Multimode devices and components have attracted considerable attention in the last years,
and different research topics and themes have emerged very recently. The multimodality can …

Quantum key distribution provides secure keys with information-theoretic security ensured
by the principle of quantum mechanics. The continuous-variable version of quantum key …

One of the cornerstones of quantum communication is the unconditionally secure
distribution of classical keys between remote parties. This key feature of quantum …

Quantum key distribution (QKD) is a well-known application of quantum information theory
that guarantees information-theoretically secure key exchange. As QKD becomes more and …

We report a directly modulated distributed feedback laser operating in gain-switching mode
for preparing the coherent states required for the Gaussian-modulated coherent-state …

The continuous-variable quantum digital signature (CV-QDS) scheme relies on the
components of quantum key generation protocol (KGP) to negotiate classical signature …

Nowadays, network speeds are increasing rapidly and network security is a growing
concern. Quantum key distribution (QKD) can provide unconditionally secure keys at the …

In this paper, the performance of a unidimensional continuous variable quantum key
distribution protocol is analyzed using Gaussian modulated coherent state under fast fading …

Continuous-variable quantum key distribution (CV–QKD) is a system that provides secret
keys for symmetric key systems. In the application of CV–QKD, the practical security of the …
