I think it's less about sensing using the high Q, and more about exploiting the quantum properties of a mechanical widget (e.g., <a href="https://arxiv.org/abs/1210.3619" rel="nofollow">https://arxiv.org/abs/1210.3619</a>). The membranes in this paper each contain on the order of 10^14 atoms, and the idea that this could be manipulated coherently as a quantum object is pretty neat and potentially useful.Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-5479089203131321022021-03-31T01:28:01.324-05:002021-03-31T01:28:01.324-05:00Want to know something just as amazing?

Talk about reproducible!<br /><br />On the other hand, do you have anything to read for why a mechanical sensor with high Q would be so useful, as compared to an optical one?Anonymousnoreply@blogger.com
