> The usual solution to a weak radio signal is to find a bigger signal, for instance, by picking a different radio station or by moving to the other side of the room.
The former solution is as sustainable as repairing your car by taking the bus.

This reads like technology for a noiseless receiver. It is not a usable radio yet ("this circuit could enable sensing of radio frequency radiation with quantum resolution" [0]).

It's actually not technology for a noiseless receiver. It's technology for detecting megahertz photons at quantum resolution. You'll still have noise!
Bloody clever experiment; thanks very much for the link! When I get all grouchy for how terrible current year is, that paper saves 2019 for me.
