Attack of Many Eavesdroppers via Optimal Strategy in Quantum Cryptography
Eylee Jung, Mi-Ra Hwang, DaeKil Park +3
We examine a situation that eavesdroppers attack the Bennett-Brassard cryptographic protocol via their own optimal and symmetric strategies. Information gain and mutual informa…
Quantum Resonance near Optimal Eavesdropping in Quantum Cryptography
Eylee Jung, Mi-Ra Hwang, DaeKil Park +6
We find a resonance behavior in the disturbance when an eavesdropper chooses a near-optimal strategy intentionally or unintentionally when the usual Bennett-Brassard cryptographic…
Does three-tangle properly quantify the three-party entanglement for Greenberger-Horne-Zeilinger-type states?
Eylee Jung, DaeKil Park, Jin-Woo Son
Some mixed states composed of only GHZ states can be expressed in terms of only W-states. This fact implies that such states have vanishing three-tangle. One of such rank-3 states,…
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…
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…
Perfect Quantum Teleportation and Superdense coding with states
Eylee Jung, Mi-Ra Hwang, DaeKil Park +2
We conjecture that criterion for perfect quantum teleportation is that the Groverian entanglement of the entanglement resource is . In order to examine the validity of…
