  We establish duality for monogamy of entanglement: whereas monogamy of
entanglement inequalities provide an upper bound for bipartite sharability of
entanglement in a multipartite system, we prove that the same quantity provides
a \emph{lower} bound for distribution of bipartite entanglement in a
multipartite system.
  Our theorem for monogamy of entanglement is used to establish relations
between bipartite entanglement that separate one qubit from the rest vs
separating two qubits from the rest.
