This seems really cool, but I'm too dumb to understand it. Can any of our resident physics or chem people put it into something more venacular? I get that they used a system to virtually cool something, and that virtually cooling something makes it behave as it would at lower temperatures. I just can't understand how they did it

The only quantum things I understand is Quantum Leap.

This is not the R&P&S board.

Quantum mechanics is the DEVIL!

Ah, a true nerd. I would love to see a reboot of the show.

Yes, yes it is.

Well it is to those of us who can not really understand it beyond a basic level.

Quantum mechanical virtual cooling to me is just like a story I know called "the puppy who lost his way."

Same here. I'm nowhere near mathematically advanced enough to follow the equations, but usually I can at least get some conceptual grasp. Even if it is counterintuitive. But this article doesn't make sense at all to me. I can usually make heads or tails of things that end up in my science news feeds, but this one just makes me feel dumb. Several hours of research latter learning about quantum temperature, thermalization, and Bose Hubbard optical lattices, and I still feel just as stupid reading the article.

The best I can figure is they take a couple of separate identical but static semi-quantum systems, allowed tunnelling, then separated and made them static again and went looking for areas of lower temperature that resulted from the random hopping around of atoms.

Oooh me too

I'm watching Star Trek Enterprise right now and I think Scott Bakula just seems genuinely likeable

I would propose you ask this question on Forum 16. The general populace is certainly better educated than the pseudo-scientists that paste wiki links here.
