    A mechanism to purify quantum states by Zeno-like measurements was discussed and was applied to simple qubit systems. A pure state was extracted in a quantum system by a series of measurements on another quantum system in interaction with the former. Entanglement purification was one of the application in the purification method. An extension of this method was in the entanglement between two spatially separated qubits which was necessary for quantum communication and quantum teleportation.
