Novel quantum phenomena have been recently discussed in association to a peculiar time correlation between entangled neutral kaons produced at a $\phi$-factory: the past state of the first decayed kaon, when it was still entangled before its decay, is post-tagged by the result and the time of the future observation on the other kaon decay. This surprising ``from future to past'' effect is fully observable. Preliminary results obtained on the analysis of data collected by the KLOE experiment at the DA$\Phi$NE collider are presented, showing experimental evidence of this new effect.
