Quantum coherence possible in incommensurate electronic systems
Researchers at the University of Illinois at Urbana-Champaign have demonstrated that quantum coherence is possible in electronic systems that are incommensurate, thereby removing one obstacle in the development of quantum devices. view more (2006-11-03)
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...

Fast quantum computer building block created
The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego. view more (2008-08-21)
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)
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)
SU Professor Works With International Researchers to Make Quantum Physics Discovery
John F. DiTusa, professor of physics and astronomy at LSU, and his international colleagues have discovered an unusual magnetic material that behaves very differently from the average refrigerator magnet. view more (2007-07-30)
Single spinning nuclei in diamond offer a stable quantum computing building block
Surmounting several distinct hurdles to quantum computing, physicists at Harvard University have found that individual carbon-13 atoms in a diamond lattice can be manipulated with extraordinary precision to create stable quantum mechanical memory and a small quantum processor, also known as a quantum register, operating at room temperature. view more (2007-06-01)
Scientists demonstrate all-fibre quantum logic
A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibres with high fidelity. view more (2009-05-29)
What happens when you pop a quantum balloon?
When a tiny, quantum-scale, hypothetical balloon is popped in a vacuum, do the particles inside spread out all over the place as predicted by classical mechanics" view more (2008-04-18)
Toward a quantum computer, one dot at a time
Researchers at the University of Pittsburgh have developed a way to create semiconductor islands smaller than 10 nanometers in scale, known as quantum dots. view more (2006-01-20)
Bose-Einstein condensation in the solid state
New experimental research shows that half-matter, half-light quasi-particles called polaritons show compelling evidence of Bose-Einstein condensation at the relatively high temperature of 19 degrees Kelvin. view more (2006-09-28)
Quantum ghosts are helpful
The idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance'. view more (2009-04-28)
The fight for the best quantum bit (qubit)
Our results give us, for the first time, the possibility to understand the interaction between just two electrons placed next to each other in a carbon nanotube. view more (2008-06-25)
Magnets in a spin bath
Is quantum mechanics relevant to everyday life? Latest scientific evidence suggests that it is. A paper published in Science based on research from the Paul Scherrer Institute (PSI) in Switzerland and others, reports how quantum computers behave as if they are isolated devices. The extent to which they do this can be regulated by the environment... view more... (2005-04-15)
Quantum memory and turbulence in ultra-cold atoms
Scientists at MIT have figured out a key step toward the design of quantum information networks. view more (2009-07-20)
Experiments at UCSB push quantum mechanics to higher levels
Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically -- but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science. view more (2009-08-12)
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)
New Law for Quantum Computers Disclosed
Arun Kumar Pati, who is currently at the University, but who is based at the Bhaba Atomic Research Centre, Mumbai, India, and Samuel L. Braunstein, at the School of Informatics have published a paper in the current issue of the International Journal, Nature [9 March 2000], describing their discovery of a new law, which they call the quantum... view more...

NIST demonstrates better memory with quantum computer bits
Physicists at the National Institute of Standards and Technology (NIST) have used charged atoms (ions) to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds-more than 100,000 times longer than in previous experiments on the same ions. view more (2005-08-11)
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)
