Optical Computer Made From Frozen Light

neutron_p writes "Scientists at Harvard University have shown how ultra-cold atoms can be used to freeze and control light to form the "core" - or central processing unit - of an optical computer. Optical computers would transport information ten times faster than traditional electronic devices, smashing the intrinsic speed limit of silicon technology. This new research could be a major breakthrough in the quest to create super-fast computers that use light instead of electrons to process information. Professor Lene Hau is one of the world's foremost authorities on "slow light". Her research group became famous for slowing down light, which normally travels at 186,000 miles per second, to less than the speed of a bicycle."

      The ISO Library Of Congress is a measure of information, so LoC/fortnight is a measure of data rate.

      The speed of a bicycle is a physical velocity, of about one attoparsec per microfortnight (~1 ft/s).

      That's a pretty large upper limit. We're talking relativistic velocities here. Somehow I doubt a bike can move that fast (ok, one of the new plastic crotch rockets maybe :)
