Abstract: We introduce a concept of local unitary (LU) transformation invariant operators which permits us to easily obtain arbitrary multi-qubit states LU transformation invariant. The general relation between the LU transformation invariant and perfect quantum teleportation is examined. The optimal match of measurement basis is given.
