An international team including scientists from the London Centre for Nanotechnology (LCN) today publishes findings in the journal 'Proceedings of the National Academy of Sciences' (PNAS) demonstrating the dramatic effects of quantum mechanics in a simple magnet.   view more (2007-09-24)

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)

Scientists create world's most efficient light-bulb
Scientists have successfully produced the most efficient light bulb ever - but on the microscopic scale. Researchers at Trinity College, Dublin have discovered a technique which significantly improves the output of light from quantum dots, and also allows their light to be focussed and manipulated easily. Their findings are published today in the... view more... (2003-08-27)

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)

McGill researchers squeeze light out of quantum dots
McGill University researchers have successfully amplified light with so-called "colloidal quantum dots," a technology that had been written off by many as a dead-end.   view more (2009-04-03)

European computer scientists seek new framework for computation
There have been several revolutions during the 60 year history of electronic computation, such as high level programming languages and client/server separation, but one key challenge has yet to be fully resolved.   view more (2008-10-30)

Researchers untangle quantum quirk
Quantum computing has been hailed as the next leap forward for computers, promising to catapult memory capacity and processing speeds well beyond current limits. Several challenging problems need to be cracked, however, before the dream can be fully realized.   view more (2008-06-11)

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 computers will require complex software to manage errors
Highlighting another challenge to the development of quantum computers, theorists at the National Institute of Standards and Technology (NIST) have shown* that a type of software operation, proposed as a solution to fundamental problems with the computers' hardware, will not function as some designers had hoped.   view more (2009-04-09)

FSU researchers' material may lead to advances in quantum computing
Scientists at Florida State University's National High Magnetic Field Laboratory and the university's Department of Chemistry and Biochemistry have introduced a new material that could be to computers of the future what silicon is to the computers of today.   view more (2007-10-09)
