I’ve read some weird paper about such an analog channel, where something quantum on both sides was used to create another analog signal used kinda as an encryption key. Stumbled upon it trying to understand some things about optics long ago.
Because you can use one time pad encryption which is theoretically unbreakable. Intercepting the photons used to generate these keys would instantly alter their state thus making them unusable.
This is not a “quantum entangled data link”, it is a regular radio data link secured using quantum computing to generate encryption keys.

oh right one time pad.
It really does feel like you could do this in a better way, though.
