The $\alpha $ -$\eta $ -$\kappa $ -$\mu $ model was recently proposed as a generalized fading and can include all well-known small-scale fading models as special cases. In this letter, we investigate the channel capacity of wireless communications that operate in $\alpha $ -$\eta $ -$\kappa $ -$\mu $ fading channels. More specifically, novel and exact expressions for the channel capacity...
We adopt the standard BB84 protocol as the basic model of quantum key distribution (QKD) in amplitude damping channel and simulate BB84 QKD protocol on classical computer. The simulation results show that the key rate is higher by using binary reconciliation protocol than using cascade reconciliation protocol when the amplitude damping coefficient γ≤0.15, while cascade reconciliation protocol is better...
The B92 protocol is a two quantum states protocol in quantum cryptography. It is one of the basic models of quantum key distribution (QKD) in depolarizing channel. We simulate the rate of secure key distribution in depolarizing channel on a classical computer with the method of event-by-event simulation.After the event-by-event simulation of quantum transmission, data reconciliation and privacy amplification...
