Single-Qudit Quantum Neural Networks for Multiclass Classification

Leandro C. Souza, Renato Portugal

This paper proposes a single-qudit quantum neural network for multiclass classification, by using the enhanced representational capacity of high-dimensional qudit states. Our desig…

Moments of Coinless Quantum Walks on Lattices

Raqueline A. M. Santos, Renato Portugal, Stefan Boettcher

The properties of the coinless quantum walk model have not been as thoroughly analyzed as those of the coined model. Both evolve in discrete time steps but the former uses a smalle…
