About Maybell Quantum
Colorado maker of dilution refrigerators and cryogenic RF systems for quantum computers, including the Big Fridge developed with Colorado School of Mines. It raised a $25 million Series A in March 2024 and a $40 million Series B led by Addition in September 2025, and is to deploy four refrigerators at the Roadrunner Quantum Lab in Albuquerque by September 2026.
Maybell Quantum was founded in 2021 and is based in Denver, CO, United States. It is listed under Quantum Computing, Superconducting Computing. Reported funding is $40M Series B, Sep 2025.

What Maybell Quantum works on
Quantum Computing
A quantum computer is a machine that uses the rules of quantum physics to process information. Its basic unit is the qubit. A classical bit is either 0 or 1. A qubit can be in a superposition, a state that combines both, and its measured result is probabilistic.
Superconducting Computing
Superconducting computing uses circuits made of materials that have no electrical resistance when cooled below a critical temperature. The common material is niobium, which works at about 4 kelvin (around minus 269 degrees Celsius), the temperature of liquid helium. Without resistance, the wires do not waste energy as heat.
