On September 29, 2026, NATO officially released its Quantum Technology Roadmap. This framework builds upon the inaugural NATO Quantum Strategy released in 2024, providing an actionable blueprint to systematically transition of quantum technologies into operational deployment across land, air, sea, cyber and space domains. For defence decision-makers, industrial leaders and deep-tech innovators across Allied nations, the publication of this roadmap underscores a clear imperative: maintaining technological superiority requires clear adoption pathways, robust dual-use industrial capacity and standardisation across Allied forces. Aim of the Roadmap The primary aim of NATO’s Quantum Technology Roadmap is to make NATO and Allied armed forces “quantum-ready” by establishing a synchronised, Alliance-wide transition plan. Accelerate Adoption & Capability Development: Shorten the timeline between technological breakthroughs in quantum physics and their practical deployment in military operations. Ensure Operational Freedom of Action: Secure critical command, control and communication networks against quantum-enabled adversarial capabilities. Drive Interoperability & Harmonised Standards: Prevent fragmentation across Allied military architectures by aligning testing, validation and standardisation protocols. Protect the Allied Ecosystem: Safeguard intellectual property, critical supply chains and sovereign industrial capacity from strategic competitors and unauthorised technological leakage. Scope of the Roadmap: Technologies, Governance and Phased Execution The scope of the roadmap encompasses the entire lifecycle of quantum technologies, spanning research and prototyping to full-scale acquisition and cross-domain operational integration. Technology Domains Quantum Sensing & Metrology (PNT): Deploying high-precision sensors and atomic clocks to enable accurate position, navigation and timing in GPS-denied, underwater or electronic warfare environments. Quantum Communications & Safe Cryptography: Securing military communication channels through the rapid adoption of Post-Quantum Cryptography (PQC) and quantum-resistant network architectures. Quantum Computing & Simulation: Utilising advanced computational systems for complex logistics, tactical simulation, materials science and situational awareness optimisation. Execution & Governance Scope Phased Lines of Effort (LoE): The roadmap structures activities into adaptive phases, from identification and experimentation through pilot evaluations to operational adoption. Key milestones include regular prototyping, ongoing ACT Innovation Continuum evaluations and initial comparative assessments beginning in 2027. Institutional Coordination: Implementation is distributed across key NATO entities: Allied Command Transformation (ACT): Lead for use case identification, experimentation and operational piloting. Allied Command Operations (ACO): Defining operational requirements that drive procurement and force integration. Science and Technology Organisation (STO) & NCIA: Conducting research, field trials and establishing an Alliance-wide Quantum Standards Roadmap by 2029. NATO Transatlantic Quantum Community (TQC): Facilitating structured alignment between national authorities, researchers and the defence industry. Complementary Efforts: QBN WG QDS While institutional bodies like NATO shape high-level doctrines and capability architectures, the commercialisation, industrial capacity and supply chain resilience required to deliver these systems rely on a strong European and transatlantic industrial base. To support this bridge between defence requirements and dual-use technological availability, the QBN Working Group Quantum Technologies for Defence & Security (WG QDS) operates as a high-trust, triple-helix platform bringing together ministries of defence, military stakeholders, prime integrators and leading quantum innovators. Focus Areas of WG QDS: Requirement Translation: Mapping real-world defence needs onto existing and emerging quantum hardware and software capabilities. Interoperability & Deployment: Defining structured adoption roadmaps to address procurement bottlenecks, field testing, supply chain security and dual-use scalability. Institutional Alignment: Maintaining long-term strategic engagement with NATO and relevant Ministries of Defence across Allied nations. As an active member of the NATO Transatlantic Quantum Community Industry Network (NATO TQC IN), QBN ensures that the industrial expertise, supply chain realities and scaling challenges of commercial quantum developers directly inform sovereign security objectives and Alliance-wide adoption strategies.

JENA, Germany ‒ As quantum technologies steadily transition into commercial deployments, separating immediate and long-term economic value from marketing hype is becoming a strategically important for leadership across industry, military and policy. Speaking during the opening session of W3+ Fair Jena, our CEO, Johannes Verst, delivered a keynote, “Quantum Applications Reality Check: Business Cases for End-Users and Market Potentials for Supply Chains.” The address provided a clear-eyed assessment of where quantum sensing, quantum computing and quantum security are generating measurable value today across core European industries, including automotive, logistics, defence, manufacturing, chemicals and MedTech. Bridging Supply Chains and Industrial Readiness A central focus of the keynote was the indispensable role of the underlying enabling technologies: there is simply no quantum hardware without high-tech pioneers. Quantum systems achieve market readiness only through precision components, specialised materials and advanced engineering spanning photonics, optics, microelectronics and software. Establishing resilient, collaborative ecosystems is essential to securing these emerging value chains within Europe. This commitment lies at the heart of QBN’s strategy. By bridging deeptech innovators, supply chain leaders and industrial end-users, QBN works to convert European scientific leadership into scalable industrial success. Aligning Policy, Industry and Regional Strategy The opening session brought together leaders from government, research and industry to discuss high-tech sovereignty and market development: Colette Boos-John, Thuringia’s Minister for Economic Affairs, set the political context by highlighting photonics as a flagship beacon for regional economic strength and European competitiveness. Dr. Dominic Dorfner, CEO of JENOPTIK, underscored the necessity of strong, integrated ecosystems in tackling multi-sector challenges across AI, supercomputing, MedTech, and defence. Prof. Andreas Tünnermann, Director of Fraunhofer IOF, offered critical insights into photonics supply chains, particularly regarding defence and security requirements. Fostering European Collaboration Beyond the stage, QBN actively engaged in discussions on technology policy, industrial strategy, and cross-border cooperation, deepening relationships with international delegations from Poland and France alongside long-standing partners from the global photonics community.

Landsberg am Lech, Germany – 2026-09-25 – data cybernetics ssc GmbH, the company behind the quantum state preparation platform Q-Alchemy, has run a full chain of molecular quantum-state experiments on real IBM quantum hardware. The team started from classically computed molecular wavefunctions, turned them into compact preparation circuits, ran them on a physical quantum processor, and reconstructed the resulting states from measurements. They did this for twelve molecular systems, using between 4 and 72 qubits. Loading data into a quantum computer is one of the field’s most persistent bottlenecks. A molecular description that is manageable on paper can need a very long sequence of operations to prepare on hardware. Once the state is prepared, it cannot simply be read back. Measurements return only partial information, so the preparation has to be repeated thousands of times. data cybernetics took on the whole problem at once: making the state, running it on hardware, and rebuilding a result that can be checked against the original. Key results The full pipeline ran on real hardware at every scale attempted. All twelve systems completed the journey on an IBM device with 120 qubits. The campaign took about six and a half hours, and every submitted job returned data. Several reconstructions closely matched their reference states. Fidelity is a similarity score from 0 to 1, where 1 is a perfect match. The results were hydrogen 0.986, lithium hydride 0.964, beryllium hydride 0.949, molecular oxygen 0.929, and nitrogen 0.895. Oxygen and nitrogen ran as 20-qubit circuits on physical superconducting qubits. Fast classical circuit generation at scale. For the largest system, dichromium (Cr₂, 72 qubits), the reference state had 54,167 non-zero entries. Q-Alchemy’s QTucker method generated its preparation circuit in about 53 seconds on a conventional computer. Before hardware noise, the circuit reached a calculated fidelity of about 0.88. Open reporting of limits. The 72-qubit dichromium run executed completely, including 14,351 measured properties, but the final reconstruction failed. The team traced part of this to a reconstruction model that was too compact to describe the state. This gives a concrete target for the next round of work The technologyy The experiment is built on QTucker, data cybernetics’ method for finding structure in quantum states. QTucker uses this structure to build compact preparation circuits and low-rank reconstruction models. The method is described in a research paper and a peer-reviewed book chapter. At no point does the pipeline build a full dense state vector. For 72 qubits, that would mean roughly 4.7 × 10²¹ complex amplitudes. Instead, it works with sparse and low-rank representations throughout. Because the hardware measurements are stored, they can be reused. The team can try better reconstruction methods in software without repeating the expensive hardware runs. “Having a description of a molecule on your laptop does not mean you can simply upload it into a quantum computer,” said Carsten Blank, CEO, data cybernetics. “With this campaign, we have made the whole chain run on real hardware: from a molecular description, to a state prepared on a quantum processor, to a reconstructed result we can evaluate. Several molecules came back as close matches, and the hard cases show us exactly where to improve. We now have a complete testbed for making preparation shorter and reconstruction smarter.” Context and next steps data cybernetics presents the results as an engineering milestone, not a claim of quantum advantage in chemistry. The fidelities compare reconstructed states with approximate reference models. Showing usefulness for chemistry will require checking task-specific properties, such as energies. Next, the team plans to repeat the campaign to measure consistency and to compare the hardware results with controlled simulations. The results also suggest that shorter circuits give better outcomes, so the team will pursue shorter circuits and more flexible reconstruction models. The work was funded by the German Federal Ministry of Research, Technology, and Space (BMFTR) under grant 13N17157 (QROM), and the hardware experiments used quantum credits from the IBM Quantum Startup Program.
