Reconcile These Two Quantum Facts And Tell Me Why NIST Still Have 2035 for PQC Dates

U.S. federal agencies face a 2035 deadline for full post-quantum cryptography (PQC) adoption per NIST/CISA guidelines, despite accelerating global timelines. Other nations, including EU members and allies, have advanced their PQC transition deadlines to 2030 or earlier, citing urgent quantum threats. Recent research suggests 100,000 physical qubits could break RSA-2048 encryption, a threshold multiple quantum firms aim to reach within years. Experts warn most U.S. organizations require five-plus years to fully migrate to PQC, raising concerns about the 2035 timeline’s adequacy against near-term quantum risks. The discrepancy between U.S. timelines and global urgency highlights potential gaps in risk assessment, infrastructure readiness, or strategic prioritization.
