summary

Claims that two‑qubit gate fidelities have reached 99.9% two-qubit fidelity and that Google demonstrated a surface‑code protected logical qubit on a 103-qubit Willow chip are cited, with error correction behaving as theory predicts. Practical RSA‑2048 breaking still requires millions of physical qubits (thousands of logical qubits), vast cryogenic infrastructure, and huge cost, while tens of billions per year fund global efforts. Collect‑now/decrypt‑later storage is already plausible and AI is being used to improve error correction and control.
