U of T physicists are first to 'squeeze' light to quantum limit
A team of University of Toronto physicists have demonstrated a new technique to squeeze light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next-generation atomic clocks, novel quantum computing and our most fundamental understanding of the universe. view more (2009-01-07)
Microwave synthesis connects with the (quantum) dots
Materials researchers at the National Institute of Standards and Technology (NIST) have developed a simplified, low-cost process for producing high-quality, water-soluble "quantum dots" for biological research. view more (2008-06-13)
2 for 1: NIST design enables more cost-effective quantum key distribution
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits, or "keys," for use in quantum cryptography, the most secure method of transmitting data. view more (2008-05-30)
Quantum dot method rapidly identifies bacteria
A rapid method for detecting and identifying very small numbers of diverse bacteria, from anthrax to E. coli, has been developed by scientists from the National Cancer Institute (NCI) and National Institute of Standards and Technology (NIST). view more (2006-03-31)
New nanosensor uses quantum dots to detect DNA
Using tiny semiconductor crystals, biological probes and a laser, Johns Hopkins University engineers have developed a new method of finding specific sequences of DNA by making them light up beneath a microscope. view more (2005-12-06)
Research measures movement of nanomaterials in simple model food chain
New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms. view more (2008-06-02)
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)
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)
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)
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)
First tunable, 'noiseless' amplifier may boost quantum computing, communications
Researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier. view more (2008-10-16)
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)
