Enabling technologies / enablers/dilution-refrigeration

Dilution refrigeration

proposednot assessed

Cryostats that cool devices to a few millikelvin and remove the heat that wiring, amplifiers and control electronics add at that temperature.

Scope

In scope: dilution refrigerators and their cooling power at the stages where qubits and cold electronics sit. Out of scope: the control electronics themselves (enablers/cryogenic-control-electronics) and cooling at room temperature (enablers/heat-removal).

Metrics

Cooling power headline

Heat a refrigerator can remove at the stated temperature. Higher is better.
Cooling power: log scale, one tick per order of magnitude; better to the rightnow

Conditions. Cryogen-free dilution refrigerator with four parallel dilution units, at 102.48 mK; the power at the 10-20 mK qubit stage is far lower.

Dependencies

Requires

Nothing recorded.

Required by

  • Fault-tolerant quantum computer Superconducting qubits operate at about 10 mK, and every control line and amplifier adds heat to that stage. Need: Enough cooling power, in one cryostat or several linked, for the heat load of up to a million physical qubits and their wiring.
