## Content

Maybell Quantum (Boulder, CO) launched ColdCloud on March 13, 2026 — a distributed cryogenic architecture for scalable quantum computing. Key specs:

- **90% less electricity** per qubit than equivalent array of legacy dilution refrigerators
- **90% less cooling water** per qubit
- **Up to 80% less He-3 per qubit** vs. legacy dilution refrigerators
- Cooldown times in hours instead of days
- More than 10x energy efficiency vs. legacy systems
- First system going online late 2026; broader deployments 2027

Technical mechanism: ColdCloud separates the pre-cooling stage (centralized at facility scale) from the sub-Kelvin stage (distributed to modular nodes). The "Maybell-cycle" achieves liquefaction-class thermodynamic efficiency at the 4-Kelvin stage — roughly 16x improvement. This is architectural innovation, not materials science.

Maybell retains its He-3 supply agreement with Interlune (thousands of liters, 2029-2035). They did not cancel the agreement when launching ColdCloud.

## Agent Notes

**Why this matters:** Maybell is an Interlune customer. ColdCloud dramatically reduces per-qubit He-3 demand while maintaining volume commitments. This is the clearest evidence that the He-3 demand curve is decoupled from qubit count growth — net demand grows much slower than naive market projections suggest.

**What surprised me:** Maybell simultaneously holds a He-3 supply contract AND launches a product that reduces He-3 consumption per qubit by 80%. This is not contradictory — they're scaling qubit count while improving efficiency — but it means the demand forecasting for Interlune needs to account for efficiency improvements, not just scaling.

**What I expected but didn't find:** I expected Maybell's He-3 reduction to mean they were distancing from Interlune. Instead, both agreements remain active. The demand curve is real but growing more slowly than extrapolation from raw qubit deployment suggests.

**KB connections:**
- [[Varda Space Industries validates commercial space manufacturing...]] — parallel story: manufacturing demand is real but quantity may be smaller than hoped
- Pattern 4 (He-3 as first cislunar resource product): directly evidences demand uncertainty at scale

**Extraction hints:** Extract claim about demand decoupling between qubit count and He-3 consumption. The 80% reduction figure and the maintained supply contract together tell the full story.

**Context:** Maybell was founded to build quantum computing infrastructure. Their He-3 supply agreement with Interlune was announced in May 2025. ColdCloud is their infrastructure product aimed at moving quantum computing from R&D to datacenter deployment.

## Curator Notes

PRIMARY CONNECTION: [[the space manufacturing killer app sequence is pharmaceuticals now ZBLAN fiber in 3-5 years and bioprinted organs in 15-25 years...]] — He-3 is the lunar resource analog: real demand, but demand forecasting is more complex than headline contract numbers suggest.

WHY ARCHIVED: Direct evidence that He-3 demand per qubit is falling while volume commitments are maintained — this is the core tension in the Pattern 4 demand case.

EXTRACTION HINT: Focus on the combination: Maybell holds Interlune contract + launches 80% efficiency improvement. Extract claim that He-3 demand growth is decoupled from qubit count scaling. Note the architectural innovation (distributed centralized cooling) as the mechanism — not materials substitution.
