“Teleporting quantum information is now a practical reality,” asserts Deutsche Telekom. The firm’s T‑Labs used commercially available Qunnect hardware to demo quantum teleportation over 30km of live, commercial Berlin fiber, running alongside classical internet traffic. In an email to Tom’s Hardware, Deutsche Telekom’s PR folks said that Cisco also ran the same hardware and demo process to connect data centers in NYC.

Quantum is a struggle for me to understand because, I feel like the current explanations don’t suffice why you can’t transmit information. To me, this still sounds perfectly viable for information transfer… just don’t encode information via polarization. You would encode it as a primitive derived from whether or not state collapse has happened yet or not.

Using the same/similar mechanism they can use to determine collapse happens to both entangled particles at the same time (faster than light), can they not also determine whether or not collapse has happened at all?

Maybe it’s that checking for collapse will actually cause collapse, thus ruining the information channel. But, perhaps then, you just add more entangled particles. Have some mechanism established with “throwaway” particles that can have their state collapsed either as a chain reaction or via the polling process.

Obviously I’m not the smarted person here… probably a lot wrong with my above assumption. But my point is really that explanations about quantum seem to be unsupportive to the claims they make about quantum.

AFAIU you can't determine whether the state on the other side has been collapsed. All you can say with certainty is the state on the other side after you have collapsed yours.

I'd recommend this excellent series if you want a good grounding:

And I also found this video which I haven't watched but I expect will be good and probably attacks your pondering more directly:
