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

Strong indirect coupling between graphene-based mechanical resonators via a phonon cavity
Gang Luo,Zhuo-Zhi Zhang,Guang-Wei Deng,Hai-Ou Li,Gang Cao,Ming Xiao,Guang-Can Guo,Lin Tian,Guo-Ping Guo +8 more
TL;DR: In this article, the experimental observation of strong indirect coupling between separated mechanical resonators in a graphene-based electromechanical system is reported. But the results may lead to the development of gate-controlled all-mechanical devices and open up the possibility of long-distance quantum mechanical experiments.

Ultra-Sensitive Force Transduction in Weakly Coupled Resonators
Hemin Zhang,Milind Pandit,Jiangkun Sun,Dongyang Chen,Guillermo Sobreviela,Chun Zhao,Ashwin A. Seshia +6 more
TL;DR: In this article, a transducer configuration employing weakly coupled resonators demonstrating significant modal overlap is reported. But, the sensitivity of such systems significantly increases as the coupling strength between resonators is reduced, moving the system to a regime described by modality overlap.
