Erasing the Past and Impacting the Future with Kaons at a Phi-factory

The well known quantum eraser concepts are applied to entangled kaons. Due to different measurement procedures, a specific feature of neutral kaons not shared by other quantum systems, we show that novel options for the quantum eraser phenomena open. Moreover, the proposed kaonic erasers may in future be experimentally demonstrated with the upgraded KLOE detector at the φ –factory
