On May 28, 2026, the OECD Council adopted the Recommendation of the Council on Quantum Technologies (OECD/LEGAL/0508), the world's first intergovernmental standard for quantum technologies, marking the official transition of quantum technology governance from "academic discussion" to "institutional construction". At the same time, Academician Pan Jianwei of the Chinese Academy of Sciences warned at the 2026 Future Science Forum that excessive capital enthusiasm and conceptual hype in the quantum information industry are rampant, calling for the establishment of a national-level technology evaluation mechanism and industry access standards. The disruptive impact of quantum computing on existing encryption systems, the geopolitical implications of quantum communication, and the military applications of quantum sensing have made quantum technology a new frontier in great power competition. Based on the eight-dimensional framework of Prim-Lex Theory (Economic Climatology), this paper introduces, for the first time, quantum technology governance into the mathematical expression of a complexified unified field. From Prim-Unity·Prim-Fire (quantum computing energy consumption and qubit coherence time) to Eight Trigrams·Eight Information (entropy governance of quantum information networks), it constructs a quantitative assessment system for quantum technology governance dimension by dimension. Using three empirical anchors——the US-China-Europe quantum competition, post-quantum cryptography (PQC) standardization and migration, and the quantum-safe encryption standards debate——this paper demonstrates the application pathway of the eight-dimensional framework in identifying "phase differences" and "critical windows" in quantum governance, providing a quantifiable, programmable, and auditable mathematical language and governance tool for the transition of global quantum technology from "technological competition" to "sustainable governance."

Quantum technologies are rapidly moving from laboratory research toward industrialization, commercialization, and capital formation, while introducing new sources of financial risk associated with technological uncertainty, cybersecurity and post-quantum cryptography (PQC) migration, regulatory change, supply-chain resilience, and investment timing. In 2024, the U.S. National Institute of Standards and Technology (NIST) finalized and published three foundational PQC standards, FIPS 203, FIPS 204, and FIPS 205. In 2025, the Bank for International Settlements (BIS) advanced Project Leap to test quantum-safe cryptography in financial infrastructure, while the OECD published its A Quantum Technologies Policy Primer. In 2026, the Hong Kong Monetary Authority (HKMA) introduced the first Quantum Preparedness Index (QPI), with an initial sector-level score of 2.3 out of 10, indicating that quantum preparedness in the banking sector remains at an early stage. These developments highlight a growing need to integrate technological, cybersecurity, institutional, and financial-risk perspectives within a coherent decision architecture. This paper develops a Prim-Lex Quantum Finance framework based on Prim-Lex Theory (Economic Climatology), integrating five Prim-Fires, eight-dimensional coherence, and Nine-Nexus guidance. The Five Prim-Fires comprise Technological-Capability Prim-Fire, Security-Resilience Prim-Fire, Institutional-Governance Prim-Fire, Industrial-Commercial Prim-Fire, and Earth-System Intelligence-Coherence Prim-Fire. The Prim-Lex Eight-Dimensional Quantum Finance State Space (PL-8D-QF) characterizes quantum-technology investment projects across eight dimensions: Technological Capability; Security and Quantum Readiness; Policy and Regulatory Alignment; Technology Maturity and Lifecycle; Ex-ante Financial Viability; Supply-Chain and Systemic Resilience; Temporal Synchronization and Transition Readiness; and Information Quality and Transparency. Building on this state space, the paper introduces the Quantum Investment Coherence Index (QICI), which combines a weighted geometric aggregation of eight-dimensional state strengths with a Kuramoto-based coherence measure derived from dynamic phase information extracted using the Hilbert transform. The central testable proposition is that multidimensional coherence contains incremental predictive information about financial risk beyond the information contained in dimension strengths alone. The framework further specifies a quantitative transmission mechanism from QICI to Probability of Default (PD), Expected Loss (EL), risk-adjusted returns, and financing costs or credit spreads, while distinguishing the Quantum Sovereignty Index (QSI) for national strategic assessment from QICI for project- and investment-level decision-making. The paper formulates 12 testable hypotheses and develops an empirical validation design incorporating panel data, predictive modeling, data-driven critical phase-threshold identification, block bootstrap procedures, out-of-sample validation, and falsification or placebo tests. The critical phase threshold is not imposed ex ante as a universal constant, such as , but is identified from predictive performance in the data; is retained only as a falsifiable theoretical benchmark. The framework then links QICI to risk pricing, investment timing, capital allocation, risk mitigation, and exit decisions, thereby establishing a decision chain from quantum-technology state assessment to financial-risk pricing and capital allocation. The paper seeks to extend the assessment of quantum technologies from technological evaluation to financial evaluation and from compliance-oriented assessment to risk-sensitive allocation optimization. It provides a quantifiable, testable, programmable, and auditable analytical framework for quantum-technology investment, institutional quantum preparedness, post-quantum cryptography migration, and emerging quantum-climate-finance research.
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.
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.
Abstract: Quantum computing poses a structural challenge to contemporary cryptographic infrastructures that underpin digital governance, financial systems, and cross-border data flows. As quantum capabilities advance, widely deployed encryption standards risk obsolescence, exposing systemic vulnerabilities within cloud architectures, blockchain ecosystems, and global data protection regimes. This paper critically explores the convergence of Quantum Computing, Post- Quantum Cryptography (PQC) and international regulatory frameworks. It analyses the preparedness of key jurisdictions such as the European Union, the United States, Japan, China and Singapore, in embedding quantum-resilient standards into cybersecurity and data privacy laws. The paper proposes prospective strategies for building harmonized governance mechanisms and developing agile regulatory mechanisms that can evolve alongside quantum technological progress. Securing data against quantum threats is not solely a technical imperative but a pressing legal and geopolitical priority in the evolving architecture of digital sovereignty.

Quantum sovereignty—the capacity of a state or polity to develop, deploy, control, and secure quantum technologies and their enabling ecosystems without undue external dependency—has emerged as a central concern of technology governance. Building on the strategic signals of programmes such as the U.S. QuantumEAGLe initiative and on existing digital-sovereignty and post-quantum cryptography (PQC) frameworks, this paper proposes a multi-dimensional Quantum Sovereignty Benchmark Framework (QSBF). The framework comprises six pillars (Cryptographic Resilience, Compute & Hardware Optionality, Supply-Chain Sovereignty, Talent & Knowledge Base, Standards & Normative Influence, and Governance & Institutional Capacity), each populated with measurable indicators and illustrative maturity levels. Pros and cons of the proposed approach are examined, and the framework is systematically compared with NIST PQC standards, European digital/cloud sovereignty instruments, emerging academic treatments of quantum sovereignty, and broader digital-sovereignty indices. The paper concludes that while no single global standard yet exists for quantum sovereignty, a transparent, modular, and graduated set of benchmarks can support self-assessment, peer learning, and more equitable international dialogue.
