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…
Is the dynamics of open quantum systems always linear?
Karen M. Fonseca Romero, Peter Talkner, Peter Hänggi
We study the influence of the preparation of an open quantum system on its reduced time evolution. In contrast to the frequently considered case of an initial preparation where the…
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…
