    "abstract": "We determine the degree of entanglement for two indistinguishable particles\nbased on the two-qubit tensor product structure, which is a framework for\nemphasizing entanglement founded on observational quantities. Our theory\nconnects canonical entanglement and entanglement based on occupation number for\ntwo fermions and for two bosons and shows that the degree of entanglement,\nbased on linear entropy, is closely related to the correlation measure for both\nthe bosonic and fermionic cases.",
