The required interchange of \"in\" $\\leftrightarrow$ \"out\" states for a given process is obtained exploiting the Einstein-Podolsky-Rosen correlations of neutral kaon pairs produced at a $\\phi$-factory. The observable quantities have been constructed by selecting the two semileptonic decays for flavour tag, the $\\pi\\pi$ and $3\\pi^0$ decays for CP tag and the time orderings of the decay pairs.
