I'd like to be the first to complain that resonant power transfer has nothing to do with quantum entanglement.
Entanglement, no. Tunneling, yes... if you like to market your device by insisting on quantum descriptions of things that involve transition rates
of 10^28 photons per second. A ~10MHz photon doesn't pack a very big punch, energy-wise.
It's a classical effect but can be framed in quantum terms for "welcome to the future" cred.
It's called Shannon's Law -- and no matter how you sex up the technology, the fact is you're raising the noise floor doing this.
Bad engineer. No cookie for you.
Except that energy transfer is not information transfer, and doesn't really require any bandwidth. Of course, every emission has *some* bandwidth due to noise, etc, but you should be able to do wireless power with very narrow band oscillators and I suspect you have confine emissions to the the ISM (industrial, scientific, and medical) bands. Maybe it needs a little bit of slow digital transmission if you need to sync devices and chargers beyond just whether or not there is another resonant device around (you don't want charging stations trying to feed power to each other).
But the fact of the matter is that resonant power transfer requires sharply resonant circuits, so you can't emit much power over a wide bandwidth even if something goes wrong.
