Evaluating the performance of a weak-field homodyne receiver in quadrature phase-shift keying optical communication
Silvia Cassina, Alex Pozzoli, Michele N. Notarnicola +3
Quantum communication protocols require efficient detection schemes to maximize the information transfer rate between the sender and the receiver. To this aim, we have demonstrated…

Security of Binary-Modulated Optical Key Distribution Against Quantum-Enhanced Coherent Eavesdropping
Karol Åukanowski, Karol Łukanowski, MichaÅ Wójcik +4
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…

Discrete-modulation continuous-variable quantum key distribution with probabilistic amplitude shaping over a linear quantum channel
Emanuele Parente, Michele N. Notarnicola, Stefano Olivares +3
The practical implementation difficulties arising from the Gaussian modulation of the GG02 protocol lead us to investigate the possibilities offered by the combination of probabili…
