[Tom's Hardware] Permanent Magnetic Cooling System for Quantum Computers

"All we need is electricity"

https://www.tomshardware.com/news/pe...tum,39586.html

I thought this was a very interesting discovery with much broader implications. No information on how it works but from what I can tell, it just uses electricity (and maybe magnets?).

While they are starting a company to provide this technology for quantum computing, I'm curious if they have plans to downscale the technology into a package able to be used for mainstream computer cooling requirements.

I'm quite certain they don't.

The needs of quantum computing are not even remotely the same as for traditional electronics. For starters, quantum computing requires cooling to temperatures that would cause conventional electronics to simply stop functioning. What's more important is that you're trying to cool individual atoms and not macroscopic objects with power output in the hundreds of watts. The entire technical approach simply won't apply to macroscopic objects.

Other ways of cooling atoms involve pinning them with interfering laser beams, so that the atoms get stuck in the nulls of the electromagnetic standing wave. How can you apply that to a macroscopic object? You can't. At all. Quantum objects simply don't behave the same way.

You want an "electricity only" way of directly cooling a traditional CPU, you can buy a TEC. You still have to worry about heatsinking, however, which gets you back to where we are now with heatpipes and blowers or liquid transfer.

Macroscopic cooling =/= microscopic cooling.

Well it should be an upscale of some magnitudes not a downscale lol

If you want to use electricity to "cool something" use peltier cells, they were quite common in early 2000s for overclockers if I recall well....
