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)
Moving Quarks Help Solve Proton Spin Puzzle
New theory work at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has shown that more than half of the spin of the proton is the result of the movement of its building blocks: quarks. view more (2008-09-15)
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)
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)

Improved Spin Transistor from Oxford University
Researchers at Oxford University’s Physics Department have developed an improved version of the “spin transistor,” a device which has the principle operating characteristics of a conventional transistor but with the added benefit of a current output dependent on the strength of the external magnetic field. This exciting new... view more... (2002-08-15)
Spintronics - breakthroughs for next generation electronics
Traditional silicon chips in computers and other electronic devices control the flow of electrical current by modifying the positive or negative charge of different parts of each tiny circuit. However it is also possible to use of the mysterious magnetic properties of electrons - know as "spin" - to control the movement of currents. Many... view more... (2005-04-26)
