Record breaking quantum encryption
The latest steps towards an uncrackable code have been taken by scientists in both Switzerland and the US, who have found novel ways of generating and transmitting "quantum keys" respectively. Both techniques are reported today, 12 July 2002, in New Journal of Physics, published jointly by the Institute of Physics and the German Physical... view more... (2002-07-10)
LHC Computing Centres Join Forces for Global Grid Challenge
Today, in a significant milestone for scientific grid computing, eight major computing centres successfully completed a challenge to sustain a continuous data flow of 600 megabytes per second (MB/s) on average for 10 days from CERN in Geneva, Switzerland to seven sites in Europe and the US. The total amount of data transmitted during this... view more... (2005-04-26)
Physicists pin down spin of surface atoms
Scientists who dream of shrinking computers to the nanoscale look to atomic spin as one possible building block for both processor and memory, yet setting the spin of an atom, let alone measuring it, has been a challenge. view more (2007-09-13)
Method slashes quantum dot costs by 80 percent
In an important advance toward the large-scale manufacture of fluorescent quantum dots, scientists at Rice University have developed a new method of replacing the pricey solvents used in quantum dot synthesis with cheaper oils that are commonplace at industrial chemical plants. view more (2005-09-08)
Vanquishing infinity
Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in failure. view more (2009-08-18)
Argonne researcher studies what makes quantum dots blink
In order to learn more about the origins of quantum dot blinking, researchers from the U.S. Department of Energy's Argonne National Laboratory, the University of Chicago and the California Institute of Technology have developed a method to characterize it on faster time scales than have previously been accessed. view more (2007-10-05)
What to do with 15 million gigabytes of data
When it is fully up and running, the four massive detectors on the new Large Hadron Collider (LHC) at the CERN particle-physics lab near Geneva are expected to produce up to 15 million gigabytes, aka 15 petabytes, of data every year view more (2008-11-03)
Scientists create first working model of a 2-qubit electronic quantum processor
A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology--similar to that found in computers and cell phones. view more (2009-07-01)
Physics World Digest: August 2002 edition
Physicists see eye to eye with opthamologists Glaucoma is one of the leading causes of blindness in adults - yet over half of us who have the disease do not realise that we are suffering from the condition. While the disease can be treated if caught soon enough, early diagnosis relies on regular screening programmes that can be expensive and... view more... (2002-08-01)
Getting warmer -- Leeds research brings terahertz closer to everyday use
A collaboration between the Universities of Leeds and Harvard has turned the heat up on terahertz technology, bringing a handheld terahertz device a step closer to reality. view more (2008-03-31)
Mechanics: Ordinary meets quantum
At the quantum level, the atoms that make up matter and the photons that make up light behave in a number of seemingly bizarre ways. view more (2009-06-22)
Carbon-based quantum dots could mean 'greener' safer technology in medicine and biology
Chemists at Clemson University say they have developed a new type of quantum dot that is the first to be made from carbon. view more (2006-05-24)
Putting the new generation of hi-tech applications to the test
INNOVATIVE entrepreneurs and company bosses wanting to develop the next generation of mobile technology now have the chance to put their ideas to the test at a unique, state-of-the-art facility run by Staffordshire University. Staffordshire University is recognised as a national leader in mobile and wireless technology. Its Faculty of Computing,... view more... (2004-02-11)
NIST photon detectors have record efficiency
Sensors that detect and count single photons, the smallest quantities of light, with 88 percent efficiency have been demonstrated by physicists at the National Institute of Standard and Technology (NIST). view more (2005-06-02)
Tossing a coin in the microcosm
When you toss a coin, you either get heads or tails. By contrast, things are not so definite at the microcosmic level. An atomic 'coin' can display a superposition of heads and tails when it has been thrown. view more (2009-07-10)
Small nanoparticles bring big improvement to medical imaging
If you're watching the complex processes in a living cell, it is easy to miss something important-especially if you are watching changes that take a long time to unfold and require high-spatial-resolution imaging. view more (2009-11-18)
Physicists team up to learn how quantum mechanical states break down
Researchers at the US Department of Energy's Ames Laboratory, the University of California, Santa Barbara, and Microsoft Station Q have made significant advancements in understanding a fundamental problem of quantum mechanics -- one that is blocking efforts to develop practical quantum computers with processing speeds far superior to conventional... view more...

First quantum cryptographic data network demonstrated
A joint collaboration between Northwestern University and BBN Technologies of Cambridge, Mass., has led to the first demonstration of a truly quantum cryptographic data network. view more (2006-08-29)
Atom 'noise' may help design quantum computers
As if building a computer out of rubidium atoms and laser beams weren't difficult enough, scientists sometimes have to work as if blindfolded: The quirks of quantum physics can cause correlations between the atoms to fade from view at crucial times. view more (2007-03-05)
New imaging technique reveals the atomic structure of nanocrystals
A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). view more (2009-02-19)
