Abstract
The equivalence problem under local unitary transformation for n-partite pure states is reduced to the one for (n-1)-partite mixed states. In particular, a tripartite system âAâ âBâ âCâ, where âj; is a finite-dimensional complex Hilbert space for j=A, B, C, is considered and a set of invariants under local transformations is introduced, which is complete for the set of states whose partial trace with respect to âA belongs to the class of generic mixed states.
