An analytical relation between entropy production and quantum Lyapunov exponents for Gaussian bipartite systems
K. M. Fonseca Romero, J. E. Parreira, L. A. M. Souza +2
We study and compare the information loss of a large class of Gaussian bipartite systems. It includes the usual Caldeira-Leggett type model as well as Anosov models (parametric osc…

Realistic Decoherence Free Subspaces
K. M. Fonseca Romero, S. G. Mokarzel, M. O. Terra Cunha +1
Decoherence free subspaces (DFS) is a theoretical tool towards experimental implementation of quantum information storage and processing. However, they represent an experimental ch…
