Quantum cryptography gap scan 2026: PQC, QKD, and evidence must be one program.

The June 2026 policy surface is unusually clear. The White House executive order on advanced cryptographic attacks and OMB M-26-15 move U.S. federal agencies toward execution planning for post-quantum cryptography. CISA's product-category guidance gives buyers a practical lens for finding software and hardware that depend on public-key cryptography.

Europe is also moving from principle to roadmap. The NIS Cooperation Group roadmap, supported by the European Commission, creates a synchronized transition path for Member States, while EuroQCI keeps a separate quantum-communication track for infrastructure where physics-based secure links may be justified.

That combination matters. The enterprise question is no longer whether quantum-safe cryptography should be considered. It is how to inventory dependencies, prioritize high-risk systems, test standards, coordinate vendors, and preserve evidence that the transition was controlled.

Quantum cryptography is often used loosely. For enterprise planning, the useful split is sharper. Post-quantum cryptography is a standards and software migration path: algorithms designed to resist quantum attacks while running on classical computers. Quantum key distribution is a physical-layer communication approach that can be valuable in narrow high-assurance links but is not a general replacement for internet-scale cryptographic migration.

A serious Neura Parse service page should therefore avoid selling QKD as a universal answer. The credible offer is crypto-agility: inventory, algorithm selection, hybrid rollout, vendor validation, policy gates, and evidence retention. QKD can be assessed as a specialized option when link budget, geography, physical control, and compliance value justify it.

Most organizations will not fail because they cannot name ML-KEM. They will fail because cryptographic usage is scattered across applications, devices, SaaS contracts, embedded firmware, certificate authorities, VPN gateways, message queues, databases, and partner APIs.

The useful product is a migration control room: discover cryptographic assets, classify risk, assign owners, request vendor attestations, run staged tests, approve cutovers, and export an evidence pack for security, legal, and procurement review.

The first delivery wedge should not be a generic PQC workshop. It should be a scoped assessment for long-lived data, identity systems, signing infrastructure, device fleets, regulated customer data, and third-party dependencies that are expensive to update later.

A credible first phase can produce an asset map, a PQC impact score, vendor outreach pack, algorithm decision register, pilot migration candidates, and a board-level timeline aligned to U.S. and EU policy pressure.
