Maybell Quantum

Maybell Quantum, founded in 2021, designs and manufactures American-made dilution refrigerators to provide the cryogenic infrastructure required for quantum technologies. Based in Denver, Colorado, with a European headquarters in Copenhagen and a new facility in New Mexico, the company serves research institutions, national laboratories, and quantum computing firms in more than 12 countries.

The company's product line, which includes the Fast Fridge, Fridge, Fridge+, and Big Fridge, consists of engineered dilution refrigerators that achieve base temperatures below 10mK. These systems are designed to support more qubits within a smaller physical footprint. In 2026, Maybell Quantum launched ColdCloud, a patented modular cryogenic cooling architecture that delivers up to a 10x efficiency improvement and is designed for datacenter-ready reliability.
