Entanglement of Indistinguishable Particles Shared between Two Parties
Howard M. Wiseman, John A. Vaccaro · Physical Review Letters · 2003
Using an operational definition we quantify the entanglement, E(P), between two parties who share an arbitrary pure state of N indistinguishable particles. We show that E(P)|1>, where both modes are split between the two parties, has E(P)=1/2. We discuss how this relates to quantum correlations between particles, for both fermions and bosons.
