Matrix realignment and partial-transpose approach to entangling power of quantum evolutions
Based on the matrix realignment and partial transpose, we develop an approach to the entangling power and operator entanglement of quantum unitary operators. We demonstrate the approach by studying several unitary operators on qudits, and indicate that these two matrix rearrangements are convenient to use in studying entangling capabilities of …
