    "abstract": "Using an operational definition we quantify the entanglement, $E_P$, between\ntwo parties who share an arbitrary pure state of $N$ indistinguishable\nparticles. We show that $E_P \\leq E_M$, where $E_M$ is the bipartite\nentanglement calculated from the mode-occupation representation. Unlike $E_M$,\n$E_P$ is {\\em super-additive}. For example, $E_P =0$ for any single-particle\nstate, but the state $\\ket{1}\\ket{1}$, where both modes are split between the\ntwo parties, has $E_P = 1/2$. We discuss how this relates to quantum\ncorrelations between particles, for both fermions and bosons.",
