Abstract

The existence of two active and passive eraser procedures for neutral kaons was discussed. The quantum marking and quantum eraser were used for the neutral kaon system. The quantum eraser tests were performed with atom interferometers and entangled photon pairs produced through spontaneous paramteric down-conversion (SPDC). It was shown that quantum-eraser experiments sorts strangeness events, which represents the wavelike property of the object kaon. The strangeness content of neutral kaon can be alternatively determined by obbserving their semileptonic decay modes.
