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…
Parallel Computation of PDFs on Big Spatial Data Using Spark
Ji Liu, Noel Moreno Lemus, Esther Pacitti +2
We consider big spatial data, which is typically produced in scientific areas such as geological or seismic interpretation. The spatial data can be produced by observation (e.g. us…
Quantum search on the two-dimensional lattice using the staggered model with Hamiltonians
Renato Portugal, Tharso D. Fernandes
Quantum search on the two-dimensional lattice with one marked vertex and cyclic boundary conditions is an important problem in the context of quantum algorithms with an interesting…
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…
Self-Interacting Electromagnetic Fields and a Classical Discussion on the Stability of the Electric Charge
S. O. Vellozo, José A. Helayël-Neto, A. W. Smith +1
The present work proposes a discussion on the self-energy of charged particles in the framework of nonlinear electrodynamics. We seek magnet- ically stable solutions generated by p…
Magnetic Moment Generation from non-minimal couplings in a scenario with Lorentz-Symmetry Violation
H. Belich, L. P. Colatto, T. Costa-Soares +2
This paper deals with situations that illustrate how the violation of Lorentz symmetry in the gauge sector may contribute to magnetic moment generation of massive neutral particles…
