Zero-Index MetaMaterial Holds Promise For Future Quantum Networks And Light Sources
2013-12-06 08:25:49

Lawrence Berkeley National Laboratory The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today’s supercomputers. For the benefits of this new Information Age 2.0 to be fully realized, however, quantum computers will need fast and efficient multi-directional light sources. While quantum technologies remain grist for science fiction, a team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley...

Ten Times More Throughput On Optic Fibers
2013-12-04 12:56:47

Ecole Polytechnique Fédérale de Lausanne EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers; Their simple, innovative solution reduces the amount of space required between the pulses of light that transport data Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology. However, their capacity is limited, because the...

Method could be a step toward quantum computing Picture two light beams intersecting one another in space. When the beams touch one another, does the light bend? Reflect? Combine into a single beam? The answer, of course, is the light beams do nothing; they simply continue on their path. That is because in most media — including air, water, and vacuums — particles of quantized light beams called photons do not interact. But in certain crystalline materials and with a powerful...

World's Shortest Laser Pulse Created By Researchers
2012-09-04 14:32:27

A University of Central Florida research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action — something that has been hidden from view until now. UCF Professor Zenghu Chang from the Department of Physics and the College of Optics and Photonics, led the effort that generated a 67-attosecond pulse of extreme ultraviolet light. The results of his research are published online under Early Posting...

Word of the Day
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
