Delft University of Technology shines light on atomic transistor
Researchers from Delft University of Technology and the FOM Foundation (Fundamental Research on Matter) have successfully measured transport through a single atom in a transistor. view more (2006-11-27)
Cross-dressing rubidium may reveal clues for exotic computing
Neutral atoms-having no net electric charge-usually don't act very dramatically around a magnetic field. But by "dressing them up" with light, researchers at the Joint Quantum Institute (JQI), a collaborative venture of the National Institute of Standards and Technology (NIST) and the University of Maryland at College Park, have caused... view more...

Harvard University engineers demonstrate quantum cascade laser nanoantenna
In a major feat of nanotechnology engineering researchers from Harvard University have demonstrated a laser with a wide-range of potential applications in chemistry, biology and medicine. view more (2007-10-23)
Scientists create first working model of a 2-qubit electronic quantum processor
A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology--similar to that found in computers and cell phones. view more (2009-07-01)
Growing whiskers that won`t need shaving
As manufacturers try to incorporate more and more functions into electronic gadgets like mobile phones and laptop computers, and at the same time decrease their size, the need for smaller electronic circuit components increases. At the 26th International Conference on the Physics of Semiconductors in Edinburgh on Thursday 1 August, Prof Lars... 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)
A quantum (computer) step
A University of Utah physicist took a step toward developing a superfast computer based on the weird reality of quantum physics by showing it is feasible to read data stored in the form of the magnetic "spins" of phosphorus atoms. view more (2006-11-20)
Oregon physicists don't flip spin but find possible electron switch
University of Oregon researchers trying to flip the spin of electrons with laser bursts lasting picoseconds (a trillionth of a second) instead found a way to manipulate and control the spin -- knowledge that may prove useful in a variety of new materials and technologies. view more (2008-05-28)
Princeton scientists spy an electron dance
A team of scientists led by researchers from Princeton University has discovered a new way that electrons behave in materials. The discovery could lead to new kinds of electronic devices. view more (2008-07-28)
Active optical clock
Institute of Quantum Electronics, School of Electronics Engineering and Computer Science, Peking University, has proposed the concept, principles and techniques of active optical clock. view more (2009-04-13)
Entanglement unties a tough quantum computing problem
Error correction coding is a fundamental process that underlies all of information science, but the task of adapting classical codes to quantum computing has long bumped up against what seemed to be a fundamental limitation. view more (2006-09-29)
News Bits About Qubits: Scientists Store and Retrieve Data Inside an Atom
Another step towards quantum computing - the Holy Grail of data processing and storage - was achieved when an international team of scientists that included researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) were able to successfully store and retrieve information using the nucleus of an atom. view more (2008-10-27)
Tiny infrared laser holds promise as weapon against terror
The difficulty of detecting the presence of explosives and chemical warfare agents (CWAs) is once again all too apparent in the news about the London bombings. view more (2005-08-08)
Hundreds of young codebreakers get ready to take on National Cipher Challenge
Ref: 03/111 9 October 2003 For the second year running the University of Southampton is challenging young people across the UK to try their hand at cracking codes with its National Cipher Challenge, sponsored by the EPSRC, IBM, Bletchley Park and EducationGuardian.co.uk. Over five hundred teams from... view more... (2003-10-09)
Stengthening the glow of nanotube luminescence
Nanotubes are the poster children of the nanotechnology revolution. These tiny carbon tubes - less than 1/50,000 the diameter of a human hair - possess novel properties that have researchers excitedly exploring dozens of potential applications ranging from transistors to space elevators. view more (2005-11-15)
Nanotube flickering reveals single-molecule rendezvous
In the quantum world, photons and electrons dance, bump and carry out transactions that govern everything we see in the world around us. view more (2007-06-08)
Towards a new test of general relativity?
Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of... view more...

Closing In On Quantum Chemistry
Researchers in the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have simulated the process by which a quantum computer could calculate to high precision an important basic property of two small molecules. view more (2005-09-09)
Ultracold atoms produce long-sought quantum mix
In the bizarre and rule-bound world of quantum physics, every tiny speck of matter has something called "spin" - an intrinsic trait like eye color. view more (2006-03-15)
Carbon nanotubes outperform copper nanowires as interconnects
Researchers at Rensselaer Polytechnic Institute have created a road map that brings academia and the semiconductor industry one step closer to realizing carbon nanotube interconnects, and alleviating the current bottleneck of information flow that is limiting the potential of computer chips in everything from personal computers to portable music... view more...
