## Content

Munich-based kiutra raised €13M ($15.2M) in October 2025 to commercialize He-3-free magnetic cryogenic cooling for quantum computers. Round led by NovaCapital (Italy) and 55 North (Denmark), with HTGF (Germany), total funding over €30M.

Key facts:
- Technology: Adiabatic Demagnetization Refrigeration (ADR) using paramagnetic solids — no He-3
- Current status: **Already deployed worldwide** at research institutions, quantum startups, and corporates
- Stage: Transitioning from R&D startup to industrial scale-up
- Expanding into modular platforms for complex quantum chips and full-stack quantum computers
- NATO and EU have flagged He-3 supply as a quantum technology supply chain risk
- Kiutra positioned as strategic response to European/NATO He-3 supply vulnerability

Context: He-3 is produced primarily from tritium decay in US and Russian nuclear stockpiles. These are aging and declining. He-3 supply has already constrained experimental physics for 15+ years. NATO and EU initiatives have flagged He-3 as a critical technology supply chain risk — kiutra is directly responding to this institutional demand.

## Agent Notes

**Why this matters:** This is the most important data point for the Pattern 4 disconfirmation: kiutra's He-3-free ADR systems are **already commercially deployed**. The "no terrestrial alternative at scale" premise of Pattern 4 is already false in the research institution market. The question is whether ADR scales to full-stack quantum computers at data-center scale.

**What surprised me:** The NATO/EU supply chain risk flagging — this is the European parallel to DARPA's US urgency. Multiple governments independently recognizing He-3 as a supply chain vulnerability increases the pressure for institutional adoption of alternatives, systematically reducing the addressable market for Interlune.

**What I expected but didn't find:** Temperature floor specs for kiutra systems — what's the base temperature reached by their ADR without He-3? If they reach 10-25mK, they're a direct substitute. If they reach 100-500mK, they're partial substitutes requiring He-3 pre-cooling.

**KB connections:**
- Pattern 4: counter-evidence that no terrestrial alternative exists at scale — kiutra IS deployed at scale in research contexts
- [[space governance gaps are widening...]] — parallel: technology advances (He-3-free ADR) advancing while institutions (He-3 supply chain planning) are still assuming He-3 dependence

**Extraction hints:** Extract claim: "He-3-free ADR cryogenics are already commercially deployed at research institutions, undermining the premise that no terrestrial alternative to He-3 quantum cooling exists." Confidence: likely — but note the research institution vs. full-stack quantum computer deployment distinction.

**Context:** kiutra's research institution deployment means the alternative already exists in the R&D sector. Full-stack quantum computers (the scale-up market Interlune is targeting) may take another 3-7 years to adopt He-3-free systems at data-center scale. The question is timing relative to Interlune's 2029 delivery.

## Curator Notes

PRIMARY CONNECTION: Pattern 4 He-3 demand robustness — most direct evidence that the "no terrestrial alternative" assumption is already false.

WHY ARCHIVED: Commercial deployment at research institutions is the key fact — this moves ADR from speculative to proven-in-limited-context. The remaining question is scale-up to data-center quantum computing.

EXTRACTION HINT: Extract as "experimental" confidence claim — ADR is proven at research scale, not yet at commercial quantum computing scale. The extractor should acknowledge kiutra's deployment while noting the scale gap to Interlune's target market.
