Quantum Computers: Cracking The Cooling Code

Quantum Computers: Cracking The Cooling Code

Researchers from the physics department at the Technical University of Munich (TUM) may have cracked the cooling code, however, to reach a near absolute zero temperature on a permanent basis.

Developed as part of a startup called “kiutra GmbH,” the team says it succeeded in implementing a permanent magnetic cooling system for quantum computers. The team of scientist came up with the idea during their work at the TUM. Again and again, they were faced with the limits of conventional methods for reaching such low temperatures. The group, therefore, developed its own technology to ensure permanent cooling and founded kiutra GmbH in the summer of 2018.

Liquefied gases are typically used to reach ultra-low temperatures. To get close to absolute zero (-273C), researchers in the past have used helium-3, a rare and expensive isotope. Magnetic cooling offers an alternative by generating low temps using inexpensive solids, but are not feasible for long-term use—they’re only good for a limited period of time.
