Executive Summary
Australia, India, Singapore, Japan, South Korea, and Taiwan all now treat quantum technology as a strategic capability tied to industrial policy, national security, and digital sovereignty, while China is widely assessed as pursuing the largest state-backed quantum push among the seven jurisdictions reviewed. Across these strategies, the common pattern is a shift from pure research support toward ecosystem building: national roadmaps, dedicated coordination bodies, testbeds, talent pipelines, commercialization programs, and security-sensitive applications such as post-quantum cryptography, secure communications, sensing, and critical infrastructure resilience.
The main differences are scale, governance maturity, and geopolitical alignment. Australia explicitly links quantum to critical technologies policy and to allied frameworks including AUKUS and the Quad. India frames quantum as a mission program with four thematic hubs and concrete deliverables in computing, communications, sensing, and materials. Singapore uses a tightly governed five-year strategy led by the National Quantum Office and National Quantum Steering Committee. Japan emphasizes long-horizon roadmap governance through the Cabinet Office and Integrated Innovation Strategy structures, with milestones extending to 2040. South Korea and Taiwan both combine national strategy with industrial-scale ecosystem development and strong state coordination.
Country Findings
Australia
Australia's National Quantum Strategy presents quantum as both an economic growth sector and a national-interest capability. The strategy says the government will invest in, connect and grow Australian quantum research and industry; drive commercialisation; create investment pipelines through the National Reconstruction Fund; support new infrastructure; attract global talent; strengthen international partnerships; and champion responsible innovation that safeguards national interests. Supporting government material says Australia has already announced an estimated $1.4 billion in quantum-related support over more than two decades, giving the strategy a base of prior public investment rather than a blank-slate launch.
For sovereign-intelligence purposes, Australia matters because quantum policy is being folded into critical technologies, defence-adjacent capability, and trusted-partner frameworks. The strategy's emphasis on infrastructure audits, supply-chain access, commercial pathways, and international influence aligns with AUKUS and Quad-era thinking about resilient advanced-technology ecosystems, even where those alliances are not the sole delivery vehicle. The main policy signal is that Australia is trying to move from research strength to controlled commercialization while preserving strategic autonomy in sensitive applications.
China
OECD's 2025 review identifies China as the largest public investor in quantum technologies among major jurisdictions surveyed, at about EUR 14.6 billion. That scale places China in a distinct category and suggests a state-led approach built around long-horizon industrial planning, strategic infrastructure, and dual-use capability development rather than only civil innovation policy. The same OECD review groups quantum strategies around research leadership, infrastructure, talent, commercialization, and security, and China is consistently treated as a front-rank actor across those dimensions.
For sovereign-intelligence use, the key issue is not just spending size but strategic intent. China's quantum posture has implications for secure communications, sensing, cryptography disruption, and competition over standards and supply chains. Even where official English strategy documents are less accessible than in other jurisdictions, OECD's comparative assessment is sufficient to establish China as the benchmark competitor shaping the security logic of Australian, Japanese, Korean, Taiwanese, Indian, and Singaporean quantum policy.
India
India's National Quantum Mission is among the clearest mission-structured programs in the region. The Union Cabinet approved the mission at Rs. 6003.65 crore for 2023-24 to 2030-31 to seed, nurture, and scale scientific and industrial R&D and create a national quantum ecosystem. The mission sets concrete technical ambitions: intermediate-scale quantum computers with 50-1000 physical qubits in eight years, satellite-based secure quantum communications over 2000 kilometers, inter-city QKD over 2000 kilometers, multi-node quantum networks with memories, high-sensitivity magnetometers, atomic clocks, and quantum materials and device development.
India's governance model is also explicit. The Department of Science and Technology runs the mission, supported by a Quantum Technology Cell and four Thematic Hubs covering quantum computing, communication, sensing and metrology, and materials and devices. That matters because it gives India an operational architecture for procurement, startup support, curriculum development, and international secure-communications cooperation. For the Library, India is a strong example of how a sovereign quantum strategy can combine industrial policy, technical milestones, workforce creation, and security-oriented communications infrastructure.
South Korea
South Korea's National Quantum Strategy aims to make the country a leading player in the global quantum economy by 2035. Public summaries indicate more than KRW 3 trillion in public-private investment through 2035, alongside priorities around talent, quantum materials and equipment, ecosystem formation, and technology alliances. Additional reporting on Korea's policy direction points to a thousand-qubit ambition and explicit interest in post-quantum infrastructure and commercialization pathways.
For sovereign intelligence, South Korea's importance comes from the fusion of state coordination and industrial capability. Korea is not pursuing quantum as a narrow lab agenda; it is tying it to semiconductors, communications, manufacturing ecosystems, and allied tech positioning. That makes Korea particularly relevant for tracking future export controls, trusted-supply-chain arrangements, and standards competition in the broader Indo-Pacific advanced-technology order.
Singapore
Singapore's National Quantum Strategy is unusually clear in structure and governance. It commits close to S$300 million over five years and is run by the National Quantum Office, hosted by A*STAR and supported by the National Research Foundation, under guidance from the National Quantum Steering Committee. The four strategic thrusts are scientific excellence, engineering capabilities, talent, and innovation and enterprise partnerships. A flagship initiative under the strategy is the National Quantum Processor Initiative, which aims to build local capability to design and build practical quantum processors, initially focusing on trapped ions, neutral atoms, photonics, and control electronics.
Singapore's model is relevant because it treats sovereign capability as selective depth rather than maximum scale. The strategy emphasizes trusted coordination, talent concentration, and translational engineering, which is consistent with Singapore's broader statecraft in semiconductors, AI, cyber, and digital infrastructure. In security terms, local processor design capability, talent retention, and close coordination between research, government, and enterprise strengthen resilience even without the huge budgets seen in China or the broader industrial bases of Japan and Korea.
Japan
Japan's quantum policy is built around Cabinet Office-led roadmap governance rather than a single headline spending law. Official government material points to the Quantum Technology Innovation Strategy Roadmap and the 2022 Vision of Quantum Future Society. The roadmap lays out milestones from 2020 to 2040 across quantum computing, sensing, and communications, including targets around scalable systems by 2030 and more advanced fault-tolerant capabilities by 2040. Government communication also frames quantum as part of a broader innovation and societal transformation agenda.
Japan matters to the sovereign-intelligence Library because it connects long-range technical planning with ecosystem building, standards, and alliance-compatible industrialization. Even where publicly accessible English material is thinner than for Australia or Singapore, the policy direction is clear: Japan seeks compute sovereignty, secure communications capability, and a globally relevant industrial ecosystem anchored in state coordination and major corporate research capacity.
Taiwan
Taiwan's quantum push is centered on the National Science and Technology Council, the National Quantum Team, and the Taiwan Quantum Program Office. Public material describes an NT$8 billion five-year program launched in 2022, with NSTC working alongside Academia Sinica and the Ministry of Economic Affairs to integrate government, research, and industry resources. Trade-oriented official summaries describe quantum as a strategic national priority and emphasize semiconductor-linked advantages, public-private coordination, and supply-chain development.
For sovereign intelligence, Taiwan's significance is straightforward: it is trying to convert semiconductor ecosystem strength into a foothold in quantum hardware, systems, and hybrid quantum-AI infrastructure. That gives its quantum policy unusually high geopolitical weight relative to budget size because any Taiwanese role in future quantum supply chains intersects with the broader contest over trusted chip fabrication, industrial resilience, and strategic technology dependency.
Strategic Patterns
Three cross-cutting patterns stand out. First, all seven jurisdictions are converging on a model that treats quantum as critical infrastructure-in-waiting, not just frontier science. Second, governance is becoming more centralized: national mission offices, steering committees, roadmap councils, and thematic hubs are replacing diffuse grant-only systems. Third, security implications are no longer implicit; they are visible in secure communications goals, post-quantum migration planning, trusted supply-chain language, and alliance-based technology cooperation.
The main divergence is scale and delivery model. China leads in raw public investment, Australia and Singapore are highly legible in policy design, India is unusually concrete in mission outputs, Japan is the most roadmap-oriented, and South Korea and Taiwan are especially important where quantum strategy intersects with semiconductor and electronics ecosystems.
Library Implications
For a sovereign intelligence library, the highest-value monitoring categories are: national budget changes, dedicated governance bodies, mission-level technical targets, post-quantum security migration, export-control spillovers, allied research partnerships, and the emergence of trusted quantum supply chains. Australia, India, Singapore, Japan, South Korea, and Taiwan all provide sufficiently structured public material to support recurring watchlists; China requires heavier use of comparative institutional sources such as OECD to normalize official opacity.
In practical terms, these strategies should be tagged not only under quantum technology but also under defence-adjacent capability, critical technologies, secure communications, post-quantum cryptography, semiconductor sovereignty, and alliance industrial policy.
