The
Big
Fridge

Scale up your quantum research

The Big Fridge offers twice the power and four times the capacity for labs that demand scale.

Twice the power

Take advantage of unprecedented cooling capability for the most demanding quantum applications.

1000 µW cooling power @100 mK handles massive wiring trees and active components
Powerful pre-cooling system maintains base temperature even with high heat loads
Multiple temperature-controlled experimental zones can be configured for independent operation

Four times the volume

Enjoy massive experimental space that opens new possibilities for quantum research and development.

>1,700 cm² wiring area on each temperature stage for unprecedented connection density
130 L+ sample volume accommodates the extremely large quantum processors or sensor arrays
Modular wiring inserts compatible with Fridge+ and Fast Fridge
Compatible with running many parallelized experiments or characterizing the most samples in any commercial system

Unlimited potential

The Big Fridge is designed as the foundation for the quantum data centers of tomorrow.

Scalable architecture supports linking multiple Big Fridges into quantum computing clusters
Designed for 24/7/365 operation with redundant systems and hot-swappable components
Standard interfaces for integration with quantum control stacks and classical computing resources
Backward-compatible thermal plate spacing for easy migration from competitor systems
Future-proof infrastructure with upgrade paths for emerging quantum technologies

Obsessively designed & tested

Unmatched reliability

No scroll pumps, no solder joints or acid flux, no indium or epoxy, 90% reduction in rubber gaskets (compared with leading competitor), and self-regenerating helium traps

User-centric design

Front-opening access, integrated workspace, and intuitive controls that let you focus on your research, not your fridge

Superior performance

Consistently performs better than specifications with base temperatures below 10mK and the quietest experimental environment in the industry

Expert support

Three-year comprehensive and ten-year dilution unit warranty with same-day response and a dedicated global team to help you succeed

American made

Designed and manufactured in Denver, Colorado with rigorous quality control and testing
