Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually [2]uses noise to drive cooling instead of fighting it . By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.

Sounds like basically, they built [1]Maxwell's demon [wikipedia.org] as a machine.

Excellent! Now bring on the tiny quantum beers!
