arXiv:quant-ph/0602136 · doi:10.1088/0253-6102/45/2/015
Abstract
The equivalence of multipartite quantum mixed states under local unitary transformations is studied. A criterion for the equivalence of non-degenerate mixed multipartite quantum states under local unitary transformations is presented.
