The disruption of the Qatari helium supply resulting from the war in Iran has exposed a structural vulnerability. Beyond helium-4 price volatility, the bigger risk lies in helium-3, which is irreplaceable in the dilution refrigerators that power leading quantum computing architectures. India has no secure, quantified domestic supply of Helium-3. The near-term priority is research support for alternative cooling techniques and shared cryogenic-enabling infrastructure.

Helium spot prices in India surged 70–100 per cent in March 2026 after Iranian drone strikes forced the shutdown of a key LNG processing facility in Qatar, the same infrastructure where Helium is captured as a by-product of natural gas and oil extraction.[1] Currently, Qatar accounts for a third of global helium production and supplies over 50 per cent of India’s helium.[2] Repair timelines mean Qatar’s output is projected to fall 14 per cent over the next five years, compressing global supply precisely when global demand is rising.[3] For India, with no domestic helium production, this is not merely a price shock, it is a structural supply vulnerability with direct consequences for India’s ability to develop and operate quantum technologies.

Helium’s unique chemical and physical properties, such as inertness and high thermal conductivity, make it irreplaceable in semiconductor and optical-fibre manufacturing, drug discovery, leak detection, neutron detectors for nuclear security and weapons detection, and in advanced process tools and medical devices such as MRIs.[4] The helium shortage has already prompted China, Taiwan, South Korea and Japan to seek policy solutions and alternative sources.[5] Tightening supply is creating real constraints on the infrastructure that underpins quantum technology development.[6]

Helium for Quantum: The Two Isotopes

Helium gas is scarce on Earth and difficult to store in gaseous form because it readily leaks into the atmosphere and escapes into space. It is difficult to transport and store, requiring specialised million-dollar containers to maintain it in liquid form at temperatures below -269°C.[7] Helium-based cryogenic systems are the foundational infrastructure that enables the ultra-low temperatures required for the operation of quantum technologies. Two distinct helium-based systems are relevant: dilution refrigerators, which use a circulating mixture of two helium isotopes, helium-3 and helium-4, to reach sub-kelvin temperatures (below −272°C), and cryocoolers, which use helium-4 alone to reach the few-kelvin range (2–10K).

A dilution refrigerator is a helium-based cryogenic system that resembles a human-sized golden chandelier, with stacked gold-plated copper plates and intricate wiring used to cool hardware to almost the lowest attainable temperature in the universe. It is the standard system for reaching the base temperature required for quantum computing, since many qubits operate reliably only when thermal noise is nearly eliminated. This requires extremely precise engineering, because even a single misplaced wire can introduce enough heat to disrupt the system.[8] Each dilution fridge requires 10-100 litres of helium-3 gas, priced at US$ 2,500–3,000 per litre with lead times of 6 to 12 months. Helium-3 alone can constitute up to a quarter of the total acquisition cost of a dilution refrigerator, which can exceed US$ 600,000.[9]

Helium-4, while subject to the price volatility described above, is naturally occurring in recoverable quantities, whereas helium-3, about a million times rarer than helium-4 on Earth,[10] is produced almost exclusively as a decay product of tritium, a radioactive hydrogen isotope generated in nuclear weapons programmes and select nuclear energy reactors.[11] Helium-3 is extremely scarce, expensive, and tightly regulated. Helium-3 supply is dominated by the US, Russia and Canada, with production capped at 22,000–30,000 litres per year, a figure dwarfed by projected quantum-sector demand as the technology scales.[12] In India, helium-3 is extracted from heavy-water nuclear reactors, but no public data exists on extraction volumes or rates.[13]

Not all quantum architectures and technologies are equally exposed to Helium supply constraints. Photonic quantum computers and quantum communication devices (including single-photon detectors and quantum memory) operate at the less demanding few-Kelvin range using closed-cycle helium-4 cryo-coolers, making them less vulnerable to helium-3 scarcity, though not insulated from helium-4 price shocks. Quantum sensing applications, notably SQUID magnetometers and bolometers used in defence and medical contexts, span both temperature regimes depending on sensitivity requirements.[14] The most exposed architectures are also the most strategically significant: superconducting quantum computers—the modality pursued by leading tech companies such as IBM, Google, and most national quantum programmes—and semiconductor spin-qubit systems both require dilution refrigerators, making them dependent on both isotopes.

Without helium-3, many quantum machines cannot run, and most companies and countries lack secure, continuous access to it. Scaling quantum computers from current cryogenics to fault-tolerant quantum computers with millions of superconducting or semiconductor spin qubits will require dozens, or even hundreds, of interconnected dilution refrigerators.[15] NATO and the EU have flagged helium-3 as a high-priority supply chain risk in the context of quantum technology scaling.[16] To scale practical quantum system deployment with current cryogenics and avoid helium-3 becoming both a dominant per-qubit cost and a potential supply bottleneck, new helium-3 sources need to be secured.[17]

Lunar Gamble and Promise of Helium-3

Lunar samples collected from Apollo-era space missions identified the presence of deposited helium-3 on the moon’s surface. It is estimated that lunar helium-3 reserves, accumulated over billions of years of solar wind bombardment, amount to over a million metric tonnes.[18] Although lunar mining is still technologically nascent and untested, with its feasibility disputed, companies such as Maybell Quantum and Bluefors have already signed agreements to secure helium-3 extracted helium-3.[19] Bluefors, the world’s leading cryogenic manufacturer for quantum technologies, has signed an agreement with Interlune for a decade-long delivery scheduled from........
