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…

Indirect evidence for the Gouy phase for matter waves

I. G. da Paz, M. C. Nemes, C. H. Monken +2

We show that the well known geometric phase, the Gouy phase in optics can be defined for matter waves in vacuum as well. In particular we show that the underlying physics for the "…
