Minimax optimization of entanglement witness operator for the quantification of three-qubit mixed-state entanglement
Sungguen Ryu, Seung-Sup B. Lee, H. -S. Sim
We develop a numerical approach for quantifying entanglement in mixed quantum states by convex-roof entanglement measures, based on the optimal entanglement witness operator and th…

Quantifying mixed-state quantum entanglement by optimal entanglement witness
S. -S. B. Lee, H. -S. Sim
We develop an approach of quantifying entanglement in mixed quantum states by the optimal entanglement witness operator. We identify the convex set of mixed states for which a sing…
