Forgeable quantum messages in arbitrated quantum signature schemes
Taewan Kim, Hyang-Sook Lee, Soojoon Lee
Recently, the concept on `forgeable quantum messages' in arbitrated quantum signature schemes was introduced by T. Kim et al. [Phys. Scr., 90, 025101 (2015)], and it has been shown…

Critical side channel effects in random bit generation with multiple semiconductor lasers in a polarization-based quantum key distribution system
Heasin Ko, Byung-Seok Choi, Joong-Seon Choe +3
Most polarization-based BB84 quantum key distribution (QKD) systems utilize multiple lasers to generate one of four polarization quantum states randomly. However, random bit genera…
