Physicists demonstrate that 15=3x5 about half of the time
Computing prime factors may sound like an elementary math problem, but try it with a large number, say one that contains more than 600 digits, and the task becomes enormously challenging and impossibly time-consuming. ...
Scientists demonstrate 'universal' programmable quantum processor
Physicists at the National Institute of Standards and Technology have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics -- th ...
Quantum fractals at the border of magnetism
U.S., German and Austrian physicists studying the perplexing class of materials that includes high-temperature superconductors are reporting this week the unexpected discovery of a simple "scaling" behavior in the electronic ...
On the path to quantum computers: Ultra-strong interaction between light and matter realized
Researchers around the world are working on the development of quantum computers that will be vastly superior to present-day computers. Here, the strong coupling of quantum bits with light quanta plays a pivotal ...
D-Wave researchers demonstrate progress in quantum computing
All-optical magnetic switching promises terahertz-speed hard drive and RAM memory
