I am just now realizing: Baroque In Mind… Broken mind? Maybe they’re a troll.

Yeah, totes. Scentless non-toxic gases can still be deadly by merit of not being oxygen.

The only recreational octave-shifting gas I indulge in is Sulfur Hexafluoride. Bolsters the ol’ baritone.

I’m prepared to be proven wrong on this, as my exposure to quantum computer cooling systems has been super brief, but as far as I know there are no toxic coolants.

The pre cooler is a Pulse Tube Refrigerator, and the main cooler is a Dilution Refrigerator. Those both use helium, and that stuff floats out into space. I doubt it’s going into the ocean. Here’s another article that talks about the operation.

Like I said though, my exposure was brief. Unfortunately we didn’t land any projects with the supercomputer people 😞. I’m always down to learn more about niche topics though. Makes me super fun at parties. If you have good sources shoot them my way. I couldn’t find anything in my 5 ish minutes of web searching.

This is the right answer. It’s a big cryogenic refrigerator called a Dilution Refrigerator. It’s fancy stuff. Needs Helium-4, which is more common, and Helium-3, which mostly comes from nuclear production.
