    "abstract": "Based on the matrix realignment and partial transpose, we develop an approach\nto entangling power and operator entanglement of quantum unitary operators. We\ndemonstrate efficiency of the approach by studying several unitary operators on\nqudits, and indicate that these two matrix rearrangements are not only powerful\nfor studying separability problem of quantum states, but also useful in\nstudying entangling capabilities of quantum operators.",
