Advances in the quantum-state texture theory
Jose Alfredo de Leon, Miguel Gonzalez, Alejandro Fonseca +2
The recently introduced concept of quantum-state texture (QST) has found applications ranging from the identification of unknown quantum gates to the study of quantum phase transit…
Weyl channels for multipartite systems
Tomas Basile, Jose Alfredo de Leon, Alejandro Fonseca +2
Quantum channels, a subset of quantum maps, describe the unitary and non-unitary evolution of quantum systems. We study a generalization of the concept of Pauli maps to the case of…
Pauli component erasing quantum channels
Jose Alfredo de Leon, Alejandro Fonseca, Francois Leyvraz +2
Decoherence of quantum systems is described by quantum channels. However, a complete understanding of such channels, especially in the multi-particle setting, is still an ongoing d…
Tripartite entanglement: Foundations and applications
Márcio M. Cunha, Alejandro Fonseca, Edilberto O. Silva
We review some current ideas about tripartite entanglement, the case representing the next level of complexity beyond the simplest one (though far from trivial), namely the biparti…
High-dimensional quantum teleportation under noisy environments
Alejandro Fonseca
We study the protocol of qudit teleportation using quantum systems subjected to several kinds of noise for arbitrary dimensionality . We consider four classes of noise: dit-flip…
Finite-time collapse process and non-local correlations are incompatible with non-signaling theories
M. G. M. Moreno, Alejandro Fonseca, Márcio M. Cunha
We propose a hidden variable analysis of collapse dynamics in which the state's reduction process may take a finite time . A full characterization of the model is given for the…
