2nd law of thermodynamics a slight twist on what we know

[Starstruck69]

I was reading an article (link below) on Reversing the thermodynamic arrow of time using quantum correlations.

Bottom line of the paper from my understanding is the 2nd law of thermodynamics is reversed under certain conditions. It isn't a violation of the 2nd law as the particles have to be correlated and in the presence of a magnetic field. (2nd law does not cover this.)

What do you guys think to the significance of the work and what  future questions would like answering?

I know this isn't spaceflight per say but very significant in this area of physics which of course makes spaceflight/travel possible for us mere humans(and kerbals:))
