Thermal insulation in quantum computers

Click For Summary
SUMMARY

This discussion focuses on the thermal insulation techniques utilized in D-Wave quantum computers to achieve extreme low temperatures. The cooling system comprises multiple stages that progressively lower the temperature, but concerns arise regarding thermal propagation through the metal structure connecting these stages. Effective thermal insulation is critical to prevent heat transfer from the computing core to the cooling stages, ensuring optimal performance of the quantum system.

Hello!
I was watching a video () about how extreme low temperatures are achieved in a D-Wave computer. As they explain, they have this series of cooling stages, each of which providing a temperature drop over the previous. I was wondering however, how could they avoid thermal propagation through the metal structure that holds the whole thing together? I mean those rods that physically connect all the stages and ultimately the computing core.
Thanks for you patient replies! :)

Considering that the structure connects to the core, the it may also affect the metal structure so that it does not affect the stages. (The core may cool down the structure). Just guessing.
 
woops! :headbang:
