World's smallest radio receiver has building blocks the size of two atoms | Harvard John A. Paulson School of Engineering and Applied Sciences

The radio uses tiny imperfections in diamonds called nitrogen-vacancy (NV) centers. To make NV centers, researchers replace one carbon atom in a tiny diamond crystal with a nitrogen atom and remove a neighboring atom — creating a system that is essentially a nitrogen atom with a hole next to it. NV centers can be used to emit single photons or detect very weak magnetic fields. They have photoluminescent properties, meaning they can convert information into light, making them powerful and promising systems for quantum computing, phontonics and sensing.

Can't quite get the essence of this. They act like scintillators?
Seems like an opto-electrical link more than a radio from what I get from the video. No, take that back. A green laser is used to power the little nano receivers, a bit like Vcc to a transistor? The little atom pairs are more analogous to diodes or crystal diodes?
