    "abstract": "In the present paper, we propose a \"repeat-until-success\" scheme induced by\nsingle particle measurement to generate arbitrary symmetric states based on\nspin network. This protocol requires no modulated controls during the whole\nprocess and it provides a persistent approach towards the desired symmetric\nstate. As a special case, we demonstrate that W state can be created with unit\nprobability within this framework.",
