Fast-Cycle Dilution Refrigerator

Lawrence Berkeley National Laboratory is conducting market research to identify sources that possess the capabilities and experience necessary to provide a fast-cycle dilution refrigeration system.

With ever-increasing numbers of quantum bits (‘qubits’) on a superconducting quantum computer chip, defects in the design and materials will be amplified and result in unusable qubit lifetime during scale-up. The optimization of design and materials as well as exploration of potential new materials for the system rely on sequential experiments, where parameters of a previous step are necessary for the optimization of the next. Such iterations are typically hindered by the long cycling time of a dilution refrigerator. A fast-cycling dilution refrigerator is essential equipment for circuit design and material optimization for presevering performance such as qubit lifetime during scaling.
