Post-Quantum Cryptography (PQC)

What's Happening

Quantum computers are advancing toward the ability to crack the encryption that protects virtually all digital communication, financial transactions, and classified data. RSA, ECC, and other widely used cryptographic algorithms will become vulnerable once quantum machines reach sufficient scale — and Google Quantum AI research estimates RSA-2048 could be broken in under one week using fewer than one million noisy qubits. The threat is not theoretical: nation-state adversaries are already executing 'harvest now, decrypt later' attacks, intercepting and storing encrypted data today with the expectation of decrypting it once quantum computers mature. In response, the National Institute of Standards and Technology (NIST) finalized its first three post-quantum cryptographic standards in 2024 (CRYSTALS-Kyber, CRYSTALS-Dilithium, and SPHINCS+) and selected HQC as a backup standard in 2025. NIST has set a 2030 deadline to phase out legacy encryption and a 2035 ban. The White House has earmarked $7.1 billion for agency-wide PQC migrations, mandating transition plans by 2026. The EU issued a coordinated PQC roadmap endorsed by 18 member states, setting 2030 as the compliance deadline for critical infrastructure. The PQC market was valued at approximately $1.15 billion in 2024 and is projected to reach $4.6-7.8 billion by 2030, growing at a CAGR of 37-46%. Roughly 39% of venture capital funding in cybersecurity is now directed toward PQC-focused startups. Major players like IBM, Google, Cloudflare, and Thales are embedding quantum-safe controls into their products, while specialist vendors like PQShield, QuSecure, and Post-Quantum Ltd are building dedicated solutions. The transition is extraordinarily complex — enterprises must inventory every cryptographic asset, test quantum-resistant algorithms for performance, update certificates and key management systems, and ensure backward compatibility. This migration will take years and cost billions, creating a massive and sustained market for PQC tools, services, and consulting.
