Is this new processor capable of achieving reliable and practically useful results beyond the capabilities of classical machines? The answer is almost certainly, no.

Yes, and this was true starting with IBM Boston. I think anything before Dec 2025 could be picked apart as too noisy in particular due to crosstalk problems, for example on Pittsburgh. From the IBM Boston QPU build to the R2s, the fidelity allows for compute beyond what classical computers can do for quantum applications.

IBM has an advantage tracker that needs more submissions https://quantum-advantage-tracker.github.io/

It is very irritating when people complain here that it's not faster than classical or other such complaints.

Please, it is still a research project, it's not like a regular computer just faster, it is novel research.

Regarding the quantum side, I would love to know if by programmable qubit are they referring to an error corrected qubit or just one where gates can be applied.

I suspect it means error corrected qubits. I was wondering if there was work being done on algorithms that are noise resistant and as such can take advantage of the raw qubit count instead of the error corrected qubit count.

I would love to work in this area but I think it's all research at the moment. It's really interesting, how it actually works, not just the hand wavy abstractions.
