Abstract
The dynamics of a single qubit randomly colliding with an environment consisting of justtwo qubits is discussed. It is shown that the system reaches an equilibrium state whichcoincides with a pure random state of three qubits. Furthermore the time average andthe ensemble averages of the quantities used to characterize the approach to equilibrium(purity and tangles) coincide, a signature of ergodic behavior.
