Superconducting qubit array points the way to quantum computers

April 24, 2014 7:46 am | by Julie Cohen, Univ. of California, Santa Barbara | News | Comments

A fully functional quantum computer is one of the holy grails of physics. Unlike conventional computers, the quantum version uses qubits (quantum bits), which make direct use of the multiple states of quantum phenomena. When realized, a quantum computer will be millions of times more powerful at certain computations than today’s supercomputers.

Under some LED bulbs whites aren’t “whiter than white”

April 21, 2014 12:03 pm | by A'ndrea Elyse Messer, Penn State Univ. | News | Comments

For years, companies have been adding whiteners to laundry detergent, paints, plastics, paper and fabrics to make whites look "whiter than white," but now, with a switch away from incandescent and fluorescent lighting, different degrees of whites may all look the same, according to experts in lighting.

MRI, on a molecular scale

April 21, 2014 8:51 am | by Peter Reuell, Harvard Univ. | News | Comments

A team of scientists, led by physicist Amir Yacoby of Harvard Univ., has developed a magnetic resonance imaging (MRI) system that can produce nanoscale images, and may one day allow researchers to peer into the atomic structure of individual molecules. Though not yet precise enough to capture atomic-scale images of a single molecule, the system already has been used to capture images of single electron spins.

Researchers find 3-million-year-old landscape beneath Greenland Ice Sheet

April 18, 2014 3:15 pm | by Joshua Brown, Univ. of Vermont, and Maria-José Viñas, NASA's Earth Science News Team | News | Comments

Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything, including vegetation, soil and even the top layer of bedrock. So a team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice.

Information storage for the next generation of plastic computers

April 17, 2014 9:41 am | by Gary Galluzzo, Univ. of Iowa | News | Comments

Although it is relatively cheap and easy to encode information in light for fiber optic transmission, storing information is most efficiently done using magnetism, which ensures information will survive for years without any additional power. But a new proposal by researchers would replace silicon used in these devices with plastic. Their solution converts magnetic information to light in a flexible plastic device.

The stakes are incredibly high for the safety and compliance efforts of today’s oil and gas industry. Engineers and crews must be trained for increasingly complex processes and procedures used aboard drilling rigs and production platforms. The consequences of inadequate training during oil production can be disastrous to both operator crews and the environment.

Combs of light accelerate communication

April 14, 2014 11:39 am | News | Comments

In a recent demonstration by researchers in Europe, miniaturized optical frequency comb sources allow for transmission of data streams of several terabits per second over hundreds of kilometers. The results, which showed a data rate of 1.44 TB/sec over 300 km, may contribute to accelerating data transmission in large computing centers and worldwide communication networks.

April 14, 2014 11:33 am | News | Comments

Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope. Using a form of adaptive optics, Janelia Farm Research Campus scientists have developed a microscopy technique that can rapidly correct for distortions and sharpen high-resolution images over large volumes of tissue.

New physical phenomenon on nanowires seen for the first time

April 11, 2014 1:06 pm | News | Comments

For optical communication to happen, it is essential to convert electrical information into light, using emitters. On the other end of the optical link, one needs to translate the light stream into electrical signals using detectors. Current technologies use different materials to realize these two distinct functions, but this might soon change thanks to a new discovery by researchers at IBM.

This would replace the current conventional diagnostic method, which is lengthy and is limited to single point measurements.

Even thinner solar cells through use of nanoparticles

April 8, 2014 11:16 am | News | Comments

New research shows that nanostructures could enable more light to be directed into the active layer of solar cells, increasing their efficiency. Prof. Martina Schmid of Freie Univ. in Berlin has measured how irregularly distributed silver particles influence the absorption of light. Nanoparticles interact with one another via their electromagnetic near-fields, so that local “hot spots” arise where light is concentrated especially strongly.
