Effect of Phase Factor in the Geometric Entanglement Measure of Three-Qubit States
Sayatnova Tamaryan, Hungsoo Kim, Mu-Seong Kim +2
Any pure three-qubit state is uniquely characterized by one phase and four positive parameters. The geometric measure of entanglement as a function of state parameters can have dif…
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…
