Quantum information technology (QIT) encompasses a collection of emerging innovations-quantum computing, quantum communication, and quantum sensing-that leverage unique properties of quantum systems, such as entanglement, superposition, and quantization, in order to process information in ways that are either classically impossible or infeasible. While QIT remains in relative infancy, its potential for unprecedented computational speedups, security of communication, and ultra-precise measurement foreshadows its impacts and risks across economic, strategic, and societal domains. We situate QIT within both its historical and technological context, focusing on the question of what is sui generis or unique about QIT with respect to both technical detail and governance imperatives. We identify how the unique ontological properties of quantum systems may raise novel legal conceptual dilemmas and propose a governance-stack model that aligns potential regulatory instruments with specific layers of the QIT technical stack, enabling precise risk assessment and stakeholder-focused regulation. By adopting an information-theoretic lens, we analyze how QIT's novel affordances-ranging from decryption of classical encryption to ultra-precise sensing-may potentially impact legal domains. Our contribution aims to lay a foundation for understanding QIT's legal implications, offering a framework to navigate its opportunities and risks.

This chapter offers an overview of Quantum Technology Governance : Law & Regulation , highlighting the foundational role of quantum information technology (QIT) and the legal, regulatory, and geopolitical considerations arising from its recent advancements. It maps how quantum computing, communication, and sensing intersect with established legal and governance frameworks across intellectual property, cybersecurity, export controls, and international law. The chapter introduces a progressive analytical structure that begins with QIT’s ontological and governance foundations before turning to domain-specific regulatory considerations and global strategic implications. It synthesizes key themes developed throughout the volume, including adaptive legal interpretation; layered governance mechanisms such as the governance-stack model; mixed intellectual property strategies combining patents, trade secrets, and open innovation; empirical patent trends; EU and US approaches to quantum-enabled cybersecurity risks; the evolution of export control architectures; and the application of effects-based norms in public international law. Across these domains, the chapter identifies a recurring theme of regulatory adaptability. Although QIT introduces non-classical features that stress-test existing legal and policy systems, we argue that many challenges can be met through interpretive flexibility, evidence-based policymaking, and technology governance rather than wholesale doctrinal reform. By integrating legal analysis, empirical insights, and international governance perspectives, the chapter provides policymakers, technologists, scholars, and practitioners with a roadmap for responsible quantum governance as technologies transition from theoretical potential to practical deployment.
Abstract The emergence of quantum information technologies with potential application across diverse industrial, consumer and technical domains has thrown into relief the need for practical approaches to their governance. Technology governance must balance multiple objectives including facilitating technological development while meeting legal requirements, normative expectations and managing risks regarding the use of such technology. In this paper, we articulate a variety of idealised governance models and approaches for synthesising these complementary and sometimes competing objectives. We set out a comparative analysis of quantum governance in the context of existing models of technological governance. Using this approach, we develop an actor-instrument model for quantum governance, denoted the ‘quantum governance stack’, across a governance hierarchy from states and governments through to public and private institutions. Our model sets out key characteristics that quantum governance should exhibit at each level in the stack, including identification of stakeholder rights, interests and obligations impacted by quantum technologies and the appropriate instruments by which such impacts are managed. We argue that quantum governance must be responsive based on (a) the state of technology at the time; (b) resource and economic requirements for its development; and (c) assessments and estimates of the near-term and future impacts of such technology. Our work provides a pragmatic introduction to quantum governance by (a) specifying a taxonomy of governance actors and instruments and (b) providing examples of how different stakeholders within the stack might implement governance responses to quantum information technologies. It is intended for use by stakeholders in government, industry, academia and civil society to help inform their governance response to the quantum technology revolution.
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.

The rapid advancement of quantum computing technology presents unprecedented opportunities and challenges for global governance. This comprehensive study examines the current landscape of international quantum computing regulation, exploring the delicate balance between fostering innovation and addressing security concerns. Through a mixed-methods approach, including policy analysis, expert interviews, and case studies of key countries and regions, we identify significant fragmentation in regulatory approaches, a pressing need for standardization, and ethical considerations that demand immediate attention. Our findings reveal strong stakeholder support for international cooperation, despite geopolitical tensions, and highlight the risk of a growing "quantum divide" between nations. Based on these insights, we propose a series of recommendations, including the establishment of an International Quantum Governance Forum, the adoption of a risk-based adaptive regulatory framework, and the implementation of a Global Quantum Literacy Initiative. This research contributes to the ongoing dialogue on quantum technology governance and provides a roadmap for policymakers, researchers, and industry leaders to navigate the complexities of regulating this transformative technology. By addressing these challenges proactively, we can harness the full potential of quantum computing while mitigating its risks, ultimately shaping a quantum future that benefits all of humanity.
Abstract Quantum computing is rapidly advancing from a theoretical possibility to a transformative force in financial systems. With its high-dimensional computational capacity, quantum technology is promising for enhancing risk modelling, fraud detection and transaction efficiency. However, it also seriously threatens cryptographic security, regulatory coherence and systemic stability. This paper critically analyses the risks introduced by cryptographically relevant quantum computers and assesses the readiness of legal and institutional frameworks to respond. Focusing on the UK financial regulatory environment, the study proposes a quantum-safe integration roadmap grounded in post-quantum cryptography, adaptive regulatory models and sector-wide governance strategies. The paper argues for anticipatory regulation that embeds enforceable standards and strategic collaboration across public and private stakeholders through an interdisciplinary approach combining legal analysis and financial risk modelling. The UK’s leadership in quantum policy positions it to shape international norms in secure quantum adoption. Finally, the paper offers an analytical framework to ensure that quantum innovation reinforces rather than destabilises data integrity, financial resilience and public trust.
