Abstract :
We study the evolution of entanglement and nonlocality of a non-interacting
qubit-qutrit system under the effect of random telegraph noise (RTN) in independent
and common environments in Markovian and non-Markovian regimes. We investigate
the dynamics of qubit-qutrit system for different initial states. These systems could
be existed in far astronomical objects. A monotone decay of the nonlocality (entan-
glement) is found in the Markov regime, while for non-Markovian noise, phenomena
of sudden change (death) and revival occurs. We nd that the preserving nonlocality
(entanglement) depends on initial state of the system in common and independent en-
vironments; so, we can not strictly conclude that independent or common environments
are more robust against the noise.
