EUROCORES conference gives cold quantum matter a European twist Quantum matter has long fascinated the science community as many completely new physical phenomena have emerged from this field. Cold quantum matter can be used for applications such as high-precision clocks, which may run only one second behind per three million years! view more (2008-05-06)
Hackers beware! New technique uses photons, physics to foil codebreakers For governments and corporations in the business of transmitting sensitive data such as banking records or personal information over fibre optic cables, a new system demonstrated by University of Toronto researchers offers the protective equivalent of a fire-breathing dragon. view more (2006-02-23)
New ion trap may lead to large quantum computers Physicists at the National Institute of Standards and Technology (NIST) have designed and built a novel electromagnetic trap for ions that could be easily mass produced to potentially make quantum computers large enough for practical use. view more (2006-07-07)
Artificial atoms make microwave photons countable Using artificial atoms on a chip, Yale physicists have taken the next step toward quantum computing by demonstrating that the particle nature of microwave photons can now be detected, according to a report spotlighted in the February 1 issue of the journal Nature. view more (2007-02-02)
New quantum dot transistor counts individual photons A transistor containing quantum dots that can count individual photons (the smallest particles of light) has been designed and demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-10-12)
Loopy photons clarify 'spookiness' of quantum physics Researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules... view more (2008-03-19)
Quantum Information Processing - Deciding the direction of research Future developments in quantum information processing will radically change the way we store and process information. Its basic aim is to understand how the fundamental laws of quantum physics can be harnessed for the manipulation, storage and communication of information, opening up new... view more (2002-08-16)
Physics breakthrough much ado about 'nothing' How do scientists store nothing? It may sound like the beginning of a bad joke, but the answer is causing a stir in the realm of quantum physics after two research teams, including one from the University of Calgary, have independently proven it's possible to store a special kind of vacuum in a... view more (2008-03-06)
Laser tweezers sort atoms Physicists of the University of Bonn have taken one more important hurdle on the path to what is known as a quantum computer: by using 'laser tweezers' they have succeeded in sorting up to seven atoms and lining them up. view more (2006-07-13)
Quantum decoys foil code-breaking attempts Computer code-makers may soon get the upper hand on code-breakers thanks to a new quantum cryptography method designed at the University of Toronto. Quantum cryptography uses particles of light to share secret encryption keys relayed through fibre-optic communications. view more (2005-07-19)
JILA solves problem of quantum dot 'blinking' Quantum dots-tiny, intense, tunable sources of colorful light-are illuminating new opportunities in biomedical research, cryptography and other fields. But these semiconductor nanocrystals also have a secret problem, a kind of nervous tic. They mysteriously tend to "blink" on and off like... view more (2008-01-24)
Plenty of nothing: A hole new quantum spin Electronic devices are always shrinking in size but it's hard to imagine anything beating what researchers at the University of New South Wales have created: a tiny wire that doesn't even use electrons to carry a current. view more (2006-07-26)
Quantum hall effect observed at room temperature Using the highest magnetic fields in the world, an international team of researchers has observed the quantum Hall effect - a much studied phenomenon of the quantum world - at room temperature. view more (2007-02-16)
Next Step to the Quantum Computer Physicists from the University of Bonn have succeeded in taking a decisive step forward towards processing quantum information with neutral atoms: in the latest issue of the 'Physical Review Letters' vol. 93 (2004) they describe how they managed to set up a quantum register experimentally. Their... view more (2004-10-08)
A resetting signal keeps circadian rhythm on track in Drosophila fruit flies A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). view more (2005-11-10)
Scientists discover new method of observing interactions in nanoscale systems Scientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg's uncertainty principle usually would prohibit, according to a study published Jan. 17 in the journal Nature. view more (2008-01-17)
Future 'quantum computers' will offer increased efficiency... and risks An unusual observation in a University of Central Florida physics lab may lead to a new generation of "Quantum Computers" that will render today's computer and credit card encryption technology obsolete. view more (2008-03-06)
Connect the Quantum Dots By using the unique photophysical properties of quantum dots, researchers Drs. Francisco Raymo, Ibrahim Yildiz, and Massimilliano Tomasulo were able to identify operating principles to probe molecular recognition events with luminescence measurements. view more (2006-07-19)
