> However, the state of the entangled systems is prepared before the systems are separated from one another
Isn’t the state still a probabilistic one at that point though? As in it’s not until it’s observed later that both particles instantaneously collapse into a correlated state. But the precise outcome of the observation isn’t determined before they’re separated.
My understanding of quantum mechanics is far too limited to really dive into this, but my point isn’t that it enables FTL communication or travel directly.
Rather my understanding is that it appears to break our previous assumptions - physicists haven’t yet settled on a way to unify relativity and quantum physics [1] which leaves many possibilities open. We still just don’t know enough to say it’s definitely impossible.
