Long-time-scale revivals in ion traps
H. Moya-Cessa, A. Vidiella-Barranco, J. A. Roversi +2
In this contribution we investigate the interaction of a single ion in a trap with laser beams. Our approach, based on unitary transformating the Hamiltonian, allows its exact diag…
Field Purification in the intensity-dependent Jaynes-Cummings model
D. S. Freitas, A. Vidiella-Barranco, J. A. Roversi
We have found that, in the intensity-dependent Jaynes-Cummings model, a field initially prepared in a statistical mixture of two coherent states, and , evolves toward a…
Quantum state engineering via unitary transformations
A. Vidiella-Barranco, J. A. Roversi
We construct a Hamiltonian for the generation of arbitrary pure states of the quantized electromagnetic field. The proposition is based upon the fact that a unitary transformation…
