Matrix rearrangement approach for the entangling power with mixed qudit systems
Xiao-Ming Lu, Xiaoguang Wang, Yang Yang +1
We extend the former matrix rearrangement approach of the entangling power to the general cases, without the requirement of the same dimensions of the subsystems. The entangling po…
