[1935E. Schrödinger in Proc. Cambr. Philos. Soc. 31 555 By the interaction the two representatives (or ψ-functions) have become entangled. To disentangle them we must gather further information by experiment... In what follows the whole of this procedure will be called the disentanglement.] 1935E. Schrödinger in Proc. Cambr. Philos. Soc. 31 556 Let x and y stand for all the coordinates of the first and second systems respectively and Ψ(x, y) for the normalized representative of the state of the composed system, when the two have separated again, after the interaction has taken place.
