Internet of Things Reality Check: Obstacles may limit a Connected World

February 13, 2015 11:31 am | by Inderscience | News | Comments

Connecting different kinds of devices, not just computers and communications devices, to the Internet could lead to new ways of working with a wide range of machinery, sensors, domestic and other appliances. Researchers suggest that we are on the verge of another technological revolution, but practicalities and legal obstacles may stymie the development of the so-called Internet of Things (IoT) if they are not addressed quickly.

Optical Fiber Communications Distance Doubles

February 4, 2015 3:23 pm | by University College London | News | Comments

A new way to process fiber optic signals has been demonstrated, which could double the distance at which data travels error-free through transatlantic sub-marine cables. The new method has the potential to reduce the costs of long-distance optical fiber communications, as signals wouldn’t need to be electronically boosted on their journey, which is important when the cables are buried underground or at the bottom of the ocean.

When Northwestern University professor Luis Amaral set out to test LDA, he found that it was neither as accurate nor reproducible as a leading topic modeling algorithm should be.

Taking a Network Approach to Building Trustworthy Big Data Algorithms

February 2, 2015 1:08 pm | by Emily Ayshford, Northwestern University | News | Comments

Much of our reams of data sits in large databases of unstructured text. Finding insights among e-mails, text documents and Web sites is extremely difficult, unless we can search, characterize and classify their text data in a meaningful way. A leading big data algorithm for finding related topics within unstructured text is LDA. But Luis Amaral found that it was neither as accurate nor reproducible as a leading topic modeling algorithm ...

IBM researchers have announced a cloud-based technology that holds potential to help consumers better protect online personal data, including date of birth, home address and credit card numbers. The technology, called Identity Mixer, uses a cryptographic algorithm to encrypt the certified identity attributes of a user in a way that allows the user to reveal only selected pieces to third parties.

Laser Co-creator and Nobel Laureate Charles Townes dies at 99

January 29, 2015 8:37 am | by Lisa Leff, Associated Press | News | Comments

Charles H. Townes' inspiration for the predecessor of the laser came to him while sitting on a park bench, waiting for a restaurant to open for breakfast. On the tranquil morning of April 26, 1951, Townes scribbled a theory on scrap paper that would lead to the laser, the invention he's known for and which transformed everyday life and led to other scientific discoveries. The 99-year-old Nobel Prize-winning physicist died January 27, 2015.

Einstein-Podolsky-Rosen (EPR) quantum mechanics paradox

Extending Einstein's Spooky Actions for Use in Quantum Networks

January 26, 2015 4:18 pm | by Swinburne University of Technology | News | Comments

Researchers have demonstrated that the 1935 Einstein-Podolsky-Rosen quantum mechanics paradox may be extended to more than two optical systems, paving the way for exploration of larger quantum networks. The experiment also identified properties that may be useful in establishing secure quantum communication networks where shared sequences of numbers created between two parties need to be kept secret from a third party.

Optimizing Information Transfer for a Quantum Internet

January 15, 2015 12:28 pm | by University of Innsbruck | News | Comments

A quantum network requires efficient interfaces over which information can be transferred from matter to light and back. Physicists have shown how this information transfer can be optimized by taking advantage of a collective quantum phenomenon. The collective interaction between the particles and the resonator can now be tuned in order to enhance the creation of single photons.

NORAD Ready to Track Santa’s Flight

December 16, 2014 11:19 am | by North American Aerospace Defense Command | News | Comments

The North American Aerospace Defense Command is once again ready to track Santa’s yuletide journey. It all started in 1955 when a local media advertisement directed children to call Santa direct — only the number was misprinted. Instead of reaching Santa, the phone rang through to the Crew Commander on duty at the Continental Air Defense Command Operations Center. Thus began the tradition, which NORAD has carried on since 1958.

Controlling Light Particle Shape Opens Way to Quantum Internet

December 15, 2014 4:07 pm | by Eindhoven University of Technology | News | Comments

In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a quantum internet. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum internet is control of the shape of these photons. Researchers have succeeded for the first time in getting this control within the required short time.

Engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead to computers that use optics, rather than electricity, to carry data. The optical link is a tiny slice of silicon etched with a pattern that resembles a bar code. When a beam of light is shined at the link, two different wavelengths of light split off

New Frequency Ranges May Make Free Super WiFi Possible

November 24, 2014 4:03 pm | by KIT – University of the State of Baden-Wuerttemberg and National Research Center of the Helmholtz Association | News | Comments

Wireless data transmission largely takes place via WLAN networks, such as WiFi. However, these networks are currently limited to high frequency ranges at 2 GHz and above and, hence, have a limited range. The authors of the study propose to extend the frequencies for free communication to include lower ranges and even increased transmission power.
