The only time any information can be encoded onto entangled particles is when they’re created.
If that were the case, then we aren’t really doing FTL communication, unless we manage to entangle them at a distance. No?
OIC, it’s still useful if we want to make a secret key and send it somewhere. Then both sides can take a reading sometime in the future and they can then use whatever cluster of entangled particles they saw, as the symmetric key.
