Well, this is an unexpected advance:
It's basically a universal radio, picking up all frequencies at once, up through the more useful microwave bands (though this prototype doesn't quite get to the highest 5G band).
Even though it's based on quantum effects, it's likely going to be able to be miniaturized as it doesn't require extreme cold or anything exotic.
@SwindlerOfInsanity I'm pretty sure it doesn't.
Are you envisioning sending across all the spectrum at the same time?
