That's pretty standard for experimental quantum systems. A lot run on helium fridges at 4K. The superconducting stuff even colder, in 10 mK dilution fridges.

Anyone better at physics than me willing to explain how this does not break general relativity ?
I might be missing the point of the experiment completely to be fair

Sorry?
(I have a feeling someone meant Kelvin, though 267 K is hardly ‘extremely cold’ either…)
