    "abstract": "A recent paper claimed to give an entanglement measure for composite systems,\nincluding Bose condensation and superconductivity. It is not an entanglement\nmeasure. It does not distinguish entanglement and non-factorization merely due\nto (anti)symmetrization for identical particles. In fact, the nature of\nentanglement, beyond the effect of (anti)symmetrization, in important states of\nmany identical particles such as Bose condensation and superconductivity, had\nalready been studied earlier.",
