Test of Common Sense in Quantum Copying Process
Mi-Ra Hwang, Eylee Jung, Kap Soo Jang +5
It is believed that the more we have {\it a priori} information on input states, the better we can make the quality of clones in quantum cloning machines. This common sense idea wa…
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…
Correspondence between classical dynamics and energy level spacing distribution in the transition billiard systems
Soo-Young Lee, Sunghwan Rim, Eui-Soon Yim +1
The Robnik billiard is investigated in detail both classically and quantally in the transition range from integrable to almost chaotic system. We find out that a remarkable corresp…
Transitions to quantum chaos in a generic one-parameter family of billiards
Sunghwan Rim, Soo-Young Lee, Eui-Soon Yim +1
Generic one-parameter billiards are studied both classically and quantally. The classical dynamics for the billiards makes a transition from regular to fully chaotic motion through…
Propagator for an Aharonov-Bohm-Coulomb system
D. K. Park, Sahng-Kyoon Yoo, Soo-Young Lee +4
The propagator of three-dimensional Aharonov-Bohm-Coulomb system is calculated by following the Duru-Kleinert method. It is shown that the system is reduced to two independent two…
