    "abstract": "Quantum marking and quantum erasure are discussed for the neutral kaon\nsystem. Contrary to other two-level systems, strangeness and lifetime of a\nneutral kaon state can be alternatively measured via an \"active\" or a \"passive\"\nprocedure. This offers new quantum erasure possibilities. In particular, the\noperation of a quantum eraser in the \"delayed choice\" mode is clearly\nillustrated.",
