Effect of Decoherence in Ekert-Protocol
DaeKil Park, Jin-Woo Son, Seong-Keuck Cha +1
We have examined the effect of the decoherence in the Ekert91 quantum cryptographic protocol. In order to explore this issue we have introduced two major decoherences, the depolari…
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…
GHZ versus W : Quantum Teleportation through Noisy Channels
Eylee Jung, Mi-Ra Hwang, You Hwan Ju +7
Which state does lose less quantum information between GHZ and W states when they are prepared for two-party quantum teleportation through noisy channel? We address this issue by s…
