How to read this. Threat City heights use a logarithmic scale: breaking RSA-2048 is estimated to require on the order of a million-plus physical qubits, so even the tallest real building today is a small fraction of the “Q-Day” reference line at the top. Raw qubit count is not the whole story — error rates and logical-qubit counts matter more — so treat Threat City as orientation about hardware scale, not a literal break-capability meter. Defense City heights reflect real NIST milestones (FIPS 203/204/205 in 2024, HQC in 2025) and the NIST IR 8547 deadlines (RSA/ECC deprecated after 2030, disallowed after 2035). Outlined buildings are projections or targets, not facts. This is a hand-maintained exhibit, updated as real milestones land — not a live data feed.
