This is a dilution refrigerator which is capable of cooling things ... The critical step at this point is to evacuate the refrigerant lines so they can be filled with expensive Helium-3 and Helium-4.

Kislat says the dilution refrigerator uses pretty much the same process our kitchen refrigerators use. It’s based on an idea called phase transition. He says you can think of it like lemonade.

To cool quantum computing components, researchers use machines called dilution refrigerators. Researchers and engineers from the SQMS Center are building Colossus, the largest, most powerful ...

Fabian Kislat's dilution refrigerator at the University of New Hampshire. (Mara Hoplamazian/NHPR) It’s a warm July day when I meet Fabian Kislat in his lab.

Helium dilution refrigerators are an irreplaceable element for the research and development of quantum computing, providing an extreme cryogenic environment for quantum computers to function ...

However, temperatures below about 300 mK cannot be reached by simply cooling with liquid helium. Conventional cooling to millikelvin temperatures is done using a dilution refrigerator, which involves ...

No liquid helium dilution refrigerators are able to achieve an extreme temperature of just 0.01 degree above the absolute zero without the aid of liquid helium, ...
