Query: Multipartite maximally entangled states in symmetric scenarios   We consider the class of (N+1)-partite states suitable for protocols where
there is a powerful party, the authority, and the other N parties play the same
role, namely the state of their system live in the symmetric Hilbert space. We
show that, within this scenario, there is a "maximally entangled state" that
can be transform by a LOCC protocol into any other state. In addition, we show
how to make the protocol efficiently including the construction of the state
and discuss security issues for possible applications to cryptographic
protocols. As an immediate consequence we recover a sequential protocol that
implements the one to N symmetric cloning.
