On a biseparability criterion of bipartite qudit state

doi:10.1088/1674-1056/28/8/080302

Abstract In this paper, we propose a new approach to tackle the separability problem for bipartite qudit mixed-states. This is based on the Majorana representation which allows to represent a N-spinors (qudit) as a symmetric state of N spin-1/2. We also discuss how we can exploit such representation and the notion of the biseparability of multipartite qubit states in the sense to establish new criteria of the separability problem based on the PPT and concurrence.

Keywords: separability bipartite qubit state partial separability Majorana representation
