The (distant) Future of High Speed Computing
Posted: Tue Dec 18, 2007 6:38 pm
While reading up on one of my current curiosities, quantum mechanics (yeah I got issues
), I ran across some interesting articles on quantum computers. These are interest (yet theoretical) devices that are in the future of computing. In todays CPUs there are many different bits that can either be a 1 or a 0, the fun part of a quantum computer is that the bits (actually called quantum bits or qubits) can exist in a 1 state and a 0 state at the same time. To quote HowStuffWorks article:
There is a lot (and I mean a LOT) of problems left to be worked out with this whole idea, especially considering the fact that we don't fully understand quantum theory yet, but it's an amazing concept and probably one of the only was well break through the silicone wall we are approaching. Thought you guys might want to give some of this stuff a read if your curious but I warn you, it can hurt to try and wrap your brain around quantum mechanics.

And of course Wikipedia
There's quite a few more but these are fairly easy to follow (that's kinda a half truth but have a go anyway)


That, to me at least, is truly amazing and why I get such a kick out of quantum mechanics. Not only can it be many many times smaller (the size of one of the largest atoms, Cesium (Cs), is about 0.5nm compared to our 45nm processor of today and most atoms are quite a bit smaller than Cs) but because each bit can have millions of different states rather than just one, it can potentially "be millions of times more powerful than today's most powerful supercomputers."Today's computers [...] work by manipulating bits that exist in one of two states: a 0 or a 1. Quantum computers aren't limited to two states; they encode information as quantum bits, or qubits, which can exist in superposition. Qubits represent atoms, ions, photons or electrons and their respective control devices that are working together to act as computer memory and a processor. Because a quantum computer can contain these multiple states simultaneously, it has the potential to be millions of times more powerful than today's most powerful supercomputers.
