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…
Survey on the Bell nonlocality of a pair of entangled qudits
Alejandro Fonseca, Anna de Rosier, Tamás Vértesi +2
The question of how Bell nonlocality behaves in bipartite systems of higher dimensions is addressed. By employing the probability of violation of local realism under random measure…
Using three-partite GHZ states for partial quantum error-detection in entanglement-based protocols
M. G. M. Moreno, Alejandro Fonseca, Márcio M. Cunha
The problem of noise incidence on qubits taking part of bipartite entanglement-based protocols is addressed. It is shown that the use of a three-partite GHZ state and measurements…
