Computer scientists revealed the inner workings today of a chemically assembled nanotransistor a key step in what some describe as a final frontier of super-powerful, inexpensive computers beyond the bounds of silicon.

A team of researchers at the University of California at Santa Barbara has taken a key step towards building a quantum computer by suggesting for the first time a practical way to bring the elusive phenomenon known as "electron spin" under precise control.

Researchers at IBM have successfully demonstrated one of the first real-world examples of quantum computing, in which computer scientists hope to use the properties of atomic-scale particles to push information technology beyond its current limits.
