Quantum key distribution provides secure keys with information-theoretic security ensured by the principle of quantum mechanics. The continuous-variable version using coherent states offers advantages its compatibility telecom industry, e.g., commercial laser and homodyne detector, is now going through a booming period. In this review article, we describe system; focus on protocols based states, whose systems are gradually moving from proof-of-principle lab demonstrations to in-field...
Research on optimal eavesdropping models under practical conditions will help to evaluate realistic risk when employing a quantum key distribution system for secure information transmission. Intuitively, fiber loss lead the optical energy leaking environment, rather than harvested by eavesdropper, which also limits ability while improving performance in use. However, defining model presence of lossy is difficult because channel beyond control legitimate partners and leaked signal...
