A Georgia Tech professor recently offered an alternative to the celebrated “Turing Test” to determine whether a machine or computer program exhibits human-level intelligence. The Turing Test — originally called the Imitation Game — was proposed by computing pioneer Alan Turing in 1950. In practice, some applications of the test require a machine to engage in dialogue and convince a human judge that it is an actual person.
Welcome to the second installment of Scientific Computing's holiday gift guide. This...
Computer scientists have developed software that not only detects and eradicates never-before-...
While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum simulation on a smaller scale. In conjunction with developing a general-purpose quantum computer, Martinis’ team worked on a new qubit architecture, which is an essential ingredient for quantum simulation.
Welcome to Scientific Computing's annual holiday gift guide. In this section, we've focused on identifying gifts suitable for the true Geeks out there. However, I believe everyone has a little geek in them, it just needs to be properly nurtured for it to catch fire.
Findings demonstrate how glass can be manipulated to create a material that will enable computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future. The findings show that it’s possible to change the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs.
Highly motivated to organize the Argonne Training Program on Extreme-Scale Computing, Paul Messina reflects on what makes the program unique and a can’t-miss opportunity for the next generation of HPC scientists. ATPESC is an intense, two-week program that covers most of the topics and skills necessary to conduct computational science and engineering research on today’s and tomorrow’s high-end computers.
Researhers are developing a three-layered, multi-biometric approach that tracks the movement of the eye globe and its muscles, and monitors how and where a person's brain focuses visual attention, in addition to scanning patterns in the iris. The system essentially upgrades the security of existing iris recognition technology with nothing more than a software upgrade.
Researchers will begin testing a new computer game that they hope could hold the key to helping visually impaired children lead independent lives. Developed by a team of neuroscientists and video game designers, the Eyelander game features exploding volcanoes, a travelling avatar and animated landscapes.
As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation.
The control of modern infrastructure, such as intelligent power grids, needs lots of computing capacity. Scientists have developed an algorithm that might revolutionize these processes. With their new software, researchers are able to forego the use of considerable amounts of computing capacity, enabling what they call micro mining.
In the digital age in which we live, monitoring, security breaches and hacks of sensitive data are all too common. It has been argued that privacy has no place in this big data environment and anything we put online can, and probably will, be seen by prying eyes. In a new paper, a privacy law expert makes the case that, when properly understood, privacy rules will be an essential and valuable part of our digital future.
Playing violent video games in 3-D makes everything seem more real — and that may have troubling consequences for players, a new study reveals. Researchers found that people who played violent video games in 3-D showed more evidence of anger afterward than did people who played using traditional 2-D systems — even those with large screens.
Bio-engineers are working on the development of biological computers with the aim of designing small circuits made from biological material that can be integrated into cells to change their functions. In the future, such developments could enable cancer cells to be reprogrammed, thereby preventing them from dividing at an uncontrollable rate. Stem cells could likewise be reprogrammed into differentiated organ cells.
Russian scientists have developed a theoretical model of quantum memory for light, adapting the concept of a hologram to a quantum system. The authors demonstrate for the first time that it is theoretically possible to retrieve, on demand, a given portion of the stored quantized light signal of a holographic image — set in a given direction in a given position in time sequence.
The supply chain is ground zero for several recent cyber breaches. Hackers, for example, prey on vendors that have remote access to a larger company's global IT systems, software and networks. In the 2013 Target breach, the attacker infiltrated a vulnerable link: a refrigeration system supplier connected to the retailer's IT system. A counter-measure, via a user-ready online portal, has been developed at the Supply Chain Management Center.
EPFL scientists have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor devices. Interest in entanglement is increasing today, as it challenges the foundations of quantum mechanics itself.
A Purdue-based startup is developing high-temperature "plasmonic metamaterials" that could dramatically increase data-storage capabilities, improve solar-cell and waste-heat recovery performance and provide a new avenue for clinical therapeutics.
Where are the quantum computers? Aren’t they supposed to be speeding up decryption and internet searches? After two decades of research, you still can’t find them in stores. Well, it took two decades or more of research dedicated to semiconductors and circuit integration before we had digital computers. For quantum computers too it will take technology more time to catch up to the science.
Researchers have brought ultra-fast, nano-scale data storage within striking reach, using technology that mimics the human brain. They have built a novel nano-structure that offers a new platform for the development of highly stable and reliable nanoscale memory devices.
A researcher proposes to construct a new quantum computer, able to perform multiple operations in a few seconds, which is based on the diamond structure to process information similarly to regular computers but with their own units of information called qubits that allow much faster data processing, equal to one thousand computers working simultaneously.
Researchers have shown that information stored in quantum bits can be exponentially compressed without losing information. The achievement is an important proof of principle, and could be useful for efficient quantum communications and information storage. Compression is vital for modern digital communication. It helps movies to stream quickly over the Internet and millions of telephone calls to bounce off of satellites.
New research by biomedical engineers at the University of Minnesota shows that people who practice yoga and meditation long-term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience. The research could have major implications for treatments of people who are paralyzed or have neurodegenerative diseases.
Electricity and magnetism rule our digital world. Semiconductors process electrical information, while magnetic materials enable long-term data storage. A University of Pittsburgh research team has discovered a way to fuse these two distinct properties in a single material, paving the way for new ultrahigh density storage and computing architectures.
Building on previous research that twisted light to send data at unheard-of speeds, scientists at University of Southern California (USC) have developed a similar technique with radiowaves, reaching high speeds without some of the hassles that can go with optical systems.
The interaction between atoms and light is well-known and has been studied extensively in the field of quantum optics. However, to achieve the same kind of interaction with sound waves has been a more challenging undertaking. In collaboration between experimental and theoretical physicists, Chalmers University of Technology researchers have succeeded in making acoustic waves couple to an artificial atom.
Electrons that break the rules and move perpendicular to the applied electric field could be the key to delivering next generation, low-energy computers, a collaboration of scientists from The University of Manchester and the Massachusetts Institute of Technology have found. They report a material in which electrons move at a controllable angle to applied fields, similar to sailboats driven diagonally to the wind.
Some mysteries of science can only be explained on a nanometer scale — even smaller than a single strand of human DNA, which is about 2.5 nanometers wide. At this scale, scientists can investigate the structure and behavior of proteins that help our bodies fight infectious microbes, and even catch chemical reactions in action. To resolve these very fine details, they rely on synchrotron light sources like the ALS at Berkeley Lab.
