Washington has banned the export of cryostats and laser components to China to slow its quantum computing rise. Chinese manufacturers have localized their supply chain and continue to advance. Behind this reversal, a durable technological bifurcation is emerging: three parallel quantum ecosystems—American, Chinese, and European—are taking shape, and their fragmentation is slowing global innovation at the precise moment when the technology is beginning to produce concrete results.

The Essentials

  • American export controls have stimulated the localization of China’s quantum supply chain, accelerating the autonomy they aimed to block.
  • China is investing approximately 15 billion dollars in quantum computing, and the 15th Five-Year Plan (2026-2030) should increase these allocations (The Quantum Insider, 2026).
  • Chinese actors such as Origin Quantum, SpinQ, and QuantumCTek now cover segments ranging from superconducting processors to cryogenic equipment and quantum communications.
  • Europe has one billion euros over ten years through the Quantum Flagship (2018-2028), creating a 15-to-1 asymmetry against China that forces a still-undefined choice of technological alignment.
  • The open question is whether three compartmentalized ecosystems will produce a parallel race toward excellence or costly duplication that slows everyone down.

Export Controls as an Unintended Lever of Industrial Policy

The history of technological sanctions harbors a recurring irony: attempting to block a technology can accelerate its local mastery. American restrictions on advanced semiconductors, analyzed here in the battle over semiconductors against the backdrop of massive public subsidies, offered a first example. The quantum sector reproduces the mechanism, with added intensity.

American controls on quantum technologies targeted specific components: cryostats operating at temperatures near absolute zero, high-coherence lasers used to manipulate qubits, low-noise control electronics. These devices form the material substrate of superconducting quantum computing, the dominant technology at IBM, Google, and their Chinese equivalents. Without access to American and European suppliers, the expected logic was a significant slowdown of the Chinese program.

The logic worked, but in the wrong direction for Washington. Faced with supply restrictions, Chinese companies mobilized substantial available public financing to internalize the manufacturing of these components. Origin Quantum, based in Hefei, which develops superconducting processors, has vertically integrated part of its chain. SpinQ, specializing in nuclear spin-based quantum systems, did the same in its segment. The supplier ecosystem that formed around these companies now represents an industrial capacity that export controls precisely helped create.

This mechanism deserves to be named clearly: a restriction on market access, when applied to an economy with sufficient financial and human resources, acts as a productive constraint. It forces internalization that the market would not have spontaneously produced because importing was faster and cheaper. The lag effect exists, skill advancement takes time, but the technological anchoring effect that results is often deeper than what a dependence on foreign suppliers would have permitted.

15 Billion Against 1 Billion: The Asymmetry of Ambitions

Investment figures tell a simple story. China is dedicating approximately 15 billion dollars to quantum computing, according to The Quantum Insider. The European Union has committed 1 billion euros over ten years to its Quantum Flagship, a program launched in 2018 running through 2028. The United States, for its part, finances through the National Quantum Initiative Act and programs from DARPA, the DOE, and the NSF, significant amounts dispersed among federal agencies, states, and private companies.

The crude 15-to-1 ratio between Chinese and European ambitions warrants a double caution. First, public investment figures do not translate linearly into technological capacity: allocation efficiency, the quality of research institutions, and the density of private ecosystems matter as much as committed amounts. Europe has first-rate universities and research centers—Delft, Munich, Oxford, Paris—whose scientific output remains competitive. Second, Chinese investment is partially opaque: the 15 billion aggregates commitments from central government, provincial governments, and companies whose perimeters overlap.

That said, the asymmetry of ambitions is real. The Chinese 15th Five-Year Plan (2026-2030), whose broad outlines are emerging, should, according to analysts, substantially increase these allocations. China treats quantum as a first-rank strategic domain, on the same level as semiconductors or artificial intelligence, a reading that the article on European limited sovereignty illuminates in its industrial dimension.

The three programs differ in nature. The Chinese program is a state project driven by an explicit political will for technological self-sufficiency. The European program is a scientific coordination initiative: ambitious for a multinational academic initiative, modest for an industrial power strategy. The American model relies on private companies—IBM, Google Quantum AI, IonQ—supported by federal financing, whose agenda is commercial before being geopolitical.

A Chinese Ecosystem That Now Covers the Entire Stack

One of the most concrete results of the decade of massive investment and five years of export control pressure is the constitution of a Chinese quantum ecosystem that now covers the entire technology stack, from hardware components to software applications.

Origin Quantum, founded in 2017 in Hefei by researchers from the University of Science and Technology of China, has become the spearhead of superconducting processors. The company has deployed systems accessible via cloud and is working on error correction architectures, the main technical challenge separating current machines from a fault-tolerant quantum computer. SpinQ markets compact quantum systems based on nuclear magnetic resonance, with a range extending from educational devices to research machines. QuantumCTek, listed on the Shanghai exchange since 2020, occupies a distinct but strategic segment: quantum communication and quantum key distribution for cryptography.

This diversity is not anecdotal. It reflects a deliberate strategy of covering different technological platforms—superconductors, photonics, trapped ions, spins—without betting on a single horse in a race whose winner no one yet knows. American companies do the same, but within a private competitive framework. The difference is that Chinese companies operate within national planning that coordinates efforts rather than allowing them to duplicate freely.

The question of these systems’ quality compared to American leaders remains open. Chinese scientific publications in the quantum domain have grown in volume and citation. Work such as photon-based processors has sparked international debate about their real scope. The gap in coherent qubits and error rates remains significant compared to the best machines from IBM or Google, but it is narrowing.

The European Dilemma That Bifurcation Renders Urgent

Michel Duclos, in his analysis of European strategic autonomy, identifies triple pressure on the liberal West: Russian escalation, American disengagement, and global South ambiguity. This pressure forces Europe to choose between the American orbit and constructed autonomy. The quantum domain reproduces this dilemma with directness applicable to the technological field.

Remaining in the American orbit regarding quantum means accessing the best available machines—IBM, Google, Amazon Braket, Microsoft Azure Quantum—and benefiting from research from the East Coast ecosystem and the Bay Area. The cost of this option is growing dependence in a domain where export controls may one day play in reverse: an American partner controlling access to critical quantum capabilities possesses leverage over European industries and institutions that depend on them.

Building autonomy through the Quantum Flagship means investing massively in proprietary capacities, at the risk of accumulating delay relative to current leaders. Europe has real assets: excellent academic groups at Delft (photonics), Innsbruck (trapped ions), Munich and Paris, an industrial base in cryogenics (Air Liquide, Bluefors) and electronics. But moving from academic research to competitive quantum industry requires a scale break that the Flagship’s one billion euros alone cannot finance.

A competing reading, one that economists like Philippe Aghion, working on Schumpeterian innovation, might advance, suggests that the pertinent European response may not be to entirely reproduce the American or Chinese technology stack, but to target segments where Europe has authentic comparative advantage—secure quantum communication for its institutions, quantum metrology for its precision industry, certain aspects of quantum simulation for its chemistry and materials. A strategy of selective integration rather than a frontal race.

This reading has coherence. But it assumes Europe accepts a residual form of dependence on the segments it does not master, and that this dependence remains controllable. In a world where export controls have become a common instrument of foreign policy, as the trajectory of China in green textiles also demonstrates, this wager deserves to be made with open eyes.

Three Compartmentalized Ecosystems: Gain or Loss for Global Science

Fragmentation into three distinct technological blocs carries a cost to the pace of global innovation that strategists still insufficiently evaluate.

The history of sciences and technologies offers precedents in both directions. The Cold War produced a technological race whose results in space, nuclear, and computing were spectacular. Competition between separate ecosystems can stimulate effort and produce breakthroughs that a technological monopoly would not have generated. The argument has real validity.

But quantum physics is a discipline where international collaboration has historically been productive. Exchanges between American, European, Australian, Japanese, and even Chinese laboratories accelerated collective progress over the past twenty years. Quantum error correction, the main current technical obstacle, is a problem where theoretical advances by one group benefit all. Compartmentalization slows this diffusion.

The duplication of supply chains also represents a concrete economic cost. Developing an autonomous Chinese cryogenic industry, independent laser capacities, local control electronics—all this mobilizes resources that, in a world without export controls, could have been concentrated on layers of the stack where each economy has comparative advantage. The collective efficiency of the sector decreases when each bloc must duplicate the same foundations.

This cost does not invalidate American export control logic, which responds to legitimate national security concerns in a domain with potential military implications—cryptography, materials simulation for weapons, optimization of complex systems. But it requires acknowledging that bifurcation has a price, and that this price is collective.

The Coming Years Will Test the Models

The decade 2030-2040 should allow testing several hypotheses that remain open today.

The first uncertainty concerns the technical resilience of China’s quantum ecosystem to frontal competition. Components and systems developed under import substitution pressure must demonstrate their competitiveness outside the captive market that China represents. The answer will determine whether forced localization has produced a real industry or a protected one. Chinese exports of quantum systems to third countries, particularly within the Global South, will constitute a concrete signal. SpinQ is already commercializing systems in several Southeast Asian and Latin American countries: their success in these markets will provide an external measure of competitiveness.

The second hypothesis concerns the critical technological threshold: when, if ever, a fault-tolerant quantum computer becomes operational for practical applications. IBM, Google, and their Chinese equivalents are all working on quantum error correction. The group that crosses this threshold first will possess considerable advantage for cryptographic and simulation applications. If this crossing occurs within a compartmentalized ecosystem, access to corresponding capacities will be geopolitically conditioned, with implications for data sovereignty, communications security, and industrial capabilities of third countries.

The third hypothesis is European. The Quantum Flagship reaches conclusion in 2028. Its continuation, the modalities of a second-generation program, committed amounts, and chosen governance will indicate whether Europe has learned the lessons of current asymmetry. A signal to monitor closely is European capacity to make the leap from academic research to industrial-scale quantum companies, a transition that neither France, nor Germany, nor the Netherlands has yet successfully accomplished at the same level as IBM or Google.

The stakes exceed quantum technology alone. Quantum is an early indicator of a pattern that will structure the global technological economy: fragmentation of technological value chains into geopolitical blocs, transformation of standards into weapons, conversion of dependencies into levers. Europe has already passed through this awareness in semiconductors. Quantum offers it the chance to decide its positioning before power dynamics are entirely locked in.
