Generalizing Choi map in beyond circulant scenario
arXiv:2212.03807
Abstract
We present a generalization of the family of linear positive maps in proposed thirty years ago by Cho et al. (Linear Algebra Appl. , 213 (1992)) as a generalization of the seminal Choi non-decomposable map. The necessary and sufficient conditions for decomposability are provided.
