Let $U$ and $U'$ be bipartite unitary operators on $\mathcal{H}_3\otimes\mathcal{H}_3$. They are local unitarily equivalent if there exist single-qutrit unitary gates…

Let two stabilizer states be given. They are local unitary equivalent if there exists a product of unitary operators, one acting on each qubit, that maps one state to the other; th…
