The entanglement of indistinguishable particles shared between two parties

Entanglement of indistinguishable particles E_p shared between two separated parties is introduced. Definition of E_p is operationally based in that E_p quantifies the amount of entanglement that can be transferred to another system using local operations (LO), and thus it quantifies the amount of entanglement that can be used as a resource. Pure states |ψ_AB> for the particles shared between two parties, Alice and Bob are considered. For genuine particles (such as electrons or hydrogen atoms), as opposed to gauge bosons (such as photons), there is a conservation law that rules out the creation of superpositions of different number eigenstates. Thus, it is assumed that the state |ψ_AB> of the indistinguishable particles contains exactly N particles.
