Quantum phase transition in an effective three-mode model of interacting bosons
H. M. Frazão, J. G. Peixoto de Faria, G. Q. Pellegrino +1
In this work we study an effective three-mode model describing interacting bosons. These bosons can be considered as exciton-polaritons in a semiconductor microcavity at the magic…
Two proposals to protect a qubit using CQED techniques: inequality between atomic velocity dispersion and losses of a quantum memory
J. L. Santos, J. G. G. de Oliveira, J. G. Peixoto de Faria +1
We present in this work an analysis of the damage imposed by the atom on the field state inside a lossy superconducting cavity. To access such effects, we propose two procedures to…
Universality of finite time disentanglement
Raphael C. Drumond, Cristhiano Duarte, Marcelo Terra Cunha +1
In this paper we investigate how common is the phenomenon of Finite Time Disentanglement (FTD) with respect to the set of quantum dynamics of bipartite quantum states with finite d…
Atomic Focusing by Quantum Fields: Entanglement Properties
I. G. da Paz, H. M. Frazão, M. C. Nemes +1
The coherent manipulation of the atomic matter waves is of great interest both in science and technology. In order to study how an atom optic device alters the coherence of an atom…
Parametric Competition in non-autonomous Hamiltonian Systems
L. A. M. Souza, J. G. P. Faria, M. C. Nemes
In this work we use the formalism of chord functions (\emph{i.e.} characteristic functions) to analytically solve quadratic non-autonomous Hamiltonians coupled to a reservoir compo…
Quantum Properties of a Which-Way Detector
J. S. Oliveira Filho, R. Rossi, M. C. Nemes
We explore quantum properties of a which-way detector using three versions of an idealized two slit arrangements. Firstly we derive complementarity relations for the detector; seco…
