Don't know about the carbon but I do know the number was less than 10^100 as that was used as a comparison number for something else in another article. (The number of calculation a 333 Qbit processor would be capable of perhaps). Of course I am just working from memory here soooo. On the other hand I am also pretty confident in the numbers I gave as being the ones "they" gave. So take it up with "them".
