摘要：

<正> Abstract We investigate the equivalence of quantum states under local unitary transformations.A complete set ofinvariants under local unitary transformations are presented for a class of non-generic three-qubit mixed states.It isshown that two such states in this class are locally equivalent if and only if all these invariants have equal values forthem.
