Squeezed- and coherent-state quantum key distribution over a deployed hybrid fibre-free-space channel
Adnan A. E. Hajomer, Huy Q. Nguyen, Ivan Derkach +14
Quantum networks will combine optical fibre with free-space links, yet continuous-variable quantum key distribution (CV-QKD) has been developed predominantly for one medium or the…
Secure Multi-Party Biometric Verification using QKD assisted Quantum Oblivious Transfer
Mariana F. Ramos, Michael Hentschel, Federico Valbusa +7
We present a practical implementation of a secure multiparty computation application enabled by quantum oblivious transfer (QOT) on an entanglement-based physical layer. The QOT pr…
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…
