Quantum entanglement estimation via symmetric measurement based positive maps
Jiaxin Li, Hongmei Yao, Shao-Ming Fei +2
We provide a class of positive and trace-preserving maps based on symmetric measurements. From these positive maps we present separability criteria, entanglement witnesses, as well…
