Maybell Quantum Dilution Refrigerators Power the QUB on Open Quantum

Maybell's dilution refrigerators power the cryogenic infrastructure inside the Quantum Utility Block, with fridge telemetry surfaced remotely through Open Quantum.

About Maybell Quantum

Maybell Quantum is a quantum infrastructure company from Denver, Colorado. Every system it ships is designed and manufactured in the United States. Maybell is dedicated to making dilution refrigerator infrastructure reliable and accessible, removing cryogenics as the bottleneck to scaling quantum computing.

The Maybell product family covers a range of use cases. The Fridge offers a compact footprint with 360-degree access. The Fast Fridge is designed for affordability and rapid iteration. The Fridge+ delivers roughly four times the sample capacity and faster swap times. The Big Fridge scales to approximately two times the power and five times the sample capacity for production-scale deployments. All Maybell systems consistently achieve base temperatures below 10 mK, the threshold that superconducting quantum processors require.

Dilution Refrigerators

Four-model product family — Fast Fridge, Fridge, Fridge+, and Big Fridge — engineered for quantum labs from early-stage research through production-scale deployment, all achieving below 10 mK base temperature.

ColdCloud Platform

Maybell's patented architecture for scalable quantum cryogenics, delivering datacenter-ready reliability with up to 10x efficiency improvement and cooldown times measured in hours, not days.

Monitor Your Fridge from Anywhere

Maybell systems monitor the cryostat continuously and expose live temperature and system-health telemetry locally at the fridge. ColdCloud, Maybell's patented cryogenics architecture, handles the cooling itself, compressing cooldown times from days to hours.

Open Quantum pulls that fridge-local telemetry for unified remote operations. Operators running an on-premises Maybell system as part of a Quantum Utility Block (QUB) or Q-PAC deployment can monitor their fridge from anywhere. Check cryostat health and temperatures from the same place you submit circuits and manage your QPU, without needing to switch between systems. Read more about the operator experience on the For Labs & QPU Operators page.

Maybell in the Quantum Utility Block and Q-PAC

The Quantum Utility Block (QUB) is a pre-validated, on-premises quantum computer jointly engineered by QuantWare , Qblox , and Q-CTRL . The stack consists of three interoperable layers: a QuantWare superconducting QPU, Qblox control electronics, and Q-CTRL's Boulder Opal autonomous software.

Elevate Quantum’s Q-PAC is the nation's first quantum open-architecture system and a flagship deployment of the QUB reference architecture. Maybell supplies the custom cryogenic wiring interconnect and dilution refrigeration unit for Q-PAC.

Superconducting qubits operate at temperatures near absolute zero, roughly 10 to 20 millikelvin, where thermal noise cannot destroy the quantum states they encode. Reaching and holding those temperatures requires a dilution refrigerator, and operating one reliably at scale requires infrastructure purpose-built for quantum computing. Maybell builds the cryogenic systems keeping the QUB cold and functional.

Why It Matters on Open Quantum

Remote Fridge Monitoring

Open Quantum pulls telemetry from your Maybell fridge so you can check cryostat health and temperatures from anywhere, without a separate tool or an on-site visit.

Unified Remote Operations

Run circuits and watch your fridge from the same dashboard. For labs putting on-premises systems on the cloud, this is what unified QPU operations looks like.

Datacenter-Ready Reliability

ColdCloud's patented platform claims up to 10x efficiency improvement and cooldown in hours, keeping Maybell systems online and maximizing available compute time.

Complete QUB Stack

Maybell cryogenics integrate with QuantWare QPUs, Qblox electronics, and Q-CTRL software inside the QUB reference architecture that Open Quantum brings to the cloud.
