Three-Tangle for Rank-3 Mixed States: mixture of Greenberger-Horne-Zeilinger, W and flipped W states
Eylee Jung, Mi-Ra Hwang, DaeKil Park +1
Three-tangle for the rank-three mixture composed of Greenberger-Horne-Zeilinger, W and flipped W states is analytically calculated. The optimal decompositions in the full range of…
Generalized Schmidt decomposition based on injective tensor norm
Levon Tamaryan, DaeKil Park, Sayatnova Tamaryan
We present a generalized Schmidt decomposition for a pure system with any number of two-level subsystems. The basis is symmetric under the permutation of the parties and is derived…
Role of Three-Qubit Mixed-States Entanglement in Teleportation Scheme
DaeKil Park, Sayatnova Tamaryan, Jin-Woo Son
The bipartite quantum teleportation with a three-qubit mixture of GHZ and W states as a quantum channel is discussed. When the quantum channel is a mixed state consisting of the GH…
Toward an understanding of entanglement for generalized n-qubit W-states
Levon Tamaryan, Hungsoo Kim, Eylee Jung +3
We solve stationarity equations of the geometric measure of entanglement for multi-qubit W-type states. In this way we compute analytically the maximal overlap of one-parameter …
Mixed-State Entanglement and Quantum Teleportation through Noisy Channels
Eylee Jung, Mi-Ra Hwang, DaeKil Park +2
The quantum teleportation with noisy EPR state is discussed. Using an optimal decomposition technique, we compute the concurrence, entanglement of formation and Groverian measure f…
Three-Qubit Groverian Measure
Eylee Jung, Mi-Ra Hwang, DaeKil Park +2
The Groverian measures are analytically computed in various types of three-qubit states. The final results are also expressed in terms of local-unitary invariant quantities in each…
