CRQC Readiness Benchmark (Q-Day Estimator)

Use the CRQC Readiness Benchmark (Q‑Day Estimator) to turn assumptions into a defensible, crypto‑specific forecast. The tool converts four inputs, LQC (logical qubits), LOB (logical operations budget), QOT (logical ops/sec), and an annual growth factor, into a Composite CRQC Readiness Score and a projected “Q‑Day” (when week‑scale factoring of RSA‑2048 becomes practical). Start with Conservative / Median / Aggressive presets, then tweak to match vendor claims or your own view of roadmaps and error‑correction progress. This is intentionally focused on cryptographic breakability, not generic “quantum advantage,” so it may diverge from headline qubit counts.
