Maybell Quantum, a Denver-based startup that plans to build hardware for the budding quantum computing ecosystem, is coming out of stealth today and launching Icebox. As the name implies, Icebox is a cryogenic platform to cool quantum processors down to the very low temperatures it takes to run a stable quantum system. Traditionally, these are extremely large systems but Maybell says its Icebox is able to support three times as many qubits in one-tenth the space of currently used setups.

“You always see this image of the beautiful golden chandelier. It’s a starkly stunning image, but what you don’t see is what’s associated with that golden chandelier: between two and hundred square feet of tubes and wires and pumps and compressors and liquid nitrogen dewars and noncontact cooling water and all these other things that you need in order to get the bottom of that golden chandelier down to millikelvin temperatures,” Maybell founder and CEO Corban Tillemann-Dick told me.
