Quantum technologies are increasingly recognized as a disruptive frontier that will shape the next generation of industrial strategies. Developments in quantum computing, communication, and sensing promise not only technical breakthroughs but also significant economic and geopolitical consequences. Quantum computing can accelerate drug discovery, materials research, and complex optimization, while quantum communication opens new possibilities for secure data transfer beyond the reach of classical encryption. According to European Commission Reports and National Quantum Initiative Act, leading economies are already investing heavily: the European Union has committed over €1 billion to its Quantum Flagship program, while the United States launched the National Quantum Initiative Act in 2018 to coordinate research and industrial applications. These initiatives underscore the strategic nature of the field. For industrial policy, they also raise important questions: How should governments design roadmaps that foster public–private collaboration? What forms of regulation or incentives are needed to align innovation with competitiveness and security? At the same time, quantum technologies could support sustainability goals, for example through energy-efficient algorithms and advanced climate modeling. Positioning quantum technologies not only as an enabler but as a driver of future industrial policy is essential. Unlike incremental innovations, quantum breakthroughs will actively shape the direction of national strategies, global competitiveness, and sustainability agendas. Recognizing this driver role ensures that policymakers and industries move beyond adaptation, taking a proactive stance in designing resilient and forward-looking industrial ecosystems.
Abstract The burgeoning field of quantum technologies presents a transformative landscape with profound implications for law and development. This abstract outlines some of the rising key issues at this critical intersection, highlighting the urgent need for interdisciplinary engagement and proactive policymaking. The unique characteristics of quantum technologies and related advancements are challenging the existing legal frameworks, particularly in intellectual property. Questions surrounding the patentability of quantum algorithms and hardware, the delicate balance between protecting innovation and fostering open access, and the potential for future patent disputes demand novel legal solutions. Ensuring equitable quantum disparities between developed and developing countries is paramount. Furthermore, the advent of quantum technologies poses a significant threat to current data security protocols. The potential to break existing encryption methods necessitates the rapid development and global adoption of postquantum cryptography. In addition, the societal and ethical implications of enhanced surveillance capabilities of quantum technologies require proactive and careful legal consideration within the privacy and civil liberties framework. Beyond security, there are fundamental ethical and societal considerations with emerging technologies. The dual-use nature of many quantum technologies raises concerns about their potential misuse. Addressing the law and development disparities inherent in this technological revolution is critical. Unequal access to research, funding, and infrastructure risks concentrating the benefits of quantum technologies in a select few nations. International collaborations, flourishing quantum ecosystem, and thoughtful technology transfer policies are essential to ensure that developing countries can participate in and benefit from this progress and enjoy these technologies to the fullest. Finally, the fast pace of innovation necessitates a reevaluation of existing regulatory challenges and innovation bottlenecks. Innovation and development should be fostered, not hindered by regulation. Adapting current legal frameworks and developing new regulations that balance fostering innovation with mitigating potential risks is crucial. There is a pressing need to create international legal standards and shared regulatory framework in the globally interconnected field of quantum technologies. In conclusion, the rise of quantum technologies presents a complex web of ethical, societal, economic, political, legal, and developmental challenges. Addressing these issues effectively requires proactive, collaborative efforts from legal scholars, policymakers, scientists, industry leaders, and the international community to ensure a future where quantum innovation contributes to equitable global development and operates within a robust and ethical legal framework.

Quantum technologies are rapidly moving from scientific research into the arenas of commercialisation and strategic competition, with significant implications for defence and security. While their full military impact may unfold over time, developments in quantum sensing, computing, and communications are already shaping national strategies, industrial ecosystems, and future capability planning. The growing competition among major technological powers highlights the need to act on both the opportunities and risks associated with quantum technologies. Quantum technologies have the potential to enhance military capabilities across domains, from resilient positioning, navigation, and timing to advanced sensing, computing, and secure communications. At the same time, they introduce new vulnerabilities, including risks to current cryptographic systems, supply chains, and technological dependencies. For NATO, the debate is therefore no longer whether quantum technologies matter, but how quickly the Alliance can adopt, operationalise, and secure them before strategic competitors gain asymmetric advantages. This article argues that NATO must pursue a two-track approach: first, fostering quantum innovation, experimentation, and operational adoption across the Alliance; and second, protecting its technological edge, supply chains, critical infrastructure, and security interests against emerging quantum-enabled threats. Achieving a quantum-ready Alliance will require close cooperation among Allies, industry, academia, and NATO entities to translate technological progress into secure and operationally relevant capabilities.
