A note on "A Matrix Realignment Method for Recognizing Entanglement," quant-ph/0205017 v1
Abstract
Description
In quant-ph/0205017 v1 Chen, Wu and Yang formulated a necessary separability criterion based on a realignment method for matrices. This note is to point out that this criterion is identical to the necessary cross norm criterion previously put forward by this author.
