> Using the same apparatus, which contains a cloud of ultra-cold sodium atoms, they have even managed to freeze light altogether. Professor Hau says this could have applications in memory storage for a future generation of optical computers. Just when you thought you had the world figured out, they go and pull this. The theoretical limits of silicon based computers will peak in the next 40 years. Optical computer processing speeds start at the highest end silicon based speeds, what does it all mean? Smaller, ultra fast computers…perfect for gaming! > **[Optical computer made from frozen light](https://phys.org/news/2005-04-optical-frozen.html)** > > Scientists learn to process information with 'frozen light'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.

For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers). > Most research projects focus on replacing current computer components with optical equivalents, resulting in an optical digital computer system processing binary data. This approach appears ...
