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."

    Actually, most of space is about 3 degrees kelvin.

    For those looking for a better reference of the measure mentioned, Speed of a Bicycle is in between Mum Falling Down the Stairs, and Cat Jumping Out of the Bath.

    Yes, because that makes a lot of difference when compared to 3*10^8 m/s...
