Detection Power of Separability Criteria Based on a Correlation Tensor: A Case Study
Gniewomir Sarbicki, Giovanni Scala, Dariusz Chruściński · Open Systems & Information Dynamics · 2021
Detection power of separability criteria based on a correlation tensor is tested within a family of generalized isotropic states in [Formula: see text]. For [Formula: see text] all these criteria are weaker than the positive partial transposition (PPT) criterion. Interestingly, our analysis supports the recent conjecture that a criterion based on symmetrically informationally complete positive operator-valued measure (SIC-POVMs) is stronger than realignment criterion.
