Continuous Monitoring of Dynamical Systems and Master Equations
L. F. Lopes Oliveira, R. Rossi, A. R. Bosco de Magalhaes +2
We illustrate the equivalence between the non-unitary evolution of an open quantum system governed by a Markovian master equation and a process of continuous measurements involving…
Effectively irreversible fringe contrast attenuation induced by one degree of freedom
A. R. Bosco de Magalhães, Adélcio C. Oliveira
The attenuation of fringe contrast in a Ramsey interferometer induced by the atom-field interaction is analyzed. We show that short-time power series expansion is not the proper to…
Control of state and state entanglement with a single auxiliary subsystem
R. Rossi, A. R. Bosco de Magalhães, J. G. Peixoto de Faria +1
We present a strategy to control the evolution of a quantum system. The novel aspect of this protocol is the use of a \emph{single auxiliary subsystem}. Two applications are given,…
Incomplete Entanglement: consequences for the QZE
R. Rossi, A. R. Bosco de Magalhaes, M. C. Nemes
We show that the Quantum Zeno Effect prevails even if the entanglement with the measuring probe is not complete. The dynamics towards the asymptotic regime as a function of , th…
Quantum Zeno Effect in Cavity QED: Experimental Proposal with Non Ideal Cavities and Detectors
R. Rossi, A. R. Bosco de Magalhaes, M. C. Nemes
We propose an experiment with two coupled microwave cavities and a "tunneling" photon observed by the passage of Rydberg atoms. We model the coupled cavities as in Ref. \cite{art1}…
