Post-Quantum Cryptography in 2026: First Wave of Binding Compliance Requirements Expected

An infrastructure strategy piece from QuantumXC outlines five PQC predictions for 2026: the first mandatory compliance requirements for financial services and critical infrastructure; dominance of hybrid classical/PQC deployments; hardware acceleration advances to address performance overhead; the need for cryptographic agility in network infrastructure; and executive-level attention driven by quantum computing capability announcements. Federal deadline timelines — including NSA CNSA 2.0 mandating quantum-safe national security systems by January 2027 — are summarised.
