Maybell
ColdCloud®

Patented cryogenic infrastructure built for energy-efficient, reliable scaled quantum applications

Designed without compromise, Maybell’s ColdCloud® delivers ultra-low temperatures with efficiency, reliability, and performance impossible to achieve without our patented technology. This is the infrastructure that qubit builders need to reach utility-scale and beyond.
The world's first utility-scale cryogenic architecture, ColdCloud® decouples 4 Kelvin pre-cooling from the millikelvin stages, serving independent nodes below 10 mK from a centralized plant. It is an order of magnitude more efficient and more powerful than any existing sub-Kelvin system, and is protected by an extensive U.S. patent portfolio no other organization can replicate.

Scalable

Operate your 4K stage at 8-15% of Carnot Efficiency, instead of the <1% typical in a pulse tube-based dilution refrigerator; reduced Helium 3 requirements by as much as 80%; spend up to 70% less installing and operating your lab.

Reliable

Scale cooling power without scaling failure points through centralized 4K and optimized mK systems; expected uptime: 96-99.9%

Fast

Nodes cool to base temperature in hours, not days. Facility-scale systems can be delivered in less than 24 months.

Flexible

ColdClouds can be optimized for base temperatures between <10mK and 6K+. System nodes can be warmed, cooled, and serviced independently, maximizing system availability.
