Strategies of Legitimate Parties and an Eavesdropper for Discretely Modulated Continuous-Variables Quantum Key Distribution Protocols

2019

Discretely modulated continuous-variables quantum key distribution (CV-QKD) protocols are usually proposed with phase modulated coherent states being sent by Alice and simple homodyne detection on the Bob side and, in the majority of the studies, …

Taming Optical Computing Architectures: From Extreme Learning Machines to Diffractive Neural Networks

2023

Analog processing has recently gained new traction as a result of developments in alternative computing paradigms to the von Neumann one. In particular, concerning optical computing, neuromorphic inspired frameworks strongly simplified the approach to data …

Modulation variance optimization in discrete modulated CV-QKD systems

2023

The distribution of symmetric keys over optical networks is possible through the implementation of continuous variables quantum key distribution (CV-QKD) systems. Despite the rate of key extraction in CV-QKD being maximized for Gaussian modulation (GM), …
