This confirms the finding from the previous research session (March 20, 2026). + +LEMON project context: +- Full name: Large-Scale Magnetic Cooling +- EU EIC Pathfinder Challenge: €3.97M, September 2024 – August 2027 +- Objective: develop a scalable, He-3-free, continuous cADR system for "full-stack quantum computers" (language from the project description implies targeting superconducting qubit temperatures) +- Partner: Kiutra (Munich, Germany) +- Status as of March 2026: sub-30 mK achieved continuously; working toward lower temperatures for qubit requirements (10-25 mK) + +February 2026 update (previously noted): Kiutra stated LEMON is making "measurable progress toward lower base temperatures." + +The LEMON project ends August 2027. If sub-10-15 mK is achievable within the project scope, commercial products at qubit temperatures could emerge by 2028-2030. + +Gap remaining: 27-30 mK achieved vs. 10-25 mK required for superconducting qubits. A 2x gap, vs. the 4-10x gap of commercial ADR. Narrowing but not closed. + +## Agent Notes +**Why this matters:** This is a status update / confirmation of prior session data. No new information beyond APS confirmation that the sub-30 mK milestone is real (not just a press release — it was presented at a major physics summit). The directional implication for He-3 demand remains unchanged: plausible 5-8 year commercial path to qubit-temperature He-3-free systems. + +**What surprised me:** The project explicitly targeting "full-stack quantum computers" — this suggests Kiutra/LEMON understand that their market is superconducting qubits, not just research cryostats. They're designing for the He-3 substitution opportunity from the start. + +**What I expected but didn't find:** Any specific target temperature for the LEMON project's end deliverable. The project description says "millikelvin" and "full-stack quantum computers" but doesn't specify a target in mK. This remains the key open question. + +**KB connections:** This is a minor update to the He-3 substitution risk thread established in sessions 2026-03-18 through 2026-03-20. Primary connection is to the claim candidates from those sessions. + +**Extraction hints:** No new claims this session — this is confirmation of existing finding. The extractor should update the prior session's archive notes if extracting from those sessions. + +**Context:** Kiutra is the leading He-3-free ADR company. Their LEMON project is the most advanced Western He-3 substitution program. The APS presentation suggests the research community is watching this as the primary He-3-free alternative path. + +## Curator Notes +PRIMARY CONNECTION: [Session 2026-03-20 He-3 ADR archives] +WHY ARCHIVED: Confirmation of prior session finding at a major academic venue — upgrades the credibility of the sub-30 mK milestone from "press release" to "peer-verified." +EXTRACTION HINT: This is a minor update — extractor should note APS confirmation but primary value is in the prior session's archives which have more complete context.
