Entanglement swapping secures multiparty quantum communication
Juhui Lee, Soojoon Lee, Jaewan Kim +1
Extending the eavesdropping strategy devised by Zhang, Li and Guo [Phys. Rev. A 63, 036301 (2001)], we show that the multiparty quantum communication protocol based on entanglement…

Convex-roof extended negativity as an entanglement measure for bipartite quantum systems
Soojoon Lee, Dong Pyo Chi, Sung Dahm Oh +1
We extend the concept of the negativity, a good measure of entanglement for bipartite pure states, to mixed states by means of the convex-roof extension. We show that the measure d…

Entanglement measure for any quantum states
Hyuk-jae Lee, Sung Dahm Oh, Doyeol Ahn
The entanglement measure for multiqudits is proposed. This measure calculates the partial entanglement distributed by subsystems and the complete entanglement of the total system.…
