    "abstract": "An iterative random procedure is considered allowing an entanglement\npurification of a class of multi-mode quantum states. In certain cases, a\ncomplete purification may be achieved using only a single signal state\npreparation. A physical implementation based on beam splitter arrays and\nnon-linear elements is suggested. The influence of loss is analyzed in the\nexample of a purification of entangled N-mode coherent states.",
