Vibrational Superposition States Without Rotating Wave Approximation
S. Mancini, H. Moya-Cessa, P. Tombesi
We propose a scheme to generate superpositions of coherent states for the vibrational motion of a laser cooled trapped-ion. It is based on the interaction with a standing wave maki…
Nonextensive approach to decoherence in quantum mechanics
A. Vidiella-Barranco, H. Moya-Cessa
We propose a nonextensive generalization (q parametrized) of the von Neumann equation for the density operator. Our model naturally leads to the phenomenon of decoherence, and unit…
Unitary transformation approach for the trapped ion dynamics
H. Moya-Cessa, A. Vidiella-Barranco, J. A. Roversi +1
We present a way of treating the problem of the interaction of a single trapped ion with laser beams based on successive aplications of unitary transformations onto the Hamiltonian…
Cavity Field Reconstruction at Finite Temperature
H. Moya-Cessa, A. Vidiella-Barranco, P. Tombesi +1
We present a scheme to reconstruct the quantum state of a field prepared inside a lossy cavity at finite temperature. Quantum coherences are normally destroyed by the interaction w…
