    "abstract": "We suggest a method of generating distillable entanglement form mixed states\nunitarily, by utilizing the flexibility of dimension od occupied Hilbert space.\nWe present a model of a thermal spin state entering a beam splitter generating\nentanglement. It is the truncation of the state that allows for entanglement\ngeneration. The output entanglement is investigated for different temperatures\nand it is found that more randomness - in the form of higher temperature - is\nbetter for this set up.",
