Large scale entanglement experiment

[T C]

TL;DR

Given below is the research paper and a related video to understand the phenomenon. This experiment is a proof of large scale quantum entanglement can be possible now.

This is the paper and here is the video. As far as I know, this is an entanglement related experiment done so far in such a large scale. I want to know whether entanglement related experiment has been done so far on a larger scale and what can be the possible use of such phenomenons.

Entanglement experiments with Josephson junctions have been done for some time now; those are larger, IIRC, than the drumheads in this experiment.

The interesting part of this experiment is that the degrees of freedom being entangled are mechanical.

We also have this experiment conducted in 2011:

I am now interested in practical applications about such phenomenon.
