A Single-Photon Server with Just One Atom
Every time you switch on a light bulb, 10 to the power of 15 (a million times a billion) visible photons, the elementary particles of light, are illuminating the room in every second. If that is too many for you, light a candle. view more (2007-03-13)
New quantum state: two electrons trapped in an excited atom
Researchers from Universitat Autònoma de Barcelona and the University of Salamanca have discovered a method to generate a new quantum phenomenon which had never been explored until now: simultaneous trapping of two particules between two excited energy states. The research, reported in Physical Review Letters may have important applications... view more... (2002-01-23)
NIST physicists demonstrate quantum entanglement in mechanical system
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated entanglement-a phenomenon peculiar to the atomic-scale quantum world-in a mechanical system similar to those in the macroscopic everyday world. view more (2009-06-04)
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...

'Science:' Novel quantum effect directly observed and explained
An international research team has succeeded in gaining an in-depth insight into an unusual phenomenon, as reported in the current edition of the high-impact journal "Science". view more (2009-02-13)
McCormick Researchers Take Step Toward Creating Quantum Computers
For now, full-fledged quantum computers are the stuff of science fiction - in last summer's blockbuster movie Transformers, the bad guys use quantum computing to break into the U.S. Army's secure files in just 10 seconds flat. view more (2008-04-09)
Moving a bit nearer to a quantum computer
By the time you`ve had your new computer for six months, much faster processors will already be on the market. But there is a limit to how fast conventional computers can become. This is because computers process information in a step-by-step fashion, carrying out each part of the process in turn. To make things work really fast, we need to build... view more... (2002-07-23)
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)
True randomness upon request
The number of applications requiring random numbers increases continuously. They are used for example in cryptographic applications to guarantee the secrecy of electronic communications, in scientific calculations or in chance games and lotteries. In spite of this, their generation remains a difficult task. The Group of Applied Physics and the... view more... (2004-03-17)
Laser-cooling brings large object near absolute zero
Using a laser-cooling technique that could one day allow scientists to observe quantum behavior in large objects, MIT researchers have cooled a coin-sized object to within one degree of absolute zero. view more (2007-04-09)
Quantum Systems Could Flout Physics Law
Scientists in the Weizmann Institute's Faculty of Chemistry, together with colleagues in Germany, have made a startling prediction: Simply 'taking the temperature' of certain quantum systems at frequent intervals might cause them to disobey a hard and fast rule of thermodynamics. view more (2008-06-03)
'Smart' nanoprobes light up disease
Researchers from Rice University's Center for Biological and Environmental Nanotechnology (CBEN) have developed a "smart" beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases. view more (2005-08-02)
Quantum Evolution - The New Science of Life
A clue to understanding life is the realisation that its dynamics are different than those that rule the non-living. For inanimate objects, the dynamics we see are the product of the disordered motion of billions of particles; they are a kind of average dynamics. At the macroscopic level we see patterns and order, but at the molecular level there... view more... (2000-01-31)
Magnetic transistor could 'dial in' quantum effects
A team of theoretical and experimental physicists from Rice University is preparing a unique probe in hopes of "dialing in" elusive quantum states called "quantum criticalities." view more (2005-12-13)
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 paper offers insights into 'blinking' phenomena
A new paper by a team of researchers led by University of Notre Dame physicist Bolizsár Jankó provides an overview of research into one of the few remaining unsolved problems of quantum mechanics. view more (2008-07-02)
Infants are able to detect the 'impossible' at an early age
If you've ever been captivated by an M.C. Escher drawing of stairways that lead to nowhere or a waterfall that starts and ends at the same place, then you are familiar with what Psychologists describe as "impossible" objects and scenes. view more (2007-03-20)
Quantum Effects Make the Difference
The atomic constituents of matter are never still, even at absolute zero (-273.15 degrees Celsius). This consequence of quantum mechanics can result in continuous transition between different material states. Physicists at the Max Planck Institute for Chemical Physics of Solids have studied this phenomenon using ytterbium, rhodium and silicon at... view more... (2007-03-05)
ESA takes steps toward quantum communications
A team of European scientists has proved within an ESA study that the weird quantum effect called 'entanglement' remains intact over a distance of 144 kilometres. view more (2007-06-13)
Stanford researchers hear the sound of quantum drums
Forty years ago, mathematician Mark Kac asked the theoretical question, "Can one hear the shape of a drum?" view more (2008-02-11)
