Recovery-Induced Erasure Attack on QKD Systems
Hashir Kuniyil, Asad Ali, Syed M. Arslan +3
Detector dead time is typically treated as a fixed parameter in quantum key distribution (QKD) security analyses. In practice, however, the effective recovery time of single-photon…

Optical downlink modeling for low-earth-orbit and medium-earth-orbit satellites under atmospheric turbulence with a quantum-state-tomography use case
Artur Czerwinski, Jakub J. Borkowski, Saeed Haddadi +1
This paper presents a comprehensive analysis of the link budget for free-space optical systems involving Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) satellites. We develop a…

Comment on Quantum illumination using polarization-entangled photon pairs for enhanced object detection (Opt. Express 32, 40150-40164, 2024)
Artur Czerwinski, Jakub J. Borkowski
The paper by K. Sengupta et al. (Opt. Express 32, 40150-40164, 2024) explores quantum illumination using polarization-entangled photon pairs for object detection in noisy environme…
