prize for Google’s latest purchase isn’t Motorola’s lineup of electronics devices, it’s the 17,000 patents the company holds. This intellectual property could protect the company against legal action. If approved by federal regulators, the deal could spark other billion-dollar acquisitions.
A new computer model that describes the evolution of the Internet’s architecture suggests that it bears many similarities to ecosystems in the natural world, including the distinctive hourglass shape. Experts warn that a new, revised Internet could easily repeat this pattern.
By combining two frontier technologies, spintronics and straintronics, a team of researchers from Virginia Commonwealth University has devised perhaps the world's most miserly integrated circuit.
A computer model that tests automobile components for crashworthiness could also be of use to the oil and gas industry, according to researchers at Massachusetts Institute of Technology's (MIT's) Impact and Crashworthiness Laboratory, who are now using their simulations of material deformation in car crashes to predict how pipes may fracture in offshore drilling accidents.
Intel Capital announced a $300 million Ultrabook Fund to help drive innovation in this new category of devices. Ultrabook systems will marry the performance and capabilities of today's laptops with tablet-like features.
A few years ago, Internet connections were so slow in Indonesia that a YouTube clip took 20 minutes to download. Now, the nation of 240 million people is a leader in social networking use, attracting investors and prompting an explosion of start-ups. Experts wonder: Will this growth last?
Last week, security researchers uncovered yet another strain of malicious software aimed at Google's popular Android mobile operating system. That comes a month after researchers found a security hole in Apple Inc., iPhone. Signs abound that hackers beginning to target smartphones, and are getting smarter about doing it.
The new TC Cloud service from Fujitsu, which will be introduced in phases beginning in the third quarter of 2011, is comprised of three services, including a platform for conducting analytical simulations, and analytical applications service, and an analytical help desk, which provides support for setting up and running analytical simulations.
In a new paper authored by California Institute of Technology scientists, researchers describe a new technique to isolate light signals on a silicon chip. The breakthrough resembles the function of a diode on an electronic chip, which isolates signals to prevent interference, and it’s one that scientists have been pursuing for 20 years.
Even the human bloodstream isn't safe from computer hackers. A security researcher who is diabetic has identified flaws that could allow an attacker to remotely control insulin pumps and alter the readouts of blood-sugar monitors. As a result, diabetics could get too much or too little insulin, a hormone they need for proper metabolism.
Computer security firm McAfee Inc. issued a report Wednesday reporting the the targets of a concerted wave of cyberattacks totaling more than 70 entities, mostly in the U.S. The attacks, the company reports, are likely originating from a nation state.
Cheap and readily available, silicon is an attractive choice for integrated photonic circuits. However, silicon suffers high optical loss, so researchers in Singapore have built a new chip that integrates, in addition to a laser, an optical grating that provides gain and steady output wavelengths.
The U.S. Department of Energy's National Renewable Energy Laboratory and Verizon signed a memorandum of understanding that could lead to the development of new innovative ways to reduce energy use in the information and communications technology industry.
Taking advantage of the unique properties of zinc oxide nanowires, researchers have demonstrated a new type of piezoelectric resistive switching device in which the write-read access of memory cells is controlled by electromechanical modulation. Operating on flexible substrates, arrays of these devices could provide a new way to interface the mechanical actions of the biological world to conventional electronic circuitry.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a computational model for analyzing the metabolic processes in rapeseed plants—particularly those related to the production of oils in their seeds. Their goal is to find ways to optimize the production of plant oils that have widespread potential as renewable resources for fuel and industrial chemicals.
After earning an R&D 100 Award in 2010 for its continuous water quality analysis software system, aptly dubbed CANARY, Sandia National Laboratories reports that a number of cities from Cincinnati to Singapore are now using it, and they believe the free software could benefit a great many more utilities.
Researchers from IBM demonstrated the future of large-scale storage systems by successfully scanning 10 billion files on a single system in just 43 minutes, shattering the previous record of one billion files in three hours by a factor of 37.
The Cornell University Center for Advanced Computing (CAC) announced that it is testing the performance of general-purpose GPUs with MATLAB applications in a new research collaboration with NVIDIA, Dell, and MathWorks.
A team of engineering students at The Ohio State University’s (OSU) Center for Automotive Research (CAR) recently began running aerodynamics simulations at the Ohio Supercomputer Center (OSC), one of the first steps in the long and careful process of designing, building, and racing the fourth iteration of their alternative-fuel streamliner.
