Security of Binary-Modulated Optical Key Distribution Against Quantum-Enhanced Coherent Eavesdropping
Karol Łukanowski, Michał Wójcik, Stefano Olivares +2
Optical key distribution (OKD) protects the physical layer of communication links by taking advantage of the inherent noise present in the photodetection process. It allows for eff…
Quantum Pulse Gate Attack on IM/DD Optical Key Distribution Exploiting Symbol Shape Distortion
M. Jarzyna, M. Jachura, K. Banaszek
Intensity modulation/direct detection (IM/DD) optical key distribution (OKD) is a method to generate a secret key whose security against passive eavesdropping is guaranteed by the…
Beating the spectroscopic Rayleigh limit via post-processed heterodyne detection
Wiktor Krokosz, Mateusz Mazelanik, Michał Lipka +4
Quantum-inspired superresolution methods surpass the Rayleigh limit in imaging, or the analogous Fourier limit in spectroscopy. This is achieved by carefully extracting the informa…
Optimizing state-discrimination receivers for continuous-variable quantum key distribution over a wiretap channel
Michele N. Notarnicola, Marcin Jarzyna, Stefano Olivares +1
We address a continuous-variable quantum key distribution (CV-QKD) protocol employing quaternary phase-shift-keying (QPSK) of coherent states and a non-Gaussian measurement inspire…
Quantum Limits on the Capacity of Multispan Links with Phase-sensitive Amplification
Karol Łukanowski, Konrad Banaszek, Marcin Jarzyna
Long-distance fiber communication stands as a cornerstone of modern technology. One of the underlying principles, preventing signal levels from diminishing below the detectability…
Quantum Limits on the Capacity of Multispan Links with Phase-Sensitive Amplification
Karol Łukanowski, Marcin Jarzyna, Konrad Banaszek
The capacity of a linear attenuating optical channel with the signal regenerated using quantum-limited phase-sensitive amplifiers is analyzed for conventional and generalized detec…
