SLOCC Invariants for Multipartite Mixed States
Naihuan Jing, Ming Li, Xianqing Li-Jost, Ting-Gui Zhang and Shao-Ming Fei
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 $d^2$ invariants for arbitrary $d$-dimensional even partite mixed states are explicitly given.
