Cold rush: As quantum computers get bigger, researchers scramble to chill hardware without rare helium-3

Chasing absolute zero
Dilution refrigerators are roughly human-size plumbing systems that use rare helium-3 (He-3) to chill tiers of copper plates to millikelvins (mK), near absolute zero. These temperatures are required for sensitive technologies, such as the chips that power quantum computers.
