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
