> the problem is that you can put something into a wormhole, but to get it out the other end, you have to carry the encoding you get to the other end of the wormhole to decode the output.

That sounds a lot like how entangled particles can't be used to communicate faster than light.

While you can make observations immediately, you can't turn them into useful information about the other end, at least not until you get missing data which has to reach you by normal means.

Hence the focus on using entangled particles as a kind of tamper-detector or "reusable random one-time pad", rather than for transmitting information.

That is precisely the lesson of the ER=EPR principle, which states that every entangled pair really has a 1-qubit wormhole connecting it, and the space inside a macro-scale wormhole is the consequence of combining all those tiny wormholes together. Wormholes are entanglement.
