Fixed Point Exploration For CV-QKD IR QC-MET-LDPC Toward Hardware Implementation
Guilherme Vergne de Oliveira, Mauro Queiroz Nooblath Neto, Micael Andrade Dias +4
High-speed LDPC decoding is a major bottleneck in CV-QKD and motivates hardware acceleration with fixed-point arithmetic. This work compares SPA, MSA, and NMS under a unified low-S…
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…
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…
Entanglement-assisted Quantum Codes from Algebraic Geometry Codes
Francisco Revson F. Pereira, Ruud Pellikaan, Giuliano Gadioli La Guardia +1
Quantum error correcting codes play the role of suppressing noise and decoherence in quantum systems by introducing redundancy. Some strategies can be used to improve the parameter…
New Convolutional Codes Derived from Algebraic Geometry Codes
Francisco Revson F. Pereira, Giuliano G. La Guardia, Francisco M. de Assis
In this paper, we construct new families of convolutional codes. Such codes are obtained by means of algebraic geometry codes. Additionally, more families of convolutional codes ar…
Protecting Information Against Computational Errors and Quantum Erasures via Concatenation
Gilson O. dos Santos, Francisco M. de Assis
In this work, we introduce a new concatenation scheme which aims at protecting information against the occurrence of both computational errors and quantum erasures. According to ou…
Unconditional Security with Decoherence-Free Subspaces
Elloá B. Guedes, Francisco M. de Assis
We show how to use decoherence-free subspaces over collective-noise quantum channels to convey classical information in perfect secrecy. We argue that codes defined over decoherenc…
A scheme to protect against multiple quantum erasures
Gilson O. dos Santos, Francisco M. de Assis
We present a scheme able to protect k >= 3 qubits of information against the occurrence of multiple erasures, based on the code proposed by Yang et al. (2004 JETP Letters 79 236).…
A Scheme of Concatenated Quantum Code to Protect against both Computational Error and an Erasure
G. O. Santos, F. M. Assis, A. F. Lima
We present a description of encoding/decoding for a concatenated quantum code that enables both protection against quantum computational errors and the occurrence of one quantum er…
