Radio physics is often presented as if there are infinitely many channels available, one for each wavelength. In reality there’s only one channel, and receiving a transmitted signal relies on the time integral of its carrier frequency with all other signals being negligible.

While the quantum analysis of this question is very rich and beyond my skill level, the general result is that it doesn’t reveal a vastly more bandwidth rich version of electromagnetic theory, because the uncertainty principle claws back the apparent gains.

interesting point of view, thanks it is intriguing that the uncertainty principle applies in the analog electromagnetic theory and in quantum mechanics; in quite different ways, but maybe also in some deep sense, the same

In physics, a quantum (plural quanta) is the minimum amount of any physical entity (physical property) involved in an interaction.. A photon is a single quantum of light (or of any other form of electromagnetic radiation) Is a single quantum the minimum mass of EM radiation?

seems like photons coming in actual separate quanta of energy actually invalidate this…?
but i like the idea of this in the analog processing perspective, and it may be the most useful engineering perspective
