Quantum Decoding with Venn Diagrams
C. M. F. Barros, Francisco Marcos de Assis, H. M. de Oliveira
The quantum error correction theory is as a rule formulated in a rather convoluted way, in comparison to classical algebraic theory. This work revisits the error correction in a no…

Fourier Codes and Hartley Codes
H. M. de Oliveira, C. M. F. Barros, R. M. Campello de Souza
Real-valued block codes are introduced, which are derived from Discrete Fourier Transforms (DFT) and Discrete Hartley Transforms (DHT). These algebraic structures are built from th…
