how difficult would it be to fabricate a solid-state quantum lattice of engineered voids to act like a dense array of qubits?

Not as hard as mass production and scaling, judging by the history of nanotechnologies. It makes me wonder whether superhuman AI engineers would (hypothetically) choose to bust out with new expensive shit or continue to iteratively build on existing technology.

Not difficult. The difficulty is making it stable and more importantly cheaper. Quantum computers may be 100 times faster than regular computers per bit but if they are 10000 times more expensive per bit to build they will never be built. As of now regular flops are cheaper than quantum flops

OP, could you explain what the fuck a solid state quantum lattice is? You want to drill a bunch of fucking holes in silicon or something?

yes. basically the goal is to desorb atoms from a hydrogen-passivated silicon surface, which become single-atom-wide voids, which can localize charge or spin states. from there i'd create donor chains, logic gates, quantum simulators, all on the atomic scale. the question is what can let me desorb on the atomic scale precisely like that. i was thinking scanning tunneling microscopy but it would be absurdly slow, but that's also all i got that would be precise enough.
