Device-Independent Secret Sharing and a Stronger Form of Bell Nonlocality
M. G. M. Moreno, Samuraí Brito, Ranieri V. Nery +1
Bell nonlocality, the fact that local hidden variable models cannot reproduce the correlations obtained by measurements on entangled states, is a cornerstone in our modern understa…
Nonlocality Distillation and Quantum Voids
S. G. A. Brito, M. G. M. Moreno, A. Rai +1
Via nonlocality distillation, a number of copies of a given nonlocal correlation can be turned into a new correlation displaying a higher degree of nonlocality. Apart from its clea…
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…
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…
All bipartitions of arbitrary Dicke states
M. G. M. Moreno, Fernando Parisio
By exploiting the permutation symmetry of Dick states, we derive closed analytical expressions of Schmidt decompositions for {\it all} possible bipartitions of a system described b…
Non-ideal teleportation of tripartite entanglement: Einstein-Podolsky-Rosen versus Greenberger-Horne-Zeilinger schemes
Márcio M. Cunha, E. A. Fonseca, Fernando Parisio
Channels composed by Einstein-Podolsky-Rosen (EPR) pairs are capable of teleporting arbitrary multipartite states. The question arises whether EPR channels are also optimal against…
