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…
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…
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…
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…
