Entangled multi-qubit states without higher-tangle
Heng Fan, Yong-Cheng Ou, Vwani Roychowdhury
We analyze mixed multi-qubit states composed of a W class state and a product state with all qubit in |0>. We find the optimal pure state decomposition and convex roofs for higher-…

Bounds on Negativity of Superpositions
Yong-Cheng Ou, Heng Fan
The entanglement quantified by negativity of pure bipartite superposed states is studied. We show that if the entanglement is quantified by the concurrence two pure states of high…

Monogamy Inequality in terms of Negativity for Three-Qubit States
Yong-Cheng Ou, Heng Fan
We propose a new entanglement measure to quantify three qubits entanglement in terms of negativity. A monogamy inequality analogous to Coffman-Kundu-Wootters (CKW) inequality is es…
