Sub-Kelvin Coolers

Specialized cooling systems designed to achieve temperatures below 1 kelvin, often through dilution refrigeration, adiabatic demagnetization, Joule-Thomson expansion or evaporative cooling. These systems can offer continuous cooling of samples to sub-Kelvin base temperatures or operate on a cold/warm duty cycle. They are essential for quantum computing applications where superconducting qubits require ultralow temperatures for stable and coherent operation, and for quantum networking applications where superconducting single-photon detectors and elements of quantum repeaters benefit from sub-Kelvin temperature operation.
