Description of need
Quantum computers needs to run at ~10 mK, and can’t tolerate large magnetic fields (like the ones required for competing technologies like nuclear demagnetization refrigeration or adiabatic magnetization refrigeration)
Problem severity (1-10)
Who has this need
Total addressable market (TAM)
Solutions today, and their shortcomings
Dilution refrigeration is one of the only technologies available for cooling in the mK range. It relies on a mixture of helium-3 and helium-4. There are several drawbacks: - Helium-3 is actually becoming a scarce material. - Large energy consumption - Large spatial footprint for equipment
