Abstract

We construct a nontrivial set of invariants for any multipartite mixed states under the SLOCC symmetry. These invariants are given by hyperdeterminants and independent from basis change. In particular, a family of d² invariants for arbitrary d-dimensional even partite mixed states are explicitly given.
