    "abstract": "A purification scheme which utilizes the action of repeated measurements on a\n(part of a total) quantum system is briefly reviewed and is applied to a few\nsimple systems to show how it enables us to extract an entangled state as a\ntarget pure state. The scheme is rather simple (e.g., we need not prepare a\nspecific initial state) and is shown to have wide applicability and\nflexibility, and is able to accomplish both the maximal fidelity and\nnon-vanishing yield.",
