How would simulating quantum mechanics help with AGI?

My guess is they believe in the Penrose idea that consciousness has something to do with quantum mechanics

Obviously, quantum supremacy is semiologically orthogonal to AGI (Artificial General Inteligence) ontological recursive synapses... this is trivial.

By simulating it

What exactly should get simulated and how do you think quantum mechanics will help with this?

At least the solar system I would say. Quantum mechanics will help you do that in the correct way to obtain what Nature already obtained: general intelligence.
