Secret Key Rate Analysis of Distribution Matching Algorithms for Discrete-Modulated CV-QKD
Micael Dias, Caroline Alves, Gabrielly Roman +1
Continuous variable quantum key distribution protocols (CV-QKD) with discrete modulation have been intensively investigated to bridge the gap between ideal Gaussian modulation and…
Arithmetic Reconciliation for CVQKD: Challenges and Feasibility
Rávilla R. S. Leite, Juliana M. de Assis, Micael A. Dias +1
Continuous variable quantum key distribution allows two legitimate parties to share a common secret key and encompasses reconciliation protocols. A relatively new reconciliation pr…
A condition for the zero-error capacity of quantum channels
Marciel M. Oliveira, Francisco M. de Assis, Micael A. Dias
In this paper, we present a condition for the zero-error capacity of quantum channels. To achieve this result we first prove that the eigenvectors (or eigenstates) common to the Kr…
Convergence of Density Operators and Security of Discrete Modulated CVQKD Protocols
Micael Andrade Dias, Francisco Marcos de Assis
This communication deals with the problem of bounding the approximation error on weak convergence of mixed coherent state towards a Gaussian thermal state. In the context of CVQKD…
A method for Sampling Bernoulli Variables
Francisco Marcos de Assis, Juliana Martins de Assis, Micael Andrade Dias
We introduce new method for generating correlated or uncorrelated Bernoulli random variables by using the binary expansion of a continuous random variable with support on the unit…
Converging State Distributions for Discrete Modulated CVQKD Protocols
Micael Andrade Dias, Francisco Marcos de Assis
Consider the problem of using a finite set of coherent states to distribute secret keys over a quantum channel. It is known that computing the exact secret key rate in this scenari…
Distributional Transform Based Information Reconciliation
Micael Andrade Dias, Francisco Marcos de Assis
In this paper, we present an information reconciliation protocol designed for Continuous-Variable QKD using the Distributional Transform. By combining tools from copula and informa…
Evaluating the Eavesdropper Entropy via Bloch-Messiah Decomposition
Micael Andrade Dias, Francisco Marcos de Assis
We explore the Bloch-Messiah decomposition of Gaussian unitary to analyze the Entangling Cloner Attack performed by an eavesdropper on a discrete modulated continuous variable QKD…
Amplitude-Phase Modulated CVQKD Protocol
Micael Andrade Dias, Francisco Marcos de Assis
Here we report the performance of a discrete modulated Continuous Variable Quantum Key Distribution protocol based on eight and sixteen state optimal Amplitude Phase Keying constel…
