Thenonlocal connection is manifested only in the correlations (revealed througha comparison of the experimental data independently gathered at each of thetwo particles) and not at the level of statistical properties of the particles ateach end of the connection

For Einstein, the crucial part of the argument was the demonstration of nonlocality, that the choice of measurement done in particle A, either position or momentum, would lead to two different quantum states of particle B. He argued that, because of locality, the real state of particle B couldn't depend on which kind of measurement was done in A, and therefore the quantum states cannot be in one-to-one correspondence with the real states.[5]
