Towards National Quantum Communication in Europe: Planning and Sizing Terrestrial QKD Networks
Sebastian Raubitzek, Werner Strasser, Sebastian Ramacher +3
The European Union is developing the European Quantum Communication Infrastructure (EuroQCI) as a pan-European network to provide secure communication capabilities across Member St…
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…
Experimental composable key distribution using discrete-modulated continuous variable quantum cryptography
Adnan A. E. Hajomer, Florian Kanitschar, Nitin Jain +6
Establishing secure data communication necessitates secure key exchange over a public channel. Quantum key distribution (QKD), which leverages the principles of quantum physics, ca…
Composable free-space continuous-variable quantum key distribution using discrete modulation
Kevin Jaksch, Thomas Dirmeier, Yannick Weiser +16
Continuous-variable (CV) quantum key distribution (QKD) allows for quantum secure communication with the benefit of being close to existing classical coherent communication. In rec…
Composable Continuous-Variable Multi-User QKD with Discrete Modulation: Theory and Implementation
Florian Kanitschar, Adnan A. E. Hajomer, Michael Hentschel +2
Establishing scalable, secure quantum networks requires advancing beyond conventional point-to-point quantum key distribution (QKD) protocols toward point-to-multipoint QKD protoco…
