Cool, they can store data on a random carbon atom. Or a nitrogen one in the diamond...?

Can they store it in more than just one?

How do they keep track of location of each bit? Can the system reliably reod/write to the atom it’s supposed to, and not the one a couple microns over?

Another unique aspect of this approach is that it’s reversible. “One can write, erase, and rewrite an infinite number of times,” Monge noted. “While there are some other optical storage technologies also able to do this, this is not the typical case, especially when it comes to high spatial resolution. A Blu-ray disc is again a good reference example -- you can write a movie in it but you cannot erase it and write another one.”
