Move Over Helium-3… Using Magnetism to Cool Quantum Computers

Cooling for quantum electronics

The start-up kiutra is the first company in the world to have succeeded in developing a permanent magnetic cooling system to reach temperatures close to absolute zero. Such temperatures are, for example, required for the operation of quantum computers. The system was set up by a team of researchers from the Physics Department at the Technical University of Munich (TUM)…

…Concepts for permanent magnetic cooling have been around for many years. “However, technical implementation is extremely challenging and this has previously prevented the development of a product for widespread use,” explains Tomek Schulz.

“We are the world’s first commercial supplier of a cooling system that can magnetically achieve temperatures close to absolute zero (near -273°C) on a permanent basis,” says Alexander Regnat. “Our great advantage is that we do not need expensive helium-3. All we need is electricity.” …READ MORE
