Thermal insulation in quantum computers

AI Thread Summary
Extreme low temperatures in D-Wave quantum computers are achieved through a series of cooling stages that progressively lower the temperature. A key concern is how to prevent thermal propagation through the metal structure connecting these stages to the computing core. The physical rods may conduct heat, potentially impacting the cooling efficiency of the system. It is suggested that the core's cooling could influence the metal structure, raising questions about thermal management. Effective thermal insulation strategies are crucial for maintaining the necessary low temperatures in quantum computing environments.

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:
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
