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)
INTAS calls 2001: Up to 18.5 MEuro for international scientific research !
On 27 April 2001, INTAS officially opened its Open Call 2001, with an indicative budget of 15 MEuro, for the submission of joint research projects and networks related to the following scientific fields: => condensed matter, plasma, radio and material physics, optics and quantum electronics => life sciences (general & molecular biology,... view more...

NIST physicists boost 'entanglement' of atom pairs
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have taken a significant step toward transforming entanglement-an atomic-scale phenomenon described by Albert Einstein as "spooky action at a distance"-into a practical tool. view more (2006-10-19)
New ion trap may lead to large quantum computers
Physicists at the National Institute of Standards and Technology (NIST) have designed and built a novel electromagnetic trap for ions that could be easily mass produced to potentially make quantum computers large enough for practical use. view more (2006-07-07)
Ultracold test produces long-sought quantum mix
In the bizarre and rule-bound world of quantum physics, every tiny spec of matter has something called "spin"-an intrinsic trait like eye color-that cannot be changed and which dictates, very specifically, what other bits of matter the spec can share quantum space with. view more (2005-12-23)
'Strained' quantum dots show new optical properties
Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier. However, if doctors were to use them in humans, quantum dots could have limitations related to their size and possible toxicity. view more (2008-12-08)
New quantum dot transistor counts individual photons
A transistor containing quantum dots that can count individual photons (the smallest particles of light) has been designed and demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-10-12)
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)
'Superdense' coding gets denser
The record for the most amount of information sent by a single photon has been broken by researchers at the University of Illinois. Using the direction of "wiggling" and "twisting" of a pair of hyper-entangled photons, they have beaten a fundamental limit on the channel capacity for dense coding with linear optics. view more (2008-03-25)
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)
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)
Weizmann Institute Scientists Find New 'Quasiparticles'
Weizmann Institute physicists have demonstrated, for the first time, the existence of 'quasiparticles' with one quarter the charge of an electron. This finding could be a first step toward creating exotic types of quantum computers that might be powerful, yet highly stable. view more (2008-06-03)
Laser tweezers sort atoms
Physicists of the University of Bonn have taken one more important hurdle on the path to what is known as a quantum computer: by using 'laser tweezers' they have succeeded in sorting up to seven atoms and lining them up. view more (2006-07-13)
New device from CU physicist tests uncertainty principle to unprecedented level — and shows that looks can cool
In the submicroscopic world - the domain of elementary particles and individual atoms - things behave in the strange, counter-intuitive fashion governed by the principles of quantum mechanics. view more (2006-09-25)
JILA solves problem of quantum dot 'blinking'
Quantum dots-tiny, intense, tunable sources of colorful light-are illuminating new opportunities in biomedical research, cryptography and other fields. But these semiconductor nanocrystals also have a secret problem, a kind of nervous tic. They mysteriously tend to "blink" on and off like Christmas tree lights, which can reduce their... view more...

Research excellence for UK physics
The Institute of Physics is delighted that the international strength of physics in the UK is recognised in the results of the assessment of UK universities` research published today (14 December) by the Higher Education Funding Council. Dr Alun Jones, chief executive of the Institute said, "It is gratifying that the success of physics throughout... view more... (2001-12-13)
Tandem ions may lead the way to better atomic clocks
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have used the natural oscillations of two different types of charged atoms, or ions, confined together in a single trap, to produce the "ticks" that may power a future atomic clock. view more (2005-07-29)
Physicists find way to control individual bits in quantum computers
Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single "bit" in a quantum processor without disturbing the information stored in its neighbors. view more (2009-07-08)
A Fresh Spin in Quantum Physics: The 'Spin Triplet' Supercurrent
For the first time, scientists have created a "spin triplet" supercurrent through a ferromagnet over a long distance. view more (2006-02-16)
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)
