Physicists produce quantum-entangled images
Using a convenient and flexible method for creating twin light beams, researchers at the Joint Quantum Institute (JQI) of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Maryland have produced "quantum images," pairs of information-rich visual patterns whose features are... view more...

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)
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 of quantum physics. 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 possibilities in information processing. Research and... view more... (2002-08-16)
Discovery of 'hidden' quantum order improves prospects for quantum super computers
An international team of scientists, including several at The Johns Hopkins University, has detected a hidden magnetic "quantum order" that extends over chains of nearly 100 atoms in a material that is otherwise magnetically disordered. view more (2007-07-27)
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 puff of gas and then retrieve it a split second later. view more (2008-03-06)
Getting closer to the Lord of the Rings
This time next year, ESA's Huygens spaceprobe will be descending through the atmosphere of Saturn's largest moon, becoming the first spacecraft to land on a body in the outer Solar System. Earlier this month, the giant ringed planet Saturn was closer to Earth than it will be for the next thirty years. All the planets orbit the Sun as if on a... view more... (2004-01-16)
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)
Physicists find way to control individual bits in quantum computers
Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single "bit" in a quantum processor without disturbing the information stored in its neighbors. view more (2009-07-08)
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)
Singapore scientists synthesize gold to shed light on cells' inner workings
Highly fluorescent gold nanoclusters for sub-cellular imaging have been synthesized by researchers at the Institute of Bioengineering and Nanotechnology (IBN). view more (2009-04-16)
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)
Dream of quantum computing closer to reality as mathematicians chase key breakthrough
The ability to exploit the extraordinary properties of quantum mechanics in novel applications, such as a new generation of super-fast computers, has come closer following recent progress with some of the remaining underlying mathematical problems. view more (2008-12-22)
Researchers putting a freeze on oscillator vibrations
University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill. view more (2009-06-18)
Evidence of macroscopic quantum tunneling detected in nanowires
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more... view more...

Physicists offer new theory for iron compounds
An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of a new class of high-temperature superconductors. view more (2009-03-13)
Hidden order found in a quantum spin liquid
An international team, including scientists from the London Center for Nanotechnology, has detected a hidden magnetic "quantum order" that extends over chains of 100 atoms in a ceramic without classical magnetism. The findings, which are published today, July 26, by Science, have implications for the design of devices and materials for... view more... (2007-07-27)
