Suppose we produce a polarisation-entangled photon pair ##A_1## and ##A_2##. Then we entangle another pair ##B_1## and ##B_2##.
Now suppose that these photons will not interact with anything, sending ##A_1## and ##B_1## to Alice and ##A_2## and ##B_2## to Bob.
Alice measures the polarisations of the pair of photons she received. Bob however doesn't measure them, but either entangles them correlative or anti-correlative.
I don't know a lot of aspects of this setup, but I ask: what makes transmission of information impossible?
