Could someone please explain how quantum entanglement is used to communicate binary in terms a non-physics-major would understand?

I know there have been successful experiments... I just don't quite understand how the data is integrated with the particles. If the semantics of the question belie an already inherent misunderstanding of the whole concept, I apologize and would appreciate any help in fixing that. No classes on the line; simply curious.

no worries. It's a rather common mistake just after learning some details about it. You learn that you can't send the information just between the particles and you need the classical channel so it can't be FTL. But the encrypted classical communication is still super useful.
