    "abstract": "The localization of a quantum state is numerically exhibited in a nonunitary\nNewtonian model for gravity. It is shown that an unlocalized state of a ball of\nmass just above the expected threshold of 10^11 proton masses evolves into a\nmixed state with vanishing coherences above some localization lengths.",
