We find novel quantum phenomena associated to a correlation in time between the two partners: The past state of the first decayed kaon, when it was entangled before its decay, is post-tagged by the result and the time of the future observation of the second decay channel. This surprising {\textquoteleft}{\textquoteleft}from future to past{\textquoteright}{\textquoteright} effect is fully observable and leads to the unique experimental tag of the K-S state, an unsolved problem since the discovery of CP violation.", optnote="WOS:000892122400008", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5431), last updated on Wed, 28 Dec 2022 08:20:02 +0000", issn="2470-0010", doi="10.1103/PhysRevD.105.116004", opturl="https://arxiv.org/abs/1912.04798", opturl="https://doi.org/10.1103/PhysRevD.105.116004", language="English" }
