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)
NIST develops novel ion trap for sensing force and light
Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the National Institute of Standards and Technology (NIST) could usher in a new generation of applications because the device holds promise as a stylus for sensing... view more...

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)
Computing a way through the Turing barrier
Mathematicians working in an emerging field somewhere between physics, computer science and philosophy are investigating new ways of 'computing the incomputable' which could radically broaden our understanding of the world. Pure mathematics professor Barry Cooper is leading a European network into a world of 'unsolvable' problems. view more (2005-02-21)
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)
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)
Building a better qubit
Exploiting quantum mechanics for transmitting information is a tantalizing possibility because it promises secure, high speed communications. view more (2009-10-06)
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)
Breakthrough for the computer of tomorrow?
For the first time a material now exists that is not only a semiconductor but also exhibits exploitable magnetic properties at room temperature. Researchers at the Royal Institute of Technology (KTH) in Stockholm, Sweden, have taken the lead in an international race to find the technology of tomorrow. Today's computers process information using... view more... (2003-09-25)
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)
UC Santa Barbara researchers light up 'dark' spins in diamond
Researchers at UC Santa Barbara have potentially opened up a new avenue toward room temperature quantum information processing. By demonstrating the ability to image and control single isolated electron spins in diamond, they unexpectedly discovered a new channel for transferring information to other surrounding spins - an initial step towards... view more...

Physicists create millimeter-sized 'Bohr atom'
Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. view more (2008-07-01)
Trash or treasure? Discarded US computers often get a second life
More computers discarded by consumers in the United States are getting a second life in developing countries than previously believed, according to a new study -- the most comprehensive ever done on the topic. view more (2009-09-02)
A hidden twist in the black hole information paradox
Professor Sam Braunstein, of the University of York's Department of Computer Science, and Dr Arun Pati, of the Institute of Physics, Sainik School, Bhubaneswar, India, have established that quantum information cannot be 'hidden' in conventional ways, or in Braunstein's words, "quantum information can run but it can't hide." view more (2007-02-28)
Argonne, UC scientists reach milestone in study of emergent magnetism
Scientists at the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago have reached a milestone in the study of emergent magnetism. view more (2009-06-19)
Diamonds may be the ultimate MRI probe, say Quantum physicists
Diamonds, it has long been said, are a girl's best friend. But a research team including a physicist from the National Institute of Standards and Technology (NIST) has recently found that the gems might turn out to be a patient's best friend as well. view more (2009-09-23)
Quantum gas microscope offers glimpse of quirky ultracold atoms
Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways. view more (2009-11-05)
Growing Quantum Dots
Now physicists need not fully control the growth of laser crystals, because the crystals grow themselves. Professor Nikolay Ledentsov and his team at the Ioffe Physico-Technical Institute have learned how to provide special conditions in which crystals can grow defectless. Growing crystals with... view more... (2002-09-09)
