Improved Separability Criteria Based on Bloch Representation of Density Matrices

Sci Rep. 2016 Jun 28:6:28850. doi: 10.1038/srep28850.

Abstract

The correlation matrices or tensors in the Bloch representation of density matrices are encoded with entanglement properties. In this paper, based on the Bloch representation of density matrices, we give some new separability criteria for bipartite and multipartite quantum states. Theoretical analysis and some examples show that the proposed criteria can be more efficient than the previous related criteria.
