China Reports Mass Production of Dilution Refrigerators; Is a Global He-3 Shortfall Coming?

Key TakeawaysChina has reported a milestone in quantum-computing infrastructure: mass production of a domestically developed dilution refrigerator for superconducting quantum chips. In superconducting quantum computing, dilution refrigerators are core enabling hardware as they provide ultra-low-temperature environments near absolute zero—on the order of ~10 millikelvin (mK)—to suppress thermal noise and to help stabilize qubit operation (10 mK is roughly the ultra-cold temperature superconducting qubits need). A U.S. government procurement specification for dilution refrigeration systems, for example, treats “10 mK or below” as a baseline target for these platforms.In public reporting, China’s mass-production claim is associated with the “EZ-Q Fridge,” developed by the Anhui Quantum Computing Engineering Research Center in collaboration with QuantumCTek.A Global Times report describes the EZ-Q Fridge as having “rapid and stable cooling capability,” and says deliveries began in the second quarter of 2023 after successful trials. The same report quotes the project lead saying the system can operate in a low-noise environment “as low as 10 mK.”The report also frames the achievement in the context of supply constraints, stating the leading manufacturers have been based in Finland, the UK, and the US, and that exports of components to China have been restricted. This point is presented as an interviewee characterization within the article rather than as an independently documented market survey.Beyond media reporting, performance claims are more defensible when tied to vendor-published specifications.QuantumCTek (ezQ-Fridge-Platform500)QuantumCTek’s English-language product listing for its ezQ-Fridge platform describes a dilution refrigerator engineered for hundred-qubit superconducting quantum computing and emphasizes domestically produced subsystems. The same listing provides concrete parameters including: base temperature ≤10 mK, cooling time ≤32 hours, recovery time ≤15 hours, and cooling capacity at 100 mK ≥500 μW.Origin Quantum (Origin SL1000)Origin Quantum’s SL1000 dilution refrigerator page positions the system as delivering ultra-low temperatures “below 10 mK” and describes applications spanning superconducting quantum computing and condensed-matter research.The Global Times report states the EZ-Q Fridge team has “been participating” in the Zu Chongzhi superconducting quantum computing experiment, and Zu Chongzhi had used Finnish-made dilution refrigerators. Importantly, that is not the same as confirming EZ-Q Fridge has already replaced imported units inside Zu Chongzhi systems. A cautious framing makes clear this indigenous work is part of the broader ecosystem supporting China’s superconducting quantum experiments. It is fair to say Chinese reporting frames mass production as reducing reliance on foreign suppliers and mitigating the effects of restrictions. Dilution refrigerators reach millikelvin temperatures by circulating a helium-3 and helium-4 mixture. Scaling superconducting-quantum deployments likely will translate into real demand for ³He—especially for initial charges when new systems are installed. Vendors publish mixture guidance making this dependency concrete; for example, Bluefors lists XLD1000: 40 L/180 L as its He-3/He-4 ratio, underscoring that ³He is a key consumable input even when systems are designed to recirculate the mixture.On the supply side, the U.S. Department of Energy’s National Isotope Development Center notes DOE’s ³He is a byproduct of tritium decay and is separated during tritium processing, which constrains how quickly supply can scale. Historically, tight supply has been associated with shortage concerns. A Congressional Research Service report describes the helium-3 shortage as acute and affecting federal investments in security and scientific research.Against such a backdrop, if China (or any large market) rapidly expands the installed base of dilution refrigerators, it will likely increase global demand for initial fills and ongoing helium-3 needs. Without new reserves here on Earth or mining from the lunar surface, economic supply-and-demand will cause price volatility—particularly in this relatively small, specialized market. Without additional independent documentation, it is not strictly verifiable from reporting alone that China has fully “broken” reliance across the entire supply chain. A domestically available dilution refrigerator platform—if it meets its claimed parameters—reduces a major bottleneck in superconducting quantum R&D and commercialization. The impact is less about a single component and more about scaling and supply-chain reliability: dilution refrigerators determine how many wiring channels can be supported, how repeatable experiments are, and how quickly systems can be brought online after installation or maintenance.However, two strategic conclusions should be stated with discipline: A MERICS analysis dated October 2, 2025 reports that Origin Quantum was preparing to export its Origin SL400 dilution refrigerator to Belt and Road countries (with examples listed). This supports a narrow claim—preparation to export—but does not, by itself, confirm shipments have occurred, the size of any orders, or sustained export volume.Based on what we know, the takeaway is simple: China-linked reporting reveals the EZ-Q Fridge has moved into mass production, with deliveries starting in Q2 2023 and temperatures claimed down to about 10 millikelvin. Vendor specs from China-based firms also publish practical performance numbers. For example, one QuantumCTek listing says the system can hold a small but meaningful amount of cooling “muscle” at a slightly warmer ultra-cold stage at 100 mK and cool the machine from room temperature to operating conditions in about a day and a half. As more of the refrigerators are deployed, attention will likely shift to the supply of helium-3—the rare isotope used in the He-3 and He-4 mixture making millikelvin cooling possible. With a finite supply of He-3 here on Earth, the demand signal will likely translate into higher costs for building and scaling cryogenic quantum systems. Time will tell.Image: China reportedly mass producing dilution refrigerators; a major driver of He-3 demand, a rare, if not the rarest, gas here on the planet.
