Researchers set new record for brightness of quantum dots
By placing quantum dots on a specially designed photonic crystal, researchers at the University of Illinois have demonstrated enhanced fluorescence intensity by a factor of up to 108. Potential applications include high-brightness light-emitting diodes, optical switches and personalized, high-sensitivity biosensors. view more (2007-09-26)
Quantum paradox directly observed -- a milestone in quantum mechanics
In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum... view more...

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)
UA scientists discover quantum fingerprints of chaos
Chaotic behavior is the rule, not the exception, in the world we experience through our senses, the world governed by the laws of classical physics. view more (2009-10-08)
New quantum key system combines speed, distance
Researchers at the National Institute of Standards and Technology (NIST) have built a prototype high-speed quantum key distribution (QKD) system, based on a new detector system that achieves dramatically lower noise levels than similar systems. view more (2007-06-11)
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)
Physicists demonstrate storage and retrieval of single photons between remote memories
A series of publications in the journal Nature highlights the race among competing research groups toward the long-anticipated goal of quantum networking. view more (2005-12-08)
Danish Researchers Break the Limits of the Internet
A team of Danish physicists has taken a crucial step towards an Internet that is faster and more secure than what we know today. The researchers from the Niels Bohr Institute at the University of Copenhagen have created an atomic memory that, in time, will be able to break the limits for Internet communication. The team's breakthrough was... view more... (2004-11-26)
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)
Silicon chips for optical quantum technologies
A team of physicists and engineers has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer. view more (2008-03-28)
Inside a quantum dot: Tracking electrons at trillionths of a second
Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. view more (2005-11-28)
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)
