IonQ's 74x Clifford Speedup Is Not a Machine.
IonQ's Oct. 6 note puts Clifford operations at up to 74x and Toffoli gates at up to 5.0x. Q70 and Q102 are codes in a blueprint, not a bookable system.

NVIDIA's CUDA-Q Logical Is Software for Qubits That Do Not Exist Yet
Fermilab cut a five-month fault-tolerant workflow to three weeks. Infleqtion wired qLDPC into the same layer. The qubits are still noisy. The orchestration is what shipped on 14 September.

Quantum Error Correction Hits a New Milestone — but the Finish Line Is Still Far Away
Google and IBM both report below-threshold error rates on logical qubits, but the qubit overhead required for fault-tolerant quantum computing remains enormous.
