It’s not much to look at. Its case—the size of a pack of chewing gum–is connected to wires that transmit signals to a nearby panel of custom radiofrequency receivers. But most important, it’s nestled within a shiny gold cocoon called a dilution refrigerator and shielded from stray electrical signals. When the refrigerator is running, it is among the coldest places on Earth, so very close to absolute zero, less than 6 millikelvin (about −460 degrees F).
This is the right answer. It’s a big cryogenic refrigerator called a Dilution Refrigerator. It’s fancy stuff. Needs Helium-4, which is more common, and Helium-3, which mostly comes from nuclear production.
the methods required to maintain qubits are exotic.
this site mentions the refrigeration equipment youre referencing i believe https://www.pnnl.gov/news-media/new-superconducting-qubit-testbed-benefits-quantum-information-science-development

how in the absurd fuck do they get something that cold
With a refrigerator.
That’s a very big refrigerator
