This chapter explores the transformative effect of quantum technologies in the European Union (EU), emphasising their impact on digital sovereignty and drawing conclusions from the securitisation process. Moreover, the chapter offers a historical overview of quantum-related policy in the EU, distinguishing three phases: inception (2016–2018), consolidation (2019–2022), and strategic awakening (2023-present). The analysis discusses how the EU’s engagement with quantum technologies has been shaped by internal political dynamics and strategic needs, leading to increased public investment and initiatives aimed at harnessing and securing these technologies.

Over the past decades, a gradual technological marginalisation of Europe could be observed, as it became dependent on imports of advanced microchips from the United States and Taiwan. However, despite planned investments in the development and production of semiconductors in the EU Member States, Europe is still unlikely to be able to compete with the United States and China in this area. The solution to this problem may lie within quantum technology, the economic use of which is in the initial phase in all world centres. The performance of quantum computing surpasses algorithms used in silicon technology by several tens of orders of magnitude. This means that access to quantum technology will become a basic determinant of security in the coming years. The aim of this paper is to present the issue of quantum technology and its most important implicationsin the context of the technological sovereignty of the European Union.
In the era of digital transformation quantum technologies represent a new challenge for the society, industries, governmental sector. The benefits and consequences of the adoption of quantum technologies have yet to be fully explored. In this context the role these technologies will play in urban context is essential to explore. The present study examines the European Union’s quantum initiatives and its vision of the possible applications of quantum solutions. This study applies these considerations to the European urban context and explores it through the prism of public values created by the smart cities and smart city dimensions. The findings of this research highlight the socio-technical implications and transformative potential of quantum technologies on European smart urban environments and offer strategic insights for urban planners, policymakers, and city managers to prepare for the opportunities presented by quantum technologies.
Quantum cybersecurity has emerged as a critical strategic issue at the intersection of national security, technological advancement, and digital sovereignty. As quantum computing technology advances toward practical implementation, the dual-edged nature of this revolutionary technology becomes increasingly apparent: while quantum computers threaten to break traditional encryption methods like RSA and ECC, they simultaneously promise to enable quantum-resistant algorithms through post-quantum cryptography (PQC). This comprehensive analysis examines the current state of quantum cybersecurity threats, the global investment landscape in quantum technologies, the vulnerability of critical sectors, and the urgent need for proactive migration to quantum-safe solutions. With NIST’s finalization of post-quantum cryptography standards in 2024 and projected quantum threats materializing by 2030, organizations across defense, finance, healthcare, and critical infrastructure must accelerate their transition to quantum-resistant technologies. The geopolitical implications are profound, with China, the United States, and European Union engaging in an unprecedented quantum arms race that will determine future cybersecurity leadership and technological sovereignty.
Abstract Quantum computing research and development efforts have grown dramatically over the past decades, led in part by initiatives from governments around the world. Government quantum computing investments are often driven by national security or digital sovereignty concerns, with the language used depending on the geography involved. For example, a focus on “national security” and quantum computing is prominent in the USA, while European countries regularly focus on “digital sovereignty”. These phrases are often loosely defined and open to interpretation, and they share some common motivations and characteristics (but also have important differences). This paper identifies specific governmental entities typifying the national security/digital sovereignty perspectives, along with these organisations’ respective roles within national and international policy engagement in quantum computing. It analyses governmental structures, historical developments and cultural characteristics that contributed to this national security–digital sovereignty divide. Building on this analysis, we use the history of other technologies to illustrate how we might adapt tested policy approaches to modern political dynamics and to quantum computing specifically. We frame these policy approaches so that they do not overemphasise “digital sovereignty” or “national security”, but rather address interests shared across both concepts, with a view to facilitating international collaboration.
This research delves into the nexus between quantum technologies and their prospective role in enhancing secure satellite communications, with a particular focus within the European Union (EU) space security and defence. Embarking on an interpretivist research design, the study employs qualitative content analysis and fieldwork at the European Union Agency for the Space Programme (EUSPA) to elucidate the interplay between quantum principles and the EU's space endeavours. Through an exploration of quantum key distribution via space, the research shows a promising future for the secure transmission of critical data. To harness these quantum advancements effectively, substantial investments within the EU are essential. Against the backdrop of the evolving EU space strategy for security and defence, the research contemplates the centralisation of space matters within a singular, specialized EU body. In the broader context, the study underscores the urgency for international regulations to navigate the burgeoning complexities of space technology advancements and to safeguard against the threats of space weaponization. As the EU navigates unexplored space areas, the combination of quantum innovation, strategic coherence, and international cooperation emerges as crucial in guiding the EU towards a strong...
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.
