> extremely cold temperatures (267 °C)

Sorry?

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

Maybe a negative sign got dropped?

Seems like you're right! [1]

negative 267 C would be 6 Kelvin ???

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.
