A uniqueness theorem for entanglement measures

arXiv:quant-ph/0105104 · doi:10.1063/1.1370954

Abstract

We obtain a mathematically simple characterization of all functionals coinciding with the von Neumann reduced entropy on pure states based on the Khinchin-Faddeev axiomatization of Shannon entropy and give a physical interpretation of the axioms in terms of entanglement.
