Matrix realignment and partial transpose approach to entangling power of quantum evolutions
arXiv:quant-ph/0702103 · doi:10.1103/PhysRevA.75.014304
Abstract
Based on the matrix realignment and partial transpose, we develop an approach to entangling power and operator entanglement of quantum unitary operators. We demonstrate efficiency of the approach by studying several unitary operators on qudits, and indicate that these two matrix rearrangements are not only powerful for studying separability problem of quantum states, but also useful in studying entangling capabilities of quantum operators.
