Taiwan is, to most of the tech world, a semiconductor story, and Taiwan Semiconductor Manufacturing Company (TSMC) is the reason why. As the world’s largest contract chipmaker, TSMC makes the overwhelming majority of the most advanced chips, the silicon behind modern computing, AI and defence electronics. In April 2026, Minister of Economic Affairs Kung Ming-hsin launched a Quantum Industry Technology Promotion Office, arguing that quantum will be the next wave of innovation after AI and setting the goal of turning Taiwan from a “silicon island” into a “quantum island”. The framing rests on a genuine claim: Taiwan is not starting from zero, because qubit fabrication, advanced packaging and system integration draw on strengths it already has.

The question is whether semiconductor dominance transfers into a comparable position in quantum, and in which role. Three futures are open: the foundry of the quantum era, fabricating chips designed elsewhere; a supplier of components and subsystems; or a hardware incumbent in its own right. Which one arrives will be shaped as much by choices inside hardware companies internationally as by anything Taipei decides.

Building A Base Before The Window Closes

Taiwan’s quantum programme is older than its recent announcements suggest. A first dedicated funding line known as the Quantum Computing Project arrived in 2018, a Taiwan Quantum Program Office followed in 2021, and in March 2022 the government assembled a National Quantum Team backed by NT$8 billion (US$259 million) over five years. The results are tangible despite still being early. Academia Sinica, Taiwan’s national research academy, built and unveiled the island’s first indigenously designed five-qubit superconducting computer in early 2024, and the programme’s first phase produced superconducting qubit chips, silicon-based spin qubits and the cryogenic control modules around them. In March 2026 the National Science and Technology Council unveiled a second phase aimed at fault-tolerant hardware, a subsystem verification platform in the north and a high-performance computing centre in the south.

A closer look at the funding complicates the headline. The NT$8 billion was never a single appropriation but a cross-government envelope spread across the science council, the economic affairs ministry and Academia Sinica, of which the reviewed council programme is roughly NT$2.45 billion ($76 million USD). The larger obstacle has been political. The central government budget spent much of the first quarter deadlocked in a legislature where an opposition majority withheld review over pay and wider fiscal disputes rather than science. Under Taiwan’s Budget Act, existing projects could continue at previously authorised levels, but new programmes and capital expenditure faced restrictions. The NSTC’s planned quantum classical-hybrid system therefore faced potential budgetary disruption,  although no confirmed delay has been disclosed. The northern subsystem validation platform opened in March, while the proposed southern hybrid system remained at the supplier information gathering stage. For a programme whose entire logic is speed, the effect of a lost quarter would be more than a rounding error in the perspective of a global quantum race.

Two Ways to Build Quantum Chips, Only One Fits Taiwan

Taiwan’s foundry model works in classical chips because design and manufacturing separate cleanly, and TSMC can fabricate a processor it did not design. Whether quantum repeats that pattern depends on choices inside hardware companies, not in Taiwan, and the field has started to bifurcate. On one branch sits Silicon Quantum Computing (SQC), a Firgun Ventures portfolio company, which positions single phosphorus atoms in silicon with world-leading 0.13-nanometre precision using a scanning-tunnelling-microscope process of its own, and reported single-qubit fidelities up to 99.99% in Nature in December 2025. That method has no foundry equivalent, so vertical integration was forced on it rather than chosen. On the other branch sit the gate-defined quantum-dot companies, among them Diraq, Quantum Motion (also a Firgun Ventures portfolio company), Quobly, Equal1 and Intel, whose case is that they use existing semiconductor capacity rather than own it. Even here the noise-critical steps, from enriched silicon to control electronics, are being quietly pulled in-house, because iteration speed rewards owning the line. Only one branch leaves room for a merchant foundry at all, hence, which manufacturing model prevails will determine how much of Taiwan’s classical semiconductor playbook survives.

From A Silicon Line To A Quantum Line

The leap from a silicon line to a quantum one is longer than it looks. TSMC’s advantage lies in the world’s most advanced processor chips and advanced packaging, yet silicon-spin qubit developers are adapting industrial 300mm fabs to specialised quantum processes, not simply buying capacity on the latest commercial logic node. Intel makes its Tunnel Falls test chip on a customised 300mm process, Quobly co-designs quantum chips with STMicroelectronics for ST’s 300mm platform, and other silicon-spin developers leverage the likes of GlobalFoundries (Quantum Motion) or imec’s (Diraq) pilot line. What these developers need is bespoke, low-noise flow using enriched silicon-28 and years of cryogenic feedback, low-volume research work a pure-play foundry is typically set up to deprioritise, especially when every wafer slot is worth significantly more to an AI customer today. Despite this, the scarcer constraint is talent rather than tooling, since these quantum computing developers trace back to three decades of physics at institutions such as UNSW, Delft and CEA-Leti, a bench Taiwan’s engineers do not yet match. A quieter chokepoint sits under both branches. Enriched silicon-28 is a narrow supply Taiwan does not make. Given quantum computers fall under US export controls, system assembly happens there, leaving component supply as Taiwan’s most realistic near-term entry point.

Partnerships That Point To A Supply-Chain Role

Taiwan’s partnerships began in 2019 with an IBM Quantum Hub at National Taiwan University, and IBM’s superconducting qubits helped steer Taiwan toward the superconducting modality where it is strongest. Domestic capability has followed, including its first eight-inch superconducting quantum-chip fabrication line. The more recent deals are more telling. SEEQC keeps its core architecture at home while the Industrial Technology Research Institute runs a dedicated line for its control chips and National Taiwan University works with UC Berkeley on interfaces. Rigetti has struck a comparable arrangement with Quanta, each committing more than US$100 million over five years. The pattern is beginning to form where Taiwan supplies manufacturing, packaging and electronics into architectures owned elsewhere, a role its own promotion office approvingly frames as its place in the global quantum supply chain. That is a valuable position, but it is a long way from being the incumbent, and the distinction is the whole point.

What Taiwan Is Building Toward, Three Possible Outcomes

The most probable outcome is that Taiwan may not get to choose its future alone. If the vertically integrated, atom-precision approach scales, fabrication value stays inside the hardware companies, with no wafer contract to win, and the sovereign-manufacturing logic behind DARPA’s benchmarking initiative discourages leaning on a foreign fab. If the fabless branch prevails, Taiwan is better placed, though it would still have to out-compete imec, GlobalFoundries and others arguably already years ahead. A more ambitious forecast has Taiwan build a quantum hardware champion of its own, scaling Academia Sinica’s indigenous machines into a genuine incumbent rather than a supplier to one, though that means competing head-on, from a standing start, with better-funded, better-staffed rivals, and it is the least likely outcome rather than the most.

The likeliest result is the middle path: a deep and well-defended position in components, packaging and control electronics, less than the semiconductor crown but far from a minor supporting role. What should concentrate minds in Taipei is that this outcome is not fully Taiwan’s to choose. Which of those three futures arrives will be settled by decisions taken in laboratories and boardrooms abroad. For a country long accustomed to being indispensable, that is the uncomfortable part, and the reason its quantum strategy could be built around influence over the supply chain rather than command of it.
