Experimental demonstration of phase-remapping attack in a practical quantum key distribution system
, 2010 Unconditional security proofs of various quantum key distribution (QKD) protocols are built on idealized assumptions. One key assumption is: the sender (Alice) can prepare the required quantum states without errors.

Compact free‐electron lasers as enablers of beyond‐6G and quantum communication systems
Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 818-824, May 2026.Compact free‐electron lasers are investigated as scalable, high‐coherence light sources capable of enabling beyond‐6G and quantum communication systems through ultrafast data rates, wide spectral tunability, and high signal‐to‐noise performance.Free‐electron lasers (FELs) are disruptive light sources that offer ultrashort pulses, wide spectral ...

Numerical finite-key analysis of quantum key distribution
npj Quantum Information, 2020 Quantum key distribution (QKD) allows for secure communications safe against attacks by quantum computers. QKD protocols are performed by sending a sizeable, but finite, number of quantum signals between the distant parties involved. Many QKD experiments,

Security of a new two-way continuous-variable quantum key distribution protocol
, 2012 The original two-way continuous-variable quantum-key-distribution (CV QKD) protocols [S. Pirandola, S. Mancini, S. Lloyd, and S. L. Braunstein, Nature Physics 4, 726 (2008)] give the security against the collective attack on the condition of the ...

Ring-Based Quantum Network with Quantum Key Distribution (QKD) and Quantum Digital Signature (QDS)
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Quantum technological developments offers a great promise for implementing secure quantum internet. In this study, we propose a ring topology-based quantum network with QKD and QDS for the quantum internet. The combination of QKD and QDS allows both the detection of the intruder and the increase in security in the network.

Finite-key analysis of a practical decoy-state high-dimensional quantum key distribution
, 2016 Compared with two-level quantum key distribution (QKD), highdimensional QKD enable two distant parties to share a secret key at a higher rate. We provide a finite-key security analysis for the recently proposed practical highdimensional decoy-state QKD ...
