Quantum computers are the theoretical devices of our future. So small that they make atoms feel fat, and in theory powerful enough one the size of a credit card would be powerful enough to decide everything that will happen ever. The problem has been, up until now, that they are pretty hard to keep stable, only being able to function for nano-seconds at a time and with the simplest problems; that might be changing. It turns out that diamonds seem to be proving to be a more stable and reliable way to design these computers. The best part is that the lower the quality of the diamond the better that it appears that the computer will work, so they might not even be that expensive in the long run.
The down side to this, of course, is that the computer does not appear to be working perfectly—it was only able to produce a 95% accuracy rating when used which is beyond too low for even a basic prototype design. While this is only really succeeds in proof of concept for the team that created it, it is still the first time that anyone has done anything like this. With the leaps forward that man-made diamonds are making, experts are unable to tell the differences between natural and ones made in a lab, it probably won’t be long before we are able to design something exactly as needed for these machines to makes us all cyborgs.
