Coherent states superpositions in cavity quantum electrodynamics with trapped ions
F. L. Semiao, A. Vidiella-Barranco
We investigate how superpositions of motional coherent states naturally arise in the dynamics of a two-level trapped ion coupled to the quantized field inside a cavity. We extend o…
Thermal entanglement in the two-qubit Heisenberg XYZ model
G. Rigolin
We study the entanglement of a two-qubit one dimensional XYZ Heisenberg chain in thermal equilibrium at temperature T. We obtain an analytical expression for the entanglement of fo…
Entanglement versus chaos in disordered spin chains
L. F. Santos, G. Rigolin, C. O. Escobar
We use a Heisenberg spin-1/2 chain to investigate how chaos and localization may affect the entanglement of pairs of qubits. To measure how much entangled a pair is, we compute its…
Lower bounds on the entanglement of formation for general Gaussian states
G. Rigolin, C. O. Escobar
We derive two lower bounds on entanglement of formation for arbitrary mixed Gaussian states by two distinct methods. To achieve the first one we use a local measurement procedure d…
Quantum tomography for Dirac spinors
Ricardo A. Mosna, Jayme Vaz
We present a tomographic scheme, based on spacetime symmetries, for the reconstruction of the internal degrees of freedom of a Dirac spinor. We discuss the circumstances under whic…
Ordered Quantization and the Ehrenfest Time Scale
Renato Moreira Angelo, Liliana Sanz, Kyoko Furuya
We propose a prescription to quantize classical monomials in terms of symmetric and ordered expansions of non-commuting operators of a bosonic theory. As a direct application of su…
Dynamics of two atoms coupled to a cavity field
J. A. Roversi, A. Vidiella-Barranco, H. Moya-Cessa
We investigate the interaction of two two-level atoms with a single mode cavity field. One of the atoms is exactly at resonance with the field, while the other is well far from res…
