What's unintuitive that when one complementary oscillation state is measured in one qparticle, we know the other complementary oscillation state in the other qp

  If it were merely "showing information about a distant particle" it would be some variety of a hidden variables theory. Hidden variables theories can be distinguished from others by Bell's inequality. The Aspect experiments demonstrated that Bell's inequality holds in real life.

    Bell’s inequality only rules out local hidden variables. But entanglement and related things like anyons are fundamentally non-local. Anyonic braiding in particular suggests that reality is non-local. AdS/CFT suggests that non-locality (rather than non-determinism) may be the correct solution to resolving the behavior of QM; and more neatly fits with relativity than non-deterministic theories. The article itself starts off correctly saying local realism, but then makes an extraneous assumption that realism rather than locality is incorrect — but that’s not supported by evidence.

      > Bell’s inequality only rules out local hidden variables. Depending on what are the assumptions and the alternatives. If one goes full determinist everything could have a common (local) cause.
