Nice, but the only downside is that you can't build a processer faster than this because what is faster than light?
There are particles believed to exist called FTL particles (Fast Than Light). One of the more common particles believed to exist are called Tachyons. ( of course there are many that believe they don't exist as well).
Of course there's still that question of turning you're headlights on while going down the highway at 70mph (yeah I'm in the US :-) ) Does that mean the light is traveling at 70 miles faster than the speed of light? Einstein seems to think not.
