A Police Woman Fights Quantum Hacking and Cracking
The first desktop computers changed the way we managed data forever. Three decades after their introduction, we rely on them to manage our time, social life and finances - and to keep this information safe from prying eyes and online predators. view more (2009-07-31)
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)
NEC, JST and RIKEN successfully demonstrate world's first controllably coupled qubits
NEC Corporation, Japan Science and Technology Agency (JST) and the Institute of Physical and Chemical Research (RIKEN) have together successfully demonstrated the world's first quantum bit (qubit) circuit that can control the strength of coupling between qubits. view more (2007-05-04)
Quantum light beams good for fast technology
Australian and French scientists have made another breakthrough in the technology that will drive next generation computers and teleportation. view more (2007-08-27)
Using Carbon Nanotubes For Quantum Computing
The computing community for many years has longed to be able to to carry out high speed calculations using a genuine Quantum Computer because it would facilitate the practical factorisation of very large numbers and the searching of unordered lists and databases. The rapid breaking of secure codes based on prime numbers would have a lot of... view more... (2004-07-15)
Quantum information now readable
Chalmers researchers in Sweden, in an EU project involving colleagues from France, Holland, Germany, Italy and Finland, have shown that outdata from superconductor quantum computers can be read directly, even though the signal consists only of the presence or absence of two electrons, a so-called Cooper pair. How far away are we from a functional... view more... (2002-04-08)
Delft University of Technology rotates electron spin with electric field
Researchers at the Delft University of Technology's Kavli Institute of Nanoscience and the Foundation for Fundamental Research on Matter (FOM) have succeeded in controlling the spin of a single electron merely by using electric fields. view more (2007-11-02)
Quantum computers could excel in modeling chemical reactions
Quantum computers would likely outperform conventional computers in simulating chemical reactions involving more than four atoms, according to scientists at Harvard University, the Massachusetts Institute of Technology, and Haverford College. view more (2008-11-21)
Rutgers researchers 'rewrite the book' in quantum statistical physics
An important part of the decades-old assumption thought to be essential for quantum statistical physics is being challenged by researchers at Rutgers, The State University of New Jersey, and colleagues in Germany and Italy. view more (2006-02-10)
NRL researchers develop optical technique for controlling electron spins in quantum dot ensembles
Scientists are closer to developing novel devices for optics-based quantum computing and quantum information processing, as a result of a breakthrough in understanding how to make all the spins in an ensemble of quantum dots identical. view more (2007-11-16)
Press invite: 26th International Conference on the Physics of Semiconductors
A laser-based system that could revolutionise both medical imaging and communications, progress towards building the first solid state `quantum` computer and developments in nanotechnology are just some the topics being featured at the 26th International Conference on the Physics of Semiconductors. The five-day conference is being organised by the... view more... (2002-07-10)
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)
The impact of its environment on a quantum computer
Scientists have discovered how the performance of a quantum computer can be affected by its surrounding environment. The study, published in the latest issue of the journal Science, will help engineers to better understand how to integrate quantum components into a standard office computer - moving us one step closer to a future of quantum... view more...

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)
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)
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)
First tunable, 'noiseless' amplifier may boost quantum computing, communications
Researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier. view more (2008-10-16)
Imaging quantum entanglement
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)
Fermions do not travel together, theory proved
Fermions tend to avoid each other and cannot "travel" in close proximity. Demonstrated by a team at the Institut d'optique (CNRS/Université Paris 11, Orsay-Palaiseau), this result is described in detail in the January 25, 2007 issue of Nature. It marks a major advance in our understanding of phenomena at a quantum scale. view more (2007-03-12)
Manipulating light on a chip for quantum technologies
A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements. view more (2009-06-09)
