Two For One In Solar Power
2013-11-18 09:51:03

University of Cambridge Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy available from the more energetic photons in the visible part of the spectrum. When a photon is absorbed it creates a single electronic excitation...

Creating Matter That Behaves Like Luke Skywalker's Light Saber
2013-09-26 07:51:56

redOrbit Staff & Wire Reports - Your Universe Online Scientists from Harvard University and the Massachusetts Institute of Technology (MIT) have joined forces to create a never-before-seen form of matter that is said to behave like the legendary light sabers of Star Wars fame. Harvard physics professor Mikhail Lukin, MIT physics professor Vladan Vuletic and their colleagues were able to coax photons into binding together to form what they describe as “photonic molecules.” In...

Brighter Future From Photonic Quantum Computers
2013-05-13 12:40:14

University of Vienna Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty of Physics, University of Vienna succeeded in prototyping a new and highly resource efficient model of a quantum computer — the boson sampling computer. The results will be published in the upcoming issue of the renowned scientific journal "Nature...

Weizmann Institute researchers suggest one can affect an atom´s spin by adjusting the way it is measured One of the most basic laws of quantum mechanics is that a system can be in more than one state — it can exist in multiple realities — at once. This phenomenon, known as the superposition principle, exists only so long as the system is not observed or measured in any way. As soon as such a system is measured, its superposition collapses into a single state. Thus, we, who...

Reading Photons In Quantum Information Enters A New Phase
2013-01-07 07:44:51

redOrbit Staff & Wire Reports - Your Universe Online A new device developed by researchers at the Joint Quantum Institute (JQI) uses an active detection process to establish a new, more accurate standard for reading quantum information. "Decades ago communications theory established a minimal uncertainty for the accurate transmission and detection of information encoded in overlapping states. The hypothetical minimal detection error using conventional schemes is called the standard...

Researchers Find Limit On CPT Violation From Gamma-Ray Bursts
2012-12-07 15:12:11

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in the journal Physical Review Letters that they have found evidence of a strict limit on CPT violation from polarization of gamma-ray bursts. Photons produced by gamma-ray bursts travel billions of light years to reach the Earth. This makes them excellent probes of space-time structures on extremely small scales. Some quantum gravity theories predict that structures of space-time at extremely short...

Objects Hidden From Sight Reconstructed By Laser System

By combining bouncing photons, the particles of light, with advanced optics, researchers are able to 'see' 3-D images of objects hidden around a corner Inspired by the erratic behavior of photons zooming around and bouncing off objects and walls inside a room, researchers from the Massachusetts Institute of Technology (MIT), Harvard University, the University of Wisconsin, and Rice University combined these bouncing photons with advanced optics to enable them to "see" what's hidden around...

First Heralded Single Photon Source Made From Silicon Demonstrated
2012-06-28 10:53:14

In an important step towards more practical quantum information processing, researchers from the National Institute of Standards and Technology (NIST), the University of California, San Diego; and the Politecnico di Milano in Milan, Italy, have demonstrated the first heralded single photon source made from silicon. This source complements two other recently developed silicon-based technologies–interferometers for manipulating the entanglement of photons and single photon...

BOSTON, April 18, 2012 /PRNewswire/ -- Research shows that over 55% of solar module costs come from consumable materials, yet there has been no one source to help the sector understand the integrated impact of consumables supply and cost - until now. Today, after two years of research and analysis, PHOTON Consulting announces the release of an in-depth "Consumables" database product, powered by PHOTON Consulting's proprietary online data platform, The Wall. "Solar module manufacturers, as...
