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…
Kinetic Roughening of Ion-Sputtered Pd(001) Surface: Beyond the Kuramoto-Sivashinsky Model
T. C. Kim, C. -M. Ghim, H. J. Kim +9
We investigate the kinetic roughening of Ar ion-sputtered Pd(001) surface both experimentally and theoretically. \textit{In situ} real-time x-ray reflectivity and \textit{in si…
