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)
