So the number of continuous parameters describing the state of such a useful quantum computer at any given moment must be at least 2**1,000, which is to say about 10**300. That's a very big number indeed. How big? It is much, much greater than the number of subatomic particles in the observable universe.
I am struggling to come up with some way that this part makes any sense at all. It sounds like the kind of thing someone who is definitely not an expert the area would say. He is expressing the number of possible configurations of 1,000 qubits but that is only something you care about if you are simulating a quantum computer with a classical one. The whole point of quantum computers is that you don't have to do that.
Also a simple counterexample to this sentiment is given later on, when mentioning that Google already has a 72-qubit computer. Just storing the states of a 72-qubit machine would be substantially more than the entire capacity of the internet, implying that since we somehow did it then enumerating all the states is not necessary.
