Quantum science and technology is a key cross-cutting scientific field of the twenty-first century, with a significant influence on critical societal challenges including climate change, energy, and more. The impact of technologies such as quantum computers, quantum sensors, and quantum communication systems is generally expected to become at least as dramatic as the inventions of semiconductors, transistors, lasers, and nuclear energy. By framing the quantum transformation of electric systems as a socio-technical challenge and acknowledging the intertwined nature of technology innovation with sociocultural, political, and economic factors, this chapter discusses the contextual specificities and techno-organisational infrastructures required for this transformation. The chapter pays special attention to the potential of quantum sensing for decentralising infrastructures, governance, and organisational structures and offers research directions to address the unprecedented challenges and opportunities presented by the quantum transformation of electric systems.

Quantum technologies are rapidly emerging as a transformative force with profound implications for critical infrastructures, national security, and global governance. Quantum computing, quantum communications, and quantum sensing promise unprecedented advances in data processing, secure communications, and environmental and infrastructure monitoring. At the same time, their disruptive potential introduces new ethical, security, and geopolitical risks, particularly for systems that underpin modern societies such as energy networks, telecommunications, finance, transportation, and defence infrastructures. This paper examines the governance of quantum technologies for critical infrastructures, moving from ethical impact assessment to the formulation of coherent national strategies. The study argues that the unique characteristics of quantum technologies — including their high degree of complexity, dual-use nature, and capacity to undermine existing cryptographic and security frameworks — require a shift from reactive regulation to anticipatory and responsible governance. Traditional regulatory approaches are insufficient to address the speed, uncertainty, and strategic relevance of quantum innovation. Instead, the paper emphasizes the need to integrate ethical impact assessment, risk analysis, and societal considerations at the earliest stages of research, development, and deployment. Ethical governance is presented not as a constraint on innovation, but as a foundational element for ensuring trust, resilience, and long-term sustainability. The analysis situates quantum governance within a broader geopolitical context, highlighting how major global actors are investing in quantum capabilities as strategic assets. This competition increases the urgency for coordinated governance frameworks that balance technological sovereignty, security, and international cooperation. Particular attention is given to the protection of critical infrastructures and the transition towards quantum-safe systems, especially in the field of cybersecurity and secure communications. Finally, the paper outlines the implications for national and European strategies, stressing the importance of multi-level governance involving governments, international organisations, industry, and research institutions. It concludes that only a holistic approach — combining ethical foresight, anticipatory governance, and strategic planning — can ensure that quantum technologies enhance societal resilience and security rather than exacerbate systemic vulnerabilities. In this sense, quantum governance becomes a central component of future national strategies for critical infrastructure protection and technological leadership.
Over the past century, quantum theory has taken flight from conceptual breakthroughs, such as wave–particle duality, quantisation of energy, and the uncertainty principle, to practical tools that are the backbone of modern electronics, lasers, semiconductors, and precision measurement systems.

The rapid development of quantum computing is one of the most transformative technological developments of the twenty-first century with profound implications for cybersecurity, digital governance and the future of secure communication systems. Traditional cryptographic infrastructures have fundamentally underpinned digital trust in banking, healthcare, defense, cloud computing, and global communication networks, but the advent of quantum computational power has led to increasing concern about the future of existing standards for encryption. This qualitative study critically examines the changing relationship between quantum computing and post-quantum cryptography through an analysis of the technological, institutional, ethical and governance challenges in the transition to quantum-secure digital systems. The study adopts an interpretivist and exploratory qualitative orientation that aims to understand how governments, cybersecurity experts, technology institutions and policy frameworks are responding to the disruptive potential of quantum technologies. Data were collected using thematic analysis of academic literature, cybersecurity policy documents, archival technological reviews, expert commentaries, institutional reports, and emerging case studies related to the development of quantum-resistant cryptography. The results show that quantum computing presents serious threats to existing public-key cryptographic systems, especially in terms of theoretical abilities of Shor’s algorithm and future quantum decryption models. Meanwhile, the paper outlines post-quantum cryptography as a vital avenue for safeguarding digital privacy, institutional credibility, and cybersecurity robustness in an ever more networked society. The analysis also points to ongoing challenges around technological readiness, regulatory uncertainty, global standardization, resource inequality and ethical issues around surveillance, privacy and digital sovereignty. Yet, the research points to the potential for secure digital transformation, resilient cybersecurity governance, and the re-inventing of future communication infrastructure through post-quantum innovation. The research finds that the transition to quantum-secure systems is not just a technological challenge, but a multidimensional governance and policy challenge requiring international cooperation, ethical foresight and proactive institutional change.
Quantum computing, leveraging the principles of quantum mechanics, is emerging as one of the most transformative technologies of the 21st century, promising computational power that can tackle problems once considered unsolvable. Unlike classical computing, which processes data in bits, quantum computing operates using quantum bits or ‘qubits’ that exploit quantum superposition and entanglement, enabling vastly superior processing power. This paper examines the challenges and opportunities presented by quantum computing, focusing on its potential to transform various industries such as healthcare, finance, education, defence, utilities and more. Additionally, the paper explores its environmental implications and impact on sustainability. A literature survey of key research contributions and a discussion of commercial timelines highlight the current state and future of this revolutionary technology. While quantum computing presents immense opportunities, its technical and economic challenges must be overcome for it to reach widespread commercial adoption. The paper concludes with an exploration of the road ahead for this nascent technology. Despite significant challenges, quantum computing offers unprecedented opportunities to transform multiple sectors, making it an essential area for ongoing research.
