TLDR
In this article, it was shown that phonons can be coherently transferred between two nanomechanical resonators, and the technique of controlling the coupling between nanoscale oscillators using a piezoelectric transducer is useful for manipulating classical oscillations, but if extended to the quantum regime it could also enable entanglement of macroscopic mechanical objects.Abstract:
It is now shown that phonons can be coherently transferred between two nanomechanical resonators, it is now shown. The technique of controlling the coupling between nanoscale oscillators using a piezoelectric transducer is useful for manipulating classical oscillations, but if extended to the quantum regime it could also enable entanglement of macroscopic mechanical objects.read more

Nonlocal heat transfer between resonators by Cooper-pair splitting
TL;DR: In this article, a Cooper-pair splitter setup consisting of two quantum dots, each linearly coupled to a local resonator, is investigated, and it is shown that cross-Andreev reflection through which Cooper pairs are split into both dots, can efficiently cool down simultaneously both resonators into their ground state, and a nonlocal heat transfer between the two resonators is activated when opportune resonance conditions are matched.
