Generation and distribution of atomic entanglement in coupled-cavity arrays
J. P. Mendonça, F. A. B. F. de Moura, M. L. Lyra +1
We study the dynamics of entanglement in a 1D coupled-cavity array, each cavity containing a two-level atom, via the Jaynes-Cummings-Hubbard (JCH) Hamiltonian in the single-excitat…
Localization properties of a two-channel 3D Anderson model
Andre M. C. Souza, Guilherme M. A. Almeida, Eduardo R. Mucciolo
We study two coupled 3D lattices, one of them featuring uncorrelated on-site disorder and the other one being fully ordered, and analyze how the interlattice hopping affects the lo…
Spin chains for two-qubit teleportation
Tony J. G. Apollaro, Guilherme M. A. Almeida, Salvatore Lorenzo +2
Generating high-quality multi-particle entanglement between communicating parties is the primary resource in quantum teleportation protocols. To this aim, we show that the natural…
Interplay between speed and fidelity in off-resonant quantum-state transfer protocols
Guilherme M. A. Almeida
An arbitrary qubit can be transmitted through a spin chain by perturbatively coupling both communicating parties to it. Those so-called weak-coupling models rely on effective Rabi…
Noncommutative quantum Hall effect in graphene
Willien O. Santos, Guilherme M. A. Almeida, Andre M. C. Souza
We discuss the quantum Hall effect on a single-layer graphene in the framework of noncommutative (NC) phase space. We find it induces a shift in the Hall resistivity. Furthermore,…
Disorder-assisted distribution of entanglement in spin chains
Guilherme M. A. Almeida, Francisco A. B. F. de Moura, Tony J. G. Apollaro +1
We study the creation and distribution of entanglement in disordered -type spin- chains for the paradigmatic case of a single flipped spin prepared on a fully polarized ba…
