However, I still have strong regrets that the author choose to stick the label "quantum" on it just to make it powerful/magical.
Why not call it a massively-interconnected, nano-organic cellular automata computer instead? Sure, it looses its literary flair, but quantum mechanics and computing is already so rarely understood in the public world, I hate to see fiction encouraging a deterministic model.
That would be unrealistic, absurd, and impossible. How are you going to get an infinite amount of computation in finite time with a cellular automaton or a computer made out of discrete components? The only chance of realistic technobabble is quantum effects. That way, you can pull all sorts of mumbo jumbo like "doing infinitely many things in parallel" or "teleporting the results of computation across space without violating causality" or "expressing the future of a simulation in the binary expansion of real number." And the story simply wouldn't work without a deterministic universe.
P.S. I'm not the author.
