    "abstract": "We present a novel procedure to purify quantum states, i.e., purification\nthrough Zeno-like measurements. By simply repeating one and the same\nmeasurement on a quantum system, one can purify another system in interaction\nwith the former. The conditions for the (efficient) purification are specified\non a rather general setting, and the framework of the method possesses wide\napplicability. It is explicitly demonstrated on a specific setup that the\npurification becomes very efficient by tuning relevant parameters.",
