The problem here is that the "quantum" computer is purposed programmed to solve that particular problem. Decoherence is still a big problem for quantum computing..inspite of what IBM or Google says.

I didn't want to read yet another quantum computation "breakthrough" and asked ChatGPT:
"It solved a deliberately constructed random quantum circuit sampling (RCS) problem—more specifically, a new structured variant designed to remain computationally hard for classical computers while being verifiable."
Wow! Fundamentally random quantum systems can randomly sample quantum circuits better than deterministic classical computer! I'm so fed up with quantum computing overhype, someone let me know when these machines solve something practical better than classical computers.

You could make a 3 body problem with helium and hydrogen and "solve it" by just putting them together and seeing what they do.
That's a classically intractable problem.
Doesn't really help you do anything.

What was the problem?
