NATO Publishes Quantum Technology Roadmap as Alliance Prepares for a Post-Classical Era

NATO has released a Quantum Technology roadmap, setting out how the Alliance intends to develop, adopt and safeguard a family of technologies that many defence planners believe will reshape sensing, navigation, computing and secure communications in the decades ahead.

The publication builds on work NATO has been undertaking for several years. Quantum technologies have been designated by the Alliance as one of its priority emerging and disruptive technology areas, alongside artificial intelligence, autonomy, biotechnology and space. NATO approved its first strategy dedicated to quantum technologies in early 2024, and a roadmap represents the natural next step: translating broad strategic intent into sequenced, practical objectives that nations and NATO bodies can work towards together.

From strategy to sequencing

Strategies describe ambition. Roadmaps describe order of operations. For an alliance of 32 member states with widely varying levels of scientific capacity, industrial base and defence spending, the challenge is less about identifying promising science than about coordinating it — ensuring that national programmes, laboratories and companies are pulling in compatible directions rather than duplicating effort or producing systems that cannot work together.

That coordination problem is particularly acute in quantum. The field spans several distinct technology families that mature at different speeds. Quantum sensing and metrology — including atomic clocks, gravimeters and magnetometers — is comparatively close to fielded use and has obvious military relevance, not least for navigation in environments where satellite positioning signals are jammed or spoofed. Quantum communications and key distribution sit somewhere in the middle. Large-scale, fault-tolerant quantum computing remains a longer-term prospect, though one with consequences serious enough that governments are already acting on it.

The encryption question

The most widely discussed security implication is cryptographic. Much of the encryption that protects military, governmental and commercial data today relies on mathematical problems that a sufficiently powerful quantum computer could, in principle, solve far faster than conventional machines. Because adversaries can collect encrypted traffic now and decrypt it later, the risk is not purely hypothetical or deferred. This has driven a global push towards post-quantum cryptography — classical algorithms designed to resist quantum attack — and migration planning across defence and critical national infrastructure.

For NATO, whose operations depend on interoperable secure communications between dozens of national systems, any cryptographic transition is a formidable undertaking. Standards, timelines and interoperability requirements all need to be aligned, and legacy systems with long service lives have to be accounted for.

Industry, talent and allied advantage

A roadmap also signals demand. One persistent complaint from the quantum sector is that the gap between laboratory demonstration and deployable hardware is expensive and slow to cross, and that public-sector buyers often struggle to engage with small, research-intensive firms. NATO has built mechanisms intended to address exactly that, including the DIANA accelerator network and the NATO Innovation Fund, both aimed at connecting deep-tech companies across the Alliance with defence users.

There is a competitive dimension too. Quantum research is a focus of sustained state investment in China and elsewhere, and allied governments have increasingly framed the field in terms of strategic advantage, supply chain resilience and research security — including controls on sensitive exports and scrutiny of foreign investment in start-ups.

Whether the roadmap delivers will depend, as ever, on national follow-through: budgets, procurement decisions and the willingness of members to align programmes. But its publication marks a clear signal that NATO regards quantum technology as a near-term planning problem rather than a distant scientific curiosity. Read More
