Researchers Building Computers That Run on Light 133
An anonymous reader writes "Researchers in England are attempting to build a desktop computer that runs on light rather than electronics. A $1.6 million research project starting in June at the University of Bath is focused on developing attosecond technology, which refers to continuously emitting light pulses that last just a billion-billionth of a second."

A billion-billionths of a second = 1E-18 seconds.

Feynman has. In his _Lectures on Computing_, he talks about the ramifications of bidirectional gates (reversible computing, but with a cost in complexity) in the context of entropy conservation. It's pretty interesting stuff.
