Non-Gaussianity and security of entanglement-based QKD
Mariia Gumberidze, Vladyslav C. Usenko
We theoretically analyse the relation between non-Gaussianity and security of entanglement-based quantum key distribution (QKD) protocols, namely device-independent (DI) and entang…
Feasibility of entanglement-based QKD protocols with SPDC and QD sources
Mariia Gumberidze, Vladyslav C. Usenko
We theoretically analyze the feasibility of entanglement-based quantum key distribution (QKD) protocols considering widely used spontaneous parametric down-conversion (SPDC) and no…
Practical continuous-variable quantum key distribution with squeezed light
Huy Q. Nguyen, Ivan Derkach, Akash nag Oruganti +6
Continuous-variable quantum key distribution (CV-QKD) has gathered significant interest for its potential to achieve high secret key rates and seamless integration with existing op…
Coexistence of continuous-variable quantum key distribution and classical data over 120-km fiber
Adnan A. E. Hajomer, Ivan Derkach, Vladyslav C. Usenko +2
Integrating quantum key distribution (QKD) with classical data transmission over the same fiber is crucial for scalable quantum-secured communication. However, noise from classical…
Finite-size security of continuous-variable quantum key distribution with imperfect heterodyne measurement
Adnan A. E. Hajomer, Akash Nag Oruganti, Ivan Derkach +3
Continuous-variable quantum key distribution (CVQKD) using coherent states and heterodyne detection enables secure quantum communication based on technology that has large similari…
Continuous-variable quantum communication
Vladyslav C. Usenko, Antonio Acín, Romain Alléaume +8
Tremendous progress in experimental quantum optics in recent decades has enabled the advent of quantum technologies, one of which is quantum communication. Aimed at novel methods f…
