So, I'm not quite sure I understand. I know that they use CZM atoms for atomic clocks, and they are extremely accurate. So, will this be used for atomic clocks, too? Or is it more accurate? Or is this for something totally different entirely? It appears to me as though this is something different entirely. But I don't see why it could not be used for an atomic clock if it's even more accurate than Seism.
