The AI's read

This makes Quantinuum's planned 2029 computer look more reachable. Lower error rates on the same commercial machine show progress without relying on new hardware. The color code needs 37 physical qubits per logical qubit, compared with 10 for Helix. Each tested increase cut the remaining errors, so the progress outweighs the extra qubit need. Apollo is still planned for 2029, not operating today.
