Just watched the part 1 too. This stuff is beyond my understanding, but it's still really interesting to see just what goes into this sort of research. It seems we are actually half decently close to seeing practical quantum computers. I imagine we won't see them in homes any time soon if ever but I could see them being useful for AI and such once refined to the point they can do actual tasks. I can imagine them being scaled down over time too where you basically install a "quantum card" in a regular computer and plug in some chiller lines into it that go to a central chiller system.
9:55 I always thought they make this with photons rather than electrons edit: the extreme UV lithography costs billions of dollars? Wow, never thought it was this complex. Guess the accuracy needed makes it very expensive
