Europe’s Security at a Crossroads: Navigating AI and Quantum Threats

The world is undergoing a rapid technological transformation, reshaping security and defense in ways we’ve only begun to understand. Artificial Intelligence (AI) is already revolutionizing how militaries operate, from decision-making and intelligence processing to battlefield strategy and autonomous systems. Meanwhile, Quantum Computing (QC) looms on the horizon, promising both unprecedented computational power and a fundamental threat to modern encryption systems.

For Europe, the stakes couldn’t be higher. Strategic autonomy, resilience, and security in a world of multipolar tensions depend on how effectively AI and QC are integrated and secured. The recently published report, Safeguarding Europe’s Security in the Age of AI, explores the growing reliance on software-defined defense and provides a roadmap for how European leaders can navigate this complex landscape.

The Rise of Software-Defined Defense

The traditional military emphasis on hardware—tanks, aircraft, and ships—is giving way to a new era of software-driven capabilities. Modern warfare increasingly relies on AI-powered decision-making, data analytics, and predictive intelligence. From cyber defense to autonomous weapons, AI has the potential to transform how conflicts are fought and won.

This shift is most evident in recent conflicts. The war in Ukraine has showcased how AI enhances intelligence gathering, battlefield coordination, and logistics management. AI-powered drones, real-time data analysis, and machine-learning-assisted targeting have become critical force multipliers. As the pace of digital transformation accelerates, defense strategies must evolve to ensure that these tools remain secure and resilient against adversarial manipulation.

However, AI adoption in security and defense comes with significant risks. AI models can be vulnerable to cyberattacks, data poisoning, and adversarial influence. Ensuring the integrity of AI-driven systems requires a robust security framework, strong oversight, and continuous innovation in cybersecurity.

The Quantum Threat to Security

While AI is already shaping modern warfare, quantum computing presents a different kind of challenge—one that could disrupt the very foundation of cybersecurity.

Quantum computers leverage the principles of quantum mechanics to process information in ways that traditional computers cannot. The most pressing concern is their ability to break current encryption standards. Today’s cryptographic methods, which protect sensitive military and government communications, could become obsolete once quantum computers reach a critical level of processing power.

This isn’t just a hypothetical risk. The concept of “harvest now, decrypt later” means that encrypted data being collected today could be compromised in the future once quantum decryption capabilities mature. Governments and industries must act now to implement Post-Quantum Cryptography (PQC), which is designed to withstand quantum attacks.

Europe must prioritize quantum security efforts to avoid being caught off guard. While some quantum applications remain theoretical, the rapid pace of research suggests that breakthroughs could happen sooner than expected. NATO has already launched a quantum strategy, but implementation will require significant coordination, investment, and regulatory action.

Global AI and QC Competition: Where Europe Stands

AI and quantum technology are not just defense priorities—they are the focal points of global technological competition.

• The United States leads in both AI and QC research, driven by a strong private sector, deep government investment, and military adoption strategies. The U.S. Department of Defense has significantly increased funding for AI-related programs, and companies like Google and IBM are at the forefront of quantum research.
• China has made AI and quantum development a national priority. The Chinese government heavily funds AI-driven military applications and is rapidly advancing in quantum communications, with the successful launch of the Micius satellite for quantum-encrypted messaging.
• Russia is focusing on AI-powered cyber warfare, geospatial intelligence, and electronic warfare, though it lags in quantum computing development due to funding constraints and inefficiencies.
• Europe has strong AI and QC research institutions, but its fragmented approach and lower private-sector investment put it at a disadvantage. The EU has launched initiatives like the European Defense Fund to boost AI and quantum R&D, but without a unified strategy, it risks falling behind in global competition.

To strengthen its position, Europe must increase domestic production of critical components, such as semiconductors and quantum processors, to reduce reliance on foreign suppliers. It also needs a centralized approach to standardizing AI and quantum adoption across EU nations.

Strategic Priorities for Securing Europe’s Future

To maintain strategic autonomy and technological resilience, European leaders must focus on three key areas:

1. Accelerate Innovation & Integration

Emerging technologies evolve at an unprecedented pace, yet European defense procurement processes remain slow and rigid. AI and QC development cycles no longer align with traditional multi-year procurement timelines. Instead, Europe must adopt agile innovation models:

• Encourage Rapid Experimentation: Defense organizations should embrace a test-and-learn approach, piloting emerging AI technologies in real-world scenarios before full-scale deployment.
• Reform Procurement Processes: AI and software development cycles are measured in months, not decades. Procurement strategies must adapt to enable faster adoption of transformative technologies.
• Leverage Synthetic Data: AI training often suffers from data scarcity. By using synthetic data—realistic but artificially generated datasets—militaries can simulate future scenarios and refine AI models more effectively.

2. Strengthen Technological Sovereignty

Europe’s reliance on external suppliers for AI and quantum technologies presents a long-term security risk. To mitigate this, the EU must:

• Increase Domestic Production of Critical Components: Europe should invest in semiconductor fabrication, quantum processors, and secure data infrastructure to reduce dependency on the U.S. and China.
• Create a Centralized AI & Quantum Coordination Agency: A single EU body should oversee research, standardization, and deployment of these technologies across member states.
• Develop a Skilled Workforce: AI and QC expertise must be cultivated through specialized training programs, ensuring that Europe has the talent pool needed to compete on a global scale.

3. Enhance Trust & Interoperability

For AI and quantum technologies to be effectively integrated into defense strategies, interoperability between allies is crucial. This requires:

• A Transatlantic “Common Data Strategy”: NATO members should collaborate on AI training data access and security frameworks to ensure seamless AI model development.
• Standardized AI Governance Models: AI-driven military applications must operate within ethical and legal boundaries. A NATO-wide framework should establish principles for explainability, accountability, and oversight.
• Transparent Ethical Guidelines: To maintain public trust, European governments must clearly define the permissible use cases of AI in defense and security.

Conclusion: The Time to Act is Now

The digital battlefield is evolving, and Europe must act decisively to secure its place in this new reality. AI is already redefining military strategy, while quantum computing threatens to upend global cybersecurity. Europe’s ability to maintain strategic autonomy depends on how quickly it adapts to these challenges.

To stay competitive, European governments must accelerate innovation, strengthen technological sovereignty, and enhance interoperability with allies. The transition to software-defined defense is inevitable, but without proactive leadership, Europe risks falling behind in an era of rapid technological disruption.

The future of European security will not be determined by hardware alone but by the ability to secure and integrate AI and quantum advancements. The time to act is now.
